FIELD OF INVENTION
This invention relates to a system for clamping and lubricating balancer
assembly. The system is helpful in balancing engine and lubricating balancer
shaft.
PRIOR ART
In the existing engines Balancer Assembly is provided to balance the Primary
forces of the engine. Normally balancer is mounted in the engine block with
extra tapping in the Block and lubrication is provided to the Balancer Housing
through a filtered oil passage gallery.
Mounting the balancer in two cylinder even firing engIne is always a great
challenge wherein space and lubrication are the key factors.
Balancer is mandatory for two cylinder engine where firing order gap is 3600
only instead of 1800 of crank angle. In this case both the pins of crank shaft
are always in one direction. This creates unbalance and to counter this
balancer is required. Further, pressurized lubrication is required because it
rotates with same speed of engine.
However, the known engine balancer assembly is associated with the following
disadvantages: -
More machining effort.
More requirement of hardware.
- Assembly constraints.
Several leakage prone areas.

Hence, the present invention has been introduced to address the aforesaid
drawbacks and provide other benefits as usual.
OBJECTS OF THE INVENTION
The primary object of the present invention is to provide a system for clamping
and lubricating balancer assembly which overcomes disadvantages associated
with the prior art.
Another object of the present invention is to provide a system for clamping and
lubricating balancer assembly which is simple in construction.
Further object of the present invention is to provide a system for clamping and
lubricating balancer assembly which is reliable and efficient.
At the outset of the description, which follows, it is to be understood that the
ensuing description only illustrates a particular form of this invention.
However, such a particular form is only an exemplary embodiment, without
intending to imply any limitation on the scope of this invention. Accordingly,
the description is to be understood as an exemplary embodiment and teaching
of the invention and not intended to be taken restrictively.
BRIEF DESCRIPTION OF THE INVENTION
According to this invention, there is provided a system for clamping and
lubricating balancer assembly comprising of a bolt and nut arrangement with
an integrated hole in the bolt.

Now, reference may be made to sheet 1, wherein compact balancer housing is
provided to balance the rotational masses for a two cylinder even firing engine.
The bolt is used for various purposes.
It helps in clamping the balancer housing with the engine block.
With the help of integrated hole in the bolt, it serves the purpose of lubricating
the balancer housing. Further, a welch plug which seals the lubricating oil
gallery can also be removed with the help of the bolt and nut arrangement.
Features of the invention
- To clamp balancer housing to engine block.
- To close the lubrication oil gallery of the engine block.
- To provide lubrication to the balancer housing.
Removal of extra hardware to mount balancer housing.
Removal of extra plug and also removal of additional machining of
lubrication oil gallery in the engine block.
Leakage proof.
Minimizes machining effort.
No assembly constraints.
