Abstract
The utility model discloses a balance mechanism for the reciprocating inertial force of an engine. The balance mechanism comprises an air cylinder, a crankshaft, an engine body frame component with a bellcrank. A balancing cylinder parallel with the central line of the air cylinder is arranged on the engine body frame component. A balancing cylinder piston capable of reciprocating is arranged in the balancing cylinder. The balancing cylinder bellcrank is arranged on the crankshaft. The balancing cylinder piston is connected with the balancing cylinder bellcrank through the connecting rod of the balancing cylinder. The balance mechanism is simple in structure with low processing requirements, which is produced conveniently.
Description
Technical field
The utility model relates to a kind of motor reciprocal inertia force balanced controls.
Background technique
At present, Chang Yong single cylinder (and the crank throw angle is 0 ° a two cylinder) engine start machine reciprocal inertia force balanced controls reach the balance purpose by trunnion shaft is set.Trunnion shaft is parallel to bent axle, and the angular velocity of trunnion shaft equals the angular velocity of bent axle, and balancer weight is housed on the trunnion shaft; Trunnion shaft connects with bent axle by gear.The balancer weight centrifugal force of trunnion shaft is in the then synthetic power along the cylinder centerline directive effect of the component that is parallel to the gas centerline direction, and direction is opposite with reciprocal inertia force is equal for its size, has so just reached balance.This balanced controls structure more complicated, processing request is higher.
Summary of the invention
The utility model purpose is: in order to overcome complex structure in the prior art, the higher shortcoming of processing request, provide a kind of new balanced controls, this mechanism structure is simple, and processing request is low, is convenient to produce.
The technical solution of the utility model is: a kind of motor reciprocal inertia force balanced controls, comprise have cylinder, the engine body frame component of bent axle, crank throw, body, support, wherein support and body are arranged on the bent axle both sides and cooperatively interact, cylinder arrangement is in body, be formed with a compensating cylinder that is parallel to cylinder centerline in the support, be provided with reciprocating compensating cylinder piston in the compensating cylinder, the compensating cylinder piston is fastenedly connected with the compensating cylinder connecting rod by nut, and the other end of compensating cylinder connecting rod is connected with compensating cylinder crank throw on being arranged on bent axle.Wherein, the eccentric direction of compensating cylinder crank throw is away from the crank throw direction, and compensating cylinder crank throw center line, crankshaft axis and crank throw centerline are in same plane;
During engine running, the compensating cylinder crank throw of bent axle drives the compensating cylinder connecting rod, make the compensating cylinder piston that is installed on the compensating cylinder connecting rod in compensating cylinder, do the to-and-fro motion opposite, produce the power with the reciprocal inertia force opposite sign but equal magnitude, reach the balance purpose with the engine piston motion direction.
The utility model advantage is:
1. the utility model is simple in structure, and processing request is low, is convenient to produce.
2. the utility model has improved the reliability of motor, has reduced engine luggine and noise, has prolonged engine life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 cylinder; 2 bent axles; 3 crank throws; 4 compensating cylinders; 5 compensating cylinder pistons; 6 compensating cylinder crank throws; 7 compensating cylinder connecting rods; 8 supports; 9 bodies; 10 nuts.
