Abstract
The utility model relates to a motor reduction gearbox for a mahjong machine, which belongs to the technical field of production manufacturing of motors, and comprises a box body and a box cover, wherein a plurality of reduction gears are arranged in the box body, and a gear shaft of the reduction gear, the box body and the box cover are rotatably supported by a porous bearing. The motor reduction gearbox for the mahjong machine has lower manufacturing cost and less noise, and solves the problem in a prior motor reduction gearbox for a mahjong machine that the noise during the operation process is bigger and the like.
Description
Technical field
The utility model relates to a kind of mahjong machine motor reduction gearbox, belongs to the technical field that motor is manufactured.
Technical background
The motor that is used to finish each action in the automatic mahjong-playing machine is more, and correspondingly motor reduction gearbox is also more, and the noise that produces when a plurality of motors of mahjong machine turn round simultaneously is bigger, and one of main source of noise is promptly from motor reduction gearbox.In the prior art, the ball bearings that adopt rotate support more between the gear shaft of the reduction gear of motor reduction gearbox and casing and the case lid, and when speed reducer turned round, the ball between the ball bearing Internal and external cycle rolls will produce bigger noise.
Summary of the invention
The utility model purpose is to provide a kind of manufacture cost lower, and the mahjong machine motor reduction gearbox that noise is less has solved problems such as the noise that produces in the operation process of existing mahjong machine with the motor reduction gearbox existence is bigger.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises casing and case lid, is provided with some reduction gear in the casing, all adopts the oil-impregnated bearing rotation to support between the gear shaft of described reduction gear and casing and the case lid.Because oil-impregnated bearing possesses characteristics such as noise is little, cost of production is low, therefore, the utility model will all adopt the oil-impregnated bearing rotation to support between the gear shaft of reduction gear and speed reducer and the case lid, the noise in the mahjong machine operation process can be reduced greatly, the manufacture cost of mahjong machine can also be reduced simultaneously to a certain extent.
As preferably, be respectively equipped with the bearing hole that matches with oil-impregnated bearing on described casing and the case lid, the outer end of described oil-impregnated bearing is provided with ring-shaped step, and described ring-shaped step contacts with the end of bearing hole.Wherein, the ring-shaped step location will be adopted between the bearing hole of oil-impregnated bearing and casing and case lid, fixing between oil-impregnated bearing and casing and the case lid can be strengthened.
As preferably, adopt close-fitting to install between described reduction gear and the gear shaft.
Therefore, it is lower to the utlity model has manufacture cost, characteristics such as noise is less.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, comprise casing 1 and case lid 2, be provided with a plurality of reduction gear 3 in the casing 1, close-fitting between reduction gear 3 and the gear shaft 4 all adopts oil-impregnated bearing 5 rotations to support between gear shaft 4 and casing 1 and the case lid 2.Be respectively equipped with the bearing hole 6 that matches with oil-impregnated bearing 5 on casing 1 and the case lid 2, the outer end of oil-impregnated bearing 5 is provided with ring-shaped step 7, and ring-shaped step 7 contacts with the end of bearing hole 6.
With all adopting the oil-impregnated bearing rotation to support between the gear shaft of reduction gear and speed reducer and the case lid, can reduce the noise in the mahjong machine operation process greatly, can also reduce the manufacture cost of mahjong machine simultaneously to a certain extent.
