Utility model content

Problem to be solved in the utility model is to provide a kind of motor reducer integrated actuating unit, has structure Simply, the advantages of installation occupies little space comprising output motor and reduction gearbox, the output motor include from motor front end cover The motor shaft of middle stretching, the reduction gearbox include cabinet, and the cabinet is equipped with annular flange, institute in face of the side of the drive end bearing bracket The end face and the drive end bearing bracket for stating annular flange are fixed, to motor shaft is enclosed in the annular flange, the convex annular The driven input gear of level-one being sequentially connected with cabinet internal gear wheel group is equipped in edge, the motor shaft head is equipped with and described one The level-one driving gear of the driven input gear engagement of grade, the driving gear set can be by the power vertical output of motor shaft to institute It states on the output shaft of reduction gearbox, realizes the advantages of structure is simple, and installation occupies little space.

As a kind of preferred embodiment of the utility model, the driven input gear of level-one is set to second level active conical tooth On wheel shaft, the second level driving tapered gear shaft passes through cabinet and protrudes on the inside of reduction gearbox.

As a kind of preferred embodiment of the utility model, end of the second level driving tapered gear shaft on the inside of reduction gearbox Head place is equipped with angular wheel, the angular wheel and the intracorporal second level driven wheel of differential Vertical Meshing of case, and the second level is from mantle Geared sleeve is set on three-level driving gear shaft.

As a kind of preferred embodiment of the utility model, the three-level driving gear shaft is fixed on vertically by bearing In cabinet, the axis body of the three-level driving gear shaft is engaged with three-level driven gear straight-tooth, and the three-level driven gear is sheathed on On output shaft, output shaft is stretched out from cabinet.

The utility model by by motor with it is reducer integrated, compared to it is traditional using shaft joint by motor and reduction gearbox Connected mode has small in size, the simple advantage of structure, hangs down additionally, due to motor output shaft and reduction gearbox output shaft in axial Straight installation, the horizontal space that when installation occupies is small, can preferably apply in the narrow environments such as escalator.

Detailed description of the invention

The utility model is further described below in conjunction with attached drawing:

Fig. 1 is the transverse sectional view of the utility model；

Fig. 2 is the longitudinal sectional view of the utility model；

Fig. 3 is stereoscopic schematic diagram when the utility model is assembled in jacking system.

Wherein: 1- output motor, 2- motor shaft, 3- level-one driving gear, the driven input gear of 4- level-one, 5- second level master Dynamic bevel gear axis, 6- cabinet, 7- second level driven wheel of differential, 8- three-level driving gear shaft, 9- three-level driven gear, 10- output Axis.

Specific embodiment

The utility model is further elaborated below by way of specific embodiment:

As depicted in figs. 1 and 2, a kind of motor reducer integrated actuating unit, including output motor 1 and deceleration Case, motor shaft 2 are stretched out from the drive end bearing bracket of output motor 1, which includes cabinet 6, and cabinet 6 is in face of motor front end face Side is equipped with annular flange, is fixed to each other between the end face and drive end bearing bracket of annular flange, motor shaft 2 is wrapped in the annular flange Interior, motor shaft head is equipped with key, and level-one driving gear 3 is fixed on motor shaft head by key, is additionally provided in annular flange and level-one master The driven input gear 4 of level-one of 3 straight-tooth of moving gear engagement, the driven input gear 4 of the level-one are set to second level driving tapered gear shaft 5 On, which passes through cabinet 6 and protrudes into reduction gearbox inboard, which is being located at cabinet 6 The end of internal side is equipped with angular wheel, the angular wheel and 7 Vertical Meshing of second level driven wheel of differential in cabinet 6, The second level driven wheel of differential 7 is set on three-level driving gear shaft 8, which is fixed on vertically by bearing In cabinet, the axis body of the three-level driving gear shaft 8 is engaged with 9 straight-tooth of three-level driven gear, and three-level driven gear 9 is set in output On axis 10, output shaft 10 is stretched out from cabinet 6 for driving walking mechanism, thus will be electric by a series of driving gear set The output power of arbor 2 is through speed varying back shaft in vertical output to reduction gearbox output shaft 10, and the utility model is by by motor With it is reducer integrated, compared to traditional in such a way that motor is connected by shaft joint with reduction gearbox, have it is small in size, structure letter Single advantage, in addition as shown in figure 3, since motor output shaft and reduction gearbox output shaft are in axially vertical installation, when installation, is occupied Horizontal space it is smaller, can preferably be applied in the narrow environments such as such as escalator.

But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to Variation, the modification of the upper embodiment will all be fallen in the Claims scope of the utility model.
