Description

Technical Field

[0001] The utility model relates to the technical field of reducers, and in particular to a reducer suitable for AGV. Background Art

[0002] In the existing drive mechanism for AGV, the power of the drive motor is generally transmitted to the drive wheel through a reducer. The reducers currently available on the market are mainly composed of gear transmission, worm transmission, gears, and worm transmission enclosed in a rigid shell. They play the role of matching the speed and transmitting torque between the prime mover and the actuator. They can not only change the transmission direction, but also increase the output torque while reducing the speed.

[0003] When the existing reducer is connected to the AVG, it is only connected to the AVG by bolts and the output shaft. When it shakes or is hit during use, the connection is prone to loosening, which leads to poor stability of the reducer. Summary of the invention

[0010] A further improvement of the technical solution of the utility model is that: the output shaft is provided with an input shaft bearing, a planetary arm bearing, a planetary gear, an output shaft bearing and an output shaft oil seal; the output shaft is fixedly connected with a planetary arm frame, and the two sides of the planetary arm frame are extended outward to form a cage shape outside the planetary gear, thereby increasing the supporting force and ensuring that the reducer can work stably under high load conditions.

[0011] A further improvement of the technical solution of the utility model is that the connecting mechanism includes a connecting frame, the connecting frame is fixedly connected to the reducer body, a positioning rod is fixedly connected to the connecting frame and the reducer body, and an anti-slip pad is fixedly connected to the outer surface of the positioning rod, which increases friction and thus improves the firmness of the connection.

[0012] A further improvement of the technical solution of the utility model is that: the internal thread of the connecting frame is connected with a first bolt, one end of the first bolt is fixedly connected to a limiting plate, a limiting rod is inserted into the interior of the connecting frame, and the limiting rod passes through the first bolt, and a second bolt is arranged at one end of the limiting rod, and the limiting rod passes through the connecting frame and the first bolt, thereby increasing the tightness of the connection between the first bolt and the connecting frame.

[0013] A further improvement of the technical solution of the utility model is that a nut is fixedly connected to one side of the connecting frame, and the second bolt at the tail end of the limiting rod is threadedly connected to the inside of the nut. After the tail end of the limiting rod is screwed into the nut, the limiting rod is fixed in the connecting frame.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] The utility model provides a reducer suitable for AGV, wherein a positioning rod and an anti-skid pad are inserted into a connecting hole of an AVG, the anti-skid pad plays a role in increasing friction, thereby preliminarily fixing the connecting position, and then the output shaft is inserted into the AVG, so that the reducer and the AVG are in contact with each other, a first bolt is screwed into a connecting frame and the AVG, so that a limiting plate and the connecting frame are in contact with each other, and then the limiting rod is inserted into the connecting frame and passes through the first bolt at the same time, and the limiting rod is rotated so that the bolt at the rear end of the limiting rod enters the nut, so that the connection strength between the reducer and the AVG can be improved, thereby improving the stability of the reducer when in use.

[0016] The utility model provides a reducer suitable for AGV, which starts the electric rotating rod to drive the heat dissipation fan blades to rotate, thereby blowing wind into the reducer body to dissipate heat for the reducer, and then starts the refrigerator to cool the cooling water in the condenser tube, and the cold air is emitted outwards through the ventilation holes. The emitted cold air cools the wind, which can reduce the temperature inside the reducer again, thereby improving the heat dissipation effect of the reducer, thereby achieving the purpose of extending the service life of the reducer.
