Abstract
The utility model discloses a gear shaft sleeve for a motor of a mahjong machine, which comprises a shaft sleeve hole (1). The gear shaft sleeve is a closed U shape, is embedded on a motor cover board (2) and is positioned on the same plane with the inside of the motor cover board (2). The shaft sleeve hole (1) positioned at the center of the gear shaft sleeve is of a circular shape. The shaft sleeve hole (1) is matched with an output shaft of a gear. The gear shaft sleeve disclosed by the utility model is a closed U shape, is firmer in the assembling process and does not rotate along with the rotation of a bearing, so that the gear is ensured to stably operate and the motor has uniform speed, is stable and has low heat emission speed in the operating process.
Description
Technical field
The utility model relates to a kind of gear bush of motor, is specifically related to a kind of gear bush that is used for the dynamo-electric machine of mahjong.
Background technique
Gear is the mechanical component that meshes transmitting movement and power continuously; It is the vitals of the dynamo-electric machine of mahjong; Gear in the dynamo-electric machine of mahjong comprises actuation gear, mesomerism gear, driven gear; Gear is brought into play key effect in the electric-motor-driving process, various gear meshing degree affect steadily traveling at the uniform speed of motor.In the dynamo-electric machine of mahjong, mesomerism gear often is fixed on the motor cover plate through axle, and driven gear is connected on the bearing; The bearing housing that the output terminal of bearing passes on the cover plate carries out power transmission; If it is unreasonable that the bearing housing on the cover plate designs, bearing housing possibly rotate with bearing, influences the mesh degree between gear; Motor when operation noise greatly, not steadily, be prone to heating, the overall performance of the dynamo-electric machine of mahjong is exerted an influence.
The model utility content
The technical problem that the utility model will solve provide a kind of shaped design rationally, be easy to assemble, the dynamo-electric machine gear bush of mahjong simple in structure.
For solving the problems of the technologies described above; A kind of gear bush that is used for the dynamo-electric machine of mahjong of the utility model; Comprise axle sleeve hole, it is characterized in that: gear bush is the U-shaped that seals, and it is embedded on the motor cover plate and with motor cover plate inboard and is in same plane; The axle sleeve hole that is positioned at gear bush central authorities is for circular, is complementary with the output shaft of gear.
The said gear axle sleeve is PVC (PVC) material.
Take technique scheme; The beneficial effect that the utlity model has is: the gear bush of the utility model is the U-shaped that seals, rather than the conventional circle of using, thereby gear bush is more firm when assembling; Gear bush does not rotate with the rotation of bearing; Gear does not become flexible when operation, has guaranteed the mesh degree between gear, and gear operates steadily; The gear bush of the utility model is PVC (PVC) material, and axle sleeve is easy to moulding, low production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is used for the structural representation of the gear bush of the dynamo-electric machine of mahjong for the utility model is a kind of;
Fig. 2 is the structural representation of the dynamo-electric cover plate of mahjong of employing the utility model gear bush.
Embodiment
As shown in Figure 1, a kind of gear bush that is used for the dynamo-electric machine of mahjong comprises axle sleeve hole 1; Gear bush is the U-shaped that seals; It is embedded on the motor cover plate 2 and with motor cover plate 2 inboards and is in same plane, and the axle sleeve hole 1 that is positioned at gear bush central authorities is for circular, and axle sleeve hole 1 is complementary with the output shaft of gear.Gear bush is embedded on the motor cover plate 2; Gear is fixed on the bearing; The gear bush that the output terminal of bearing passes on the cover plate 2 carries out power and motion transmission, and the gear bush of the utility model is the U-shaped that seals, and gear bush is more firm when assembling; It does not rotate with the rotation of bearing, has guaranteed the smooth running of gear.
Claims (2)
1. gear bush that is used for the dynamo-electric machine of mahjong; Comprise axle sleeve hole (1); It is characterized in that: gear bush is the U-shaped that seals; It is embedded in, and motor cover plate (2) is gone up and be in same plane with motor cover plate (2) inboard, and the axle sleeve hole (1) that is positioned at gear bush central authorities is for circular, and the output shaft of itself and gear is complementary.
2. according to the described a kind of gear bush that is used for the dynamo-electric machine of mahjong of claim 1, it is characterized in that: gear bush is the PVC material.
