Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of balancing shafts, in particular to a balancing shaft mechanism. Background Art
[0002] Balance shafts can be divided into single balance shafts and double balance shafts. As the name implies, a single balance shaft uses a single balance shaft and works by gear transmission. The crankshaft rotates to drive the fixed balance shaft drive gear, balance shaft driven gear and balance shaft. The single balance shaft can balance the first-order vibration that accounts for a considerable proportion of the entire vibration, so that the vibration of the engine is significantly improved. Since the single balance shaft has a simple structure and occupies a small space, it is widely used in single-cylinder and small-displacement engines. The double balance shaft uses a chain drive to drive the two balance shafts to rotate. One of the balance shafts has the same speed as the engine, which can eliminate the first-order vibration of the engine; the speed of the other balance shaft is twice the engine speed, which can eliminate the second-order vibration of the engine, thereby achieving a more ideal vibration reduction effect. Since the double balance shaft has a more complex structure, high cost, and occupies a relatively large space in the engine, it is generally more commonly used in large-displacement vehicles. In addition, there is a double balance shaft arrangement, that is, the two balance shafts are arranged symmetrically with the center line of the cylinder, with opposite rotation directions and the same speed as the crankshaft speed, to balance the first-order reciprocating inertia force of the engine.
[0003] Currently, most balance shafts are manufactured directly according to fixed dimensions and do not have the function of adjustment. This increases the difficulty of assembly due to the inability to adjust. At the same time, the lack of adjustment function also leads to the single use of the balance shaft, which cannot be used for different situations.
