Abstract
A balancer of a reciprocating machine having crank mechanisms includes an adjusting weight having one end supported by a reciprocating portion of a crank mechanism for the balancer. An adjusting weight support rotatably supports the other end of the adjusting weight with respect to a stationary portion of a body frame. The adjusting weight support is equipped with a weight support position altering mechanism for permitting alteration of the support position of the adjusting weight.
Claims7
In a balancer for balancing the unbalanced inertia force of a reciprocating machine of the type including a reciprocating member for converting rotary motion into reciprocating motion by the use of a first crank mechanism, said balancer including at least one supporting balance weight on a reciprocating portion of a second crank mechanism for said balancer that has an eccentric setting angle shifted 180.degree. in phase with respect to the eccentric angle of the first crank mechanism, the improvement comprising:
- at least one adjusting weight having a first end supported by said reciprocating portion of said second crank mechanism;
- an adjusting weight supporting means for rotatably supporting a second end of said adjusting weight with respect to a stationary portion of a body frame;
- and
- weight support position altering mechanism means fixedly mounted on said stationary portion of said body frame for selectively altering the position of support of said second end of said adjusting weight by said adjusting weight supporting means and thereby for adjusting the distance between the positions of support at said first and second ends of said adjusting weight.
