Abstract
The utility model discloses an input non-return structure of a speed reducer, which comprises an input flange and an input shaft, wherein a front roller bearing and a rear roller bearing are respectively arranged on the input shaft and between the input flange and the input shaft, a non-return device is arranged on the input shaft and between the front roller bearing and the rear roller bearing, a distance ring is arranged between the rear roller bearing and the non-return device, and a fastening piece is arranged on the input shaft and at the outer side edge of the rear roller bearing. The outer ring of the backstop is fixed by a flat key on the inner wall of the input flange, and the inner ring of the backstop is fixed by a key groove on the input shaft. The backstop can be directly arranged between the input flange and the input shaft, the axial dimension of the backstop is fixed by means of the distance ring and the fastening piece, and the input shaft drives the inner ring of the backstop to realize forward rotation and reverse backstop. The utility model has the advantages of simple and compact structure, convenient installation, low input cost and stable operation, and saves the installation space and the cost of the backstop.
Description
Technical Field
The utility model relates to a speed reducer, in particular to an input non-return structure of the speed reducer.
Background
The existing speed reducer cannot be directly added with a backstop, if the backstop is needed to be added, a bell-shaped support seat is needed to be additionally added, an input shaft is lengthened, and the problems that the backstop occupies a large space, is high in cost, inconvenient to install, long in input structure and the like exist.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides the input non-return structure of the speed reducer, which is simple and compact in structure and convenient to install.
The utility model aims at realizing the following technical scheme: the input non-return structure of the speed reducer comprises an input flange and an input shaft, wherein a front roller bearing and a rear roller bearing are respectively arranged on the input shaft and between the input flange and the input shaft, a non-return device is arranged on the input shaft and between the front roller bearing and the rear roller bearing, a distance ring is arranged between the rear roller bearing and the non-return device, and a fastening piece is arranged on the input shaft and at the outer side of the rear roller bearing.
The fastener is an assembly of a round nut and a round nut stop pad. The outer ring of the backstop is fixed by a flat key on the inner wall of the input flange, and the inner ring of the backstop is fixed by a key groove on the input shaft.
After the utility model is adopted, the backstop can be directly arranged between the input flange and the input shaft, other parts are not required to be additionally arranged, and the axial dimension of the backstop is fixed by means of the distance ring and the fastening piece (the round nut and the round nut stop pad). The key slot on the input shaft drives the inner ring of the backstop to realize forward rotation and reverse backstop. The utility model has the advantages of simple and compact structure, convenient installation, low input cost and stable operation. The installation space and the cost of the backstop are saved, and the appearance of the product is optimized.
Drawings
Fig. 1 is a schematic cross-sectional view of an input check structure of a speed reducer according to the present utility model.
Detailed Description
The utility model is described in further detail below with reference to the drawings and the detailed description.
Referring to fig. 1, the input non-return structure of the speed reducer of the present utility model comprises an input flange 7 (and a transparent cover 9), an input shaft 11, a front roller bearing 8 and a rear roller bearing 3 (both are tapered) respectively mounted on the input shaft 11 and between the input flange 7 and the input shaft 11, a non-return device 5 is mounted on the input shaft 11 and between the front roller bearing 8 and the rear roller bearing 3, a distance ring 4 is mounted between the rear roller bearing 3 and the non-return device 5, and a fastening member is mounted on the input shaft 11 and at the outer side of the rear roller bearing 3. An inner cavity 12 is arranged between the input flange 7 and the input shaft 11, and the front roller bearing 8, the rear roller bearing 3, the backstop 5, the distance ring 4 and the like are all arranged at the position of the inner cavity 12; an oil seal component 10 is arranged between the transparent cover 9 and the input shaft 11.
The fastener is an assembly of round nut 1 (back, left) and round nut stop pad 2 (front, right, close to rear roller bearing 3). The outer ring of the backstop 5 is fixed by a flat key 6 on the inner wall of the input flange, and the inner ring of the backstop is fixed by a key groove on the input shaft 11. The inner rings of the front roller bearing 8 and the rear roller bearing 3 are different in size, so that the front roller bearing is convenient to assemble, disassemble and maintain. The round nut and the round nut stop pad are used for replacing the elastic check ring for the shaft and the elastic check ring for the hole, and two front and rear roller bearings (conical) with different specifications are used for replacing the deep groove ball bearing, so that the axial bearing capacity of the input shaft is enhanced, and the input shaft is connected with the speed reducer. The front roller bearing and the rear roller bearing are lubricated by means of oil immersed in the lubricating oil in the gearbox of the speed reducer.
