Fast door motor

Abstract

A fast door motor comprises a motor body, a main shaft is arranged on the motor body, a shell is arranged on one side of the motor body, the output end of the main shaft is connected with an input shaft, the output end of the input shaft is connected with a first gear, the first gear is meshed with a second gear, and the second gear is connected with an output shaft. A transmission gear set with the adjustable transmission ratio is meshed between the first gear and the second gear. The device has the beneficial effects that the transmission ratio is adjusted through the transmission gear set capable of adjusting the transmission ratio, a proper transmission ratio structure can be selected according to the resistance requirement of the fast door, the transmission efficiency is high, operation is stable and reliable, the impact resistance is high, the service life is long, and the device can be matched with fast doors with different transmission ratio requirements for use; the effect of matching diversification is achieved, the mode that an existing fast door can only use a fixed fast door motor is changed, and the motor can be applied to different fast doors and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a fast door motor. Background technique [0002] High-speed shutter doors are also called high-speed doors. High-speed doors have many functions such as heat preservation, cold preservation, insect resistance, wind resistance, dust resistance, sound insulation, fire prevention, odor prevention, and lighting. They are widely used in food, chemical, textile, electronics, supermarkets, refrigeration, Various places such as logistics and warehousing can meet high-performance logistics and clean places, and save energy, automatically shut down at high speed, improve operating efficiency, and create a better operating environment. [0003] Fast door technology has developed rapidly in the development of its extended product industry and has a broad market, with a very promising development prospect. High-speed fast doors and high-speed doors are favored by customers for their convenien...

AI Technical Summary

Problems solved by technology

[0004] At present, the fast door motors commonly used in the fast doors on the market are usually directly connected to the speed reducer on the fast door motor in structure, and the fast door motor and the speed reducer form a fixed structure. The disadvantage is that the deceleration transmission ratio is fixed, and the fast door can only use a fixed fast door motor, which has a narrow application range and cannot achieve diversified matching functions. Moreover, in the long-term use of the fast door, the fast door needs to be increased due to various loss factors. When the deceleration transmission ratio is increased or decreased, the fixed fast door motor cannot meet the requirements of use, which makes it difficult to open the fast door, or it is easy to cause accidental injury if it is opened too fast, and the actual application effect is not ideal
