Abstract

The disabled seat with the low-noise precise speed reducer is substantially characterized by comprising a driving mechanism, the driving mechanism comprises a driving shaft and a speed reducing shaft, the driving shaft is connected with a driving motor, and a first compound gear is further assembled on the driving shaft. The first compound gear is meshed with a second compound gear, the second compound gear is fixed to a speed reduction shaft, and the two ends of the speed reduction shaft are connected with large wheels of the electric wheelchair. The compound gear is characterized in that the compound gear comprises a gear body, and the gear body is provided with a hard tooth part and a soft tooth part adjacent to the hard tooth part. Gear teeth integrally formed with the gear body are annularly arranged on the hard tooth part, an axially expanded annular groove is formed in the soft tooth part, and a soft gear ring is assembled in the annular groove. Compared with an existing rigid meshing transmission technology of gears, transmission is carried out through meshing of the gear teeth and the soft gear ring, the low-speed transmission device is suitable for the field of low-speed transmission, noise is extremely low, and the abrasion rate is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of electric wheelchairs, and in particular relates to a disabled seat with a low-noise precision reducer. Background technique [0002] As a device to assist people with mobility disabilities and the disabled, electric wheelchairs are an essential means of transportation for the disabled. It has a wide range of applications and can be used in hospitals and homes. When in use, the handicapped person sits in the wheelchair and controls the forward, backward, turning and other actions of the wheelchair through the operation of the electric switch, which can be very convenient for the daily travel of the handicapped person. [0003] At present, the drive of the electric wheelchair is realized by a special motor device, which usually has three types: a gear motor, a crawler motor and a wheel hub motor. These motor devices also have some defects that need to be overcome when realizing the motor drive, such as: th...
