Abstract

The utility model relates to a speed reduction bearing which can reliably support shafts in the field of machinery and simultaneously obtain the goal of deceleration. The utility model is characterized in that a planetary wheel (4) is simultaneously engaged with a sun wheel (10) on an input inner ring (1) of a bearing and an inner gear (9), and a planet carrier (5) is connected with the planetary wheel (4) through a sliding bearing (8) and is fixed on an output inner ring (7) of a bearing, wherein, a bearing outer ring (3) is integrated with the inner gear (9). The utility model solves the defects of large dimension and heavy volume of the speed reducing mechanism in the existing machinery, and the speed reduction bearing which makes the speed reducing mechanism be combined in the bearing has compact conformation, small appearance dimension; utility model is widely and universally used in the occasion that the shaft requires support and deceleration in the machinery.

Description

Speed reduction bearing

The utility model is a kind of speed reduction bearing that uses for the mechanical field conduct reaches the deceleration purpose, and it can have reliable supporting to diaxon, and it can be transported to the rotating speed of an axle on another root axle with constant reduction speed ratio simultaneously.

Common bearing has radial ball bearing, garden post roller bearing, garden awl rolling bearing etc., though these bearings have reliable supporting to axle, but its function singleness, practicality gets up to have a lot of inconvenience, and all will slow down to prime mover basically in the machinery, for addressing this problem, all need at present the bigger speed reducer of a cover, and in the equipment, as a lot of speed outputs of needs, the changeable device of that speed is just more, just designs, installs and repair more trouble from equipment.

The purpose of this utility model is exactly to overcome above-mentioned deficiency, and reducing gear is combined among the bearing.It is a kind of deceleration purpose that both reached, and also can have the speed reduction bearing of reliable supporting to diaxon.

The utility model compact structure, operate steadily, output speed is stable, reduction speed ratio is big, can reach 1:8.Its external dimension are little, and are in light weight, and its rational modularity is used, and can satisfy the needs of a plurality of speed in the equipment, and institute takes up space for a short time, and it is widely used in the occasion that need support and slow down axle.

Fig. 1 is the sectional drawing according to the speed reduction bearing that the utility model proposes.

Describe in detail according to specific structural details and the working condition that the utility model proposes below in conjunction with Fig. 1.

Structure of the present utility model such as Fig. 1, bearing input inner ring (1) is an integral body with sun gear (10), bearing outer ring (3) is an overall structure with internal gear (9), have rolling bearing (6) to be connected between bearing input inner ring (1) and bearing output inner ring (7) and the bearing outer ring (3), planet wheel (4) meshes with internal gear (9) and sun gear (10) respectively.Sliding bearing (8) is housed in the planet wheel (4) is connected with planet carrier (5), planet carrier (5) is fixed on the bearing output inner ring (7).The endoporus of bearing input inner ring (1) and bearing output inner ring (7) has keyway, and it cooperated with being connected of axle is interference fit H7/p6 or transition fit H7/n6.There is fixing pin (11) fixing between bearing outer ring (3) and the cartridge housing, prevents to slide between bearing outer ring (3) and the cartridge housing.When input shaft drives bearing input inner ring (1) running, drive bearing output inner ring (7) running by sun gear (10), planet wheel (4), planet carrier (5), and a constant reduction speed ratio output is arranged.

Accompanying drawing 1 is described as follows:

1, bearing input inner ring 2, roller

3, bearing outer ring 4, planet wheel

5, planet carrier 6, rolling bearing

7, bearing output inner ring 8, sliding bearing

9, internal gear 10, sun gear

11, fixing pin

The utility model also can be used as the speedup bearing and uses, and when bearing output inner ring (7) connects input shaft, when bearing input inner ring (1) connects output shaft, can reach the purpose of speedup.

Material of the present utility model is a Bearing Steel, and its accuracy of manufacturing is implemented by NBS, and it can be made into the standard piece of all size and speed ratio, is widely used in the every field of machinery.

Claims
