Description

Technical field [0001] The invention involves the field of stereo garage technology, especially a three -dimensional garage lifting mechanism. Background technique [0002] The deceleration motor is a combination of motor and reducer.At home and abroad, there are generally used reducer motors that are generally used by lifting a three -dimensional garage lift mechanism. The motor uses a cylindrical mouse cage rotor, a braking part, and an independent coaxial electromagnetic brake; the reducer part is used.Essence [0003] Its advantages are: simple design and mature craftsmanship.The brake brake response time is short and the positioning is accurate. [0004] The disadvantage is: [0005] ① There is no anti -falling function during the lifting operation.When the motor fails during operation, the vehicle will fall into a flying car accident. [0006] ② Great inertia impact during starting and braking. [0007] ③ The transmission efficiency is low.In the motor part, the brakes use ...

AI Technical Summary

Problems solved by technology

[0005]①There is no anti-drop function during the lifting operation

When the motor fails during operation, it will cause a load drop and runaway accident

[0006]② Large inertial impact during start-up and braking

[0007]③Low transmission efficiency

Has not yet met the requirements of high-efficiency motors

[0008]④ Huge structure

The motor part, due to the use of independent electromagnetic brakes, increases the structural complexity and large volume; the reducer part, due to the use of traditional cylindrical gear fixed shaft gear train transmission, the single-stage gear pair transmission ratio is small, so usually three or more stages are used transmission, resulting in bulky

[0009]⑤ High failure rate

Since the motor brake must be equipped with a step-down rectification circuit, it usually becomes a high-incidence point of failure; the reducer part, affected by many factors such as gear processing and bearing lubrication, is prone to failures such as overheating, rapid wear, high-speed gear grinding, and oil leakage.

[0010]⑥ Difficulty adjusting

After the deceleration motor runs for a period of time, the friction plate of the brake will wear out, and manual intervention compensation adjustment is necessary. The adjustment of the brake of this kind of motor is very complicated, and it must be debugged by professionally trained maintenance personnel with special tools such as feeler gauge. Increased maintenance difficulty and cost for garage users

[0011]⑦High manufacturing cost and complex process

[0014]According to the search, there is no patent application identical to the present invention at home and abroad
