Abstract

The invention provides a low cost structure forms outside the correspondence two-pole to meet meshes is the parallel axis gear reduces inspiring machine. States the shell in front (30) before nearby central committee, causes with first to state shell (30) the main body (32) the independent intermediate plate (34) supports states the output shaft (30) the main body (32) center before, simultaneously, uses this intermediate plate (34) supports states the output shaft (16) a nose. And, with first states the input axis (motor axis) (14) and the output shaft (16) parallel disposes the intermediate shaft (18). In addition, in the input axis (14) and the intermediate shaft (18) between, this intermediate shaft (18) and first states the output shaft (16) between, altogether forms outside two levels to meet gnaws the suitable parallel axis gear reduction gear, and is front concentriily states output shaft (16) the axis core (O2) and first states the input axis (14) the axis core (O1).

Description

technical field

[0001] The invention relates to an external meshing type parallel shaft gear reducer and a gear transmission motor integrating the reducer and the motor. Background technique

[0002] The parallel shaft gear reduction mechanism is a mechanism that decelerates the rotation of the shaft on which the pinion is assembled and outputs the output from the shaft on which the gear is assembled via the pinion and the gear respectively assembled on the shaft arranged in parallel. Because of its low cost, it has been widely used in the past as a representative reduction mechanism.

[0003] Among the pinion gears and gears constituting the parallel axis gear reduction mechanism, there are spur gears whose tooth direction is straight parallel to the axis, or helical gears whose tooth direction is inclined relative to the axis, and so-called involutes are usually used. Tooth shape.

[0004] Parallel shaft gear reduction mechanism, in principle, can increase the reduction ...
