Description

Technical Field

[0001] The utility model relates to the technical field of elevator reduction boxes, in particular to an elevator reduction box body. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or actuator. It is widely used in modern machinery.

[0003] The existing elevator reduction box has a relatively small space, which leads to a slow cooling of the internal temperature. The high temperature will affect the braking effect of the reduction machine, causing the elevator to descend too fast or people to be injured, which is quite dangerous. The existing elevator reduction box lacks an emergency braking system for reduction machine failure. When the reduction machine fails, it cannot effectively prevent the elevator from crashing, which poses a safety hazard. Therefore, an elevator reduction box is proposed to address the above problems. Utility Model Content

The circulating pump is arranged to circulate the coolant through the water pipe, connecting pipe and circulating pipe inside the reducer. When the circulating coolant enters the water pipe part, it is blown directly to the water pipe through the air outlet of the cooling fan to perform physical cooling, so that the coolant is kept in the best state and the heat dissipation of the reducer is better, thereby solving the problem that the internal temperature of the existing elevator reducer is slow to cool down due to the relatively small space, and the high temperature will affect the braking effect of the reducer, causing the elevator to land too fast or people to be injured, which is more dangerous;

[0013] 2. In the utility model, by arranging components such as a reducer, a motor, a first gear, a second gear, a rotating shaft, a protective tube, a limiting groove, a motor connecting tube, a brake disc and a speed detector, the speed detector is first used to detect the speed of the motor connecting tube.
