Specification

The present disclosure relates to the field of retaining arrangements for retaining a gear on a shaft.
BACKGROUND
Conventionally, a gear is axially secured with a step on a shaft using multiple spacers. Typically, a gear, mounted on a connecting shaft of a vehicle, is axially secured at one end thereof by a first spacer and a step on shaft. A bearing is mounted on the connecting shaft proximal to the gear. The axial displacement of the gear towards the bearing is restricted by disposing a second spacer between the gear and the bearing. An undercut is provided on the shaft for receiving the first spacer. The first spacer restricts the axial displacement of the gear on the shaft in the direction opposite to the bearing. Step on connecting shaft restricts the axial displacement of the first spacer. However, when the shaft is subjected to torsional loads, the shaft may break at the location where the undercut is configured. Further, a circlip is mounted on the shaft to restrict the axial displacement of the bearing. However, in case of torsional loads, the circlip may break due to lesser contact area between the bearing and the circlip. Failure of the circlip leads to failure of bearing as the bearing gets displaced from its desired position.
Therefore, there is felt a need of a gear retaining arrangement that alleviates the abovementioned drawbacks of the conventional arrangements and securely retains a gear on a shaft.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:

An object of the present disclosure is to provide a gear retaining arrangement that securely retains a gear on a shaft.
Another object of the present disclosure is to provide a gear retaining arrangement that prevents failure of a shaft and a bearing mounted on the shaft.
Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.
SUMMARY
The present disclosure envisages a gear retaining arrangement for securely retaining a gear on a stepped shaft. The gear retaining arrangement comprises a first spacer and a snap ring. The first spacer is mounted in the inner circumferential surface of gear and rests on the stepped portion of the shaft. The snap ring is securely received in a groove configured on an inner circumferential surface of the gear. In an operative configuration, the snap ring abuts the first spacer. The displacement of the first spacer is restricted by the snap ring in at least one longitudinal direction, thereby axially securing the gear on the shaft.
The gear retaining arrangement further comprises a bearing, a circlip and a second spacer. The bearing is mounted on the shaft, and is configured for rotatably supporting the shaft. The circlip is mounted on the shaft proximal to the bearing mounted on the shaft. The circlip is configured to restrict axial movement of the bearing mounted on the shaft. The second spacer is mounted on the shaft between the circlip and the bearing to provide surface contact area to the circlip.
A third spacer is mounted on the shaft between the bearing and the gear to restrict axial displacement of the gear towards the bearing. The snap ring restricts displacement of the gear in a longitudinal direction opposite to the bearing.

In an embodiment, the circlip is a heavy duty circlip.
In another embodiment, the stepped shaft is a splined shaft.

DETAILED DESCRIPTION
Figure 1 illustrates a cross sectional view of a conventional arrangement 100 for retaining a gear 105 on a shaft 110. The shaft 110 is a stepped splined shaft. Typically, the shaft 110 is a connecting shaft of a gearbox (not shown in figures). Further, the gear 105 is engaged with respective gear mounted on an input shaft (not shown in figures) of the gearbox. The shaft 110 is rotatably supported at one end thereof by a bearing 130. In the conventional arrangement 100, the gear 105 is axially secured at one end thereof by a first spacer 115. An undercut 120 is provided on the shaft 110 for proper butting of the first spacer 115. The first spacer 115 restricts the axial displacement of the gear 105 on the shaft 110 as the first spacer 115 is secured in the step on the shaft. Further, a second spacer 135 is mounted on the shaft 110 between the gear 105 and the bearing 130. The second spacer 135 restricts the axial displacement of the gear 105 towards the bearing 130. However, the formation of the undercut 120 weakens the shaft 110. When the shaft 110 is subjected to torsional loads, the shaft 110 may deform or may even break due to the undercut 120. Further, the bearing 130 is axially secured on the shaft 110 via a circlip 125. Typically, the circlip 125 is a light duty circlip. When the shaft 110 is subjected to torsional loads,

the circlip 125 may break due to lesser available contact area between the bearing 130 and the circlip 125. Failure of the circlip 125 leads to leads to failure of bearing 130 as the bearing 130 gets displaced from its desired position. Further, the displacement of the bearing 130 leads to displacement of the gear 105 on the shaft 110.
5 The present disclosure envisages a gear retaining arrangement that securely retains a
gear on a shaft, and prevents failure of the shaft and a bearing mounted on the shaft.
The gear retaining arrangement of the present disclosure is hereinafter described with
reference to figure 2 and figure 3 which illustrate a cross-sectional view of a gear
retaining arrangement 200, in accordance with an embodiment of the present
10 disclosure.
Referring to figure 2 and figure 3, the gear retaining arrangement 200 is configured to securely retain a gear 205 on a stepped shaft 210. The gear 205 is rotatably mounted on the stepped portion of the shaft 210 such that a portion of the gear 205 is supported by the splined portion of the shaft 210. In an embodiment, the stepped shaft
15 210 is a splined stepped shaft configured for facilitating mounting of the gear 205
thereon. In an exemplary embodiment, the stepped shaft 210 is a connecting shaft of a gearbox, and the gear 205 is constantly engaged with another gear mounted on an input shaft of the gearbox. The shaft 210 is rotatably supported at one end thereof by a bearing 230. In an embodiment, the gear 205, the shaft 210, and the bearing 230 are
20 housed within a housing 245 of the gearbox.
The gear retaining arrangement 200 comprises a first spacer 215 and a snap ring 220.
The first spacer 215 is mounted in the inner circumferential area of gear 205 on the
step provided on stepped shaft 210. The snap ring 220 is securely received in a
groove 222 configured on an inner circumferential surface of the gear 205. In an
25 operative configuration, the snap ring 220 abuts the first spacer. More specifically,
the groove 222 is configured on the portion of the gear which is not supported by the
6

stepped portion of the shaft 210. Thus, the first spacer 215 is sandwiched between the
snap ring 220 and the stepped portion of the shaft 210. The displacement of the snap
ring 220 is restricted in groove 222. The displacement of the first spacer 215 is
restricted by the snap ring 220 in at least one longitudinal direction. In an
5 embodiment, the snap ring 220 restricts the displacement of the first spacer 215 in a
longitudinal direction opposite to that of the bearing 230. Thus, the displacement of the gear 205 also gets restricted in a direction opposite to that of the bearing 230 by the snap ring 220. This axially secures the gear 205 on the shaft 210.
The gear retaining arrangement 200 further comprises the bearing 230, a circlip 225
10 and a second spacer 235. The bearing 230 is mounted on the shaft, and configured for
rotatably supporting the shaft 210. The circlip 225 is mounted on the shaft 210
proximal to the bearing 230 mounted on the shaft 210. The circlip 225 is configured
to restrict the axial movement of the bearing 230 on the shaft 210. More specifically,
the circlip 225 is mounted on an operative end of the shaft 210 proximal to the
15 bearing 230.
In an embodiment, the circlip 225 is a heavy duty circlip. The circlip 225 does not break or deform when the shaft 210 is subjected to axial loads.
Further, the second spacer 235 is mounted on the shaft 210 between the circlip 225
and the bearing 230. The second spacer 235 provides enough surface contact area to
20 the circlip 225 in order to prevent failure of circlip 225 due to axial loads.
The gear retaining arrangement 200 further comprises a third spacer 240 mounted on the shaft 210 between the bearing 230 and the gear 205. The third spacer 240 restricts the axial displacement of the gear 205 towards the bearing 230.
In gear retaining arrangement 200, the third spacer 240 restricts the longitudinal
25 displacement of the gear 205 towards the bearing 230, while the first spacer 215 and
the snap ring 220 restricts the displacement of the gear 205 in the longitudinal
7

direction opposite to that of the bearing 230. Thus, the gear 205 is axially secured on the shaft 210.
The gear 205, the first spacer 215, the snap ring 220, the third spacer 240, the bearing 230, the second spacer 235, and the circlip 225 form a tight stack that does not get 5 displaced on the shaft 210.
As the gear retaining arrangement 200 does not require any undercuts on the shaft, the possibility of failure of the shaft due to undercut is eliminated. Further, the second spacer 235 provides enough contact area to prevent failure of the circlip 225, and hence, the bearing 230.
