Problems solved by technology

In order not to be limited by this, to realize the two-point support of the output shaft, it is inevitable to lengthen the casing on the output side in the axial direction and form a span for the two-point support, or to take measures such as a casing with an extremely special molding structure. Causes problems such as increased cost, increased size, and increased weight

Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0023] FIG. 1 shows an example of a geared motor GM1 according to an embodiment of the present invention.

[0024] This geared motor GM1 is a device that integrates a motor M1 and an external engagement type parallel shaft gear reducer G1.

[0025] The motor M1 is provided with a motor shaft 14 rotatably supported by a pair of bearings (only the bearings 12 on the side of the parallel shaft gear reducer G1 are shown in the drawing). The front end of the motor shaft 14 is close to the inside of the parallel shaft gear reducer G1, and also serves as an input shaft of the parallel shaft gear reducer G1. Thus, the motor shaft 14 in this embodiment is appropriately referred to as the input shaft 14 for convenience.

[0026] The parallel shaft gear reduction mechanism G1 includes the input shaft 14 and the output shaft 16 arranged in parallel with the input shaft ...

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 ...
