    摘要： A driving mechanism for fastener driving machine, including a rotatable crank; a driving rack element rotatably installed on the crank, which comprises an engaging element, a support element and a driving rack; at least one fixed guide element. The support element and/or engaging element can move along the set trajectory. The present invention has a simple structure, a few parts and stable operation. When the crank rotates, the motion trajectory of the engaging element is straight or approximately O°, so as to reduce the kinetic friction force of load to the maximum extent, preventing wear problem, and guaranteeing constant direction of thrust on the impact unit in the course of compressed energy storage and low eccentric load in late stage, the quick release of driving mechanism is implemented, the operational stability and smoothness of impact unit are guaranteed, the work quality is upgraded.

    摘要： A gear wheel drive air compressor which is constructed as a piston compressor, the drive gear wheel of which on the air compressor crankshaft meshes with a gear wheel on the camshaft of the internal combustion engine. The inventive construction prevents the reverse acceleration of the camshaft drive gear wheel and minimizes the knocking pulse and noise in the mesh of the camshaft gear wheel in that the transmission ratio between the air compressor drive gear wheel and the camshaft gear wheel is embodied as a multiple load cycle of the camshaft drive torque, and at the same time the angular position of the air compressor crankshaft relative to the camshaft is fixed such that negative torque components of the air compressor crankshaft are eliminated by the overlapping of positive torque components of the camshaft. Furthermore, the air compressor drive gear wheel is arranged in alignment with the air compressor crankshaft.
