Problems solved by technology

[0005] The disadvantage of the existing technology is that the tubular motor is decelerated by multi-stage planetary gears, and the frictional resistance generated by the meshing rotation between the multi-stage planetary gears increases the output torque of the motor, increases the load of the motor, and easily causes planetary gear wear

Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] A tubular motor such as figure 1 with 2 As shown, it includes a casing 1, a base 12 is fixed on one side of the casing 1, an electric motor 10, a reduction mechanism 2, and an output shaft 3 are sequentially installed inside the casing 1, and the drive shaft 11 of the electric motor 10 is connected to the reduction mechanism 2 for driving the reduction mechanism 2 moves, thereby driving the output shaft 3 to rotate.

[0045] refer to figure 1 with 2 , the reduction mechanism 2 adopts a three-stage planetary gear 21 reduction mechanism 2, including a planetary gear 21, a sun gear 22, a planetary carrier 25 and a ring gear 23, and the planetary gear 21 is rotationally connected with the planetary carrier 25 through a shaft, and is simultaneously connected with the sun gear 22, The ring gear 23 meshes and there are four circumferentially distributed a...

Abstract

The invention discloses a tubular motor. The tubular motor includes a housing, an electric motor in a housing, Reduction mechanism and output shaft, the electric motor is connected with the output shaft through a reduction mechanism, The reduction mechanism comprises planetary gears, Sun gear, planet carrier and ring gear, At that two end of the gear ring are connected with fixed seats, and through the circumferential rotation of the fixed seat limit ring gear, An oil storage cavity is arranged inside the fixed seat, a plurality of oil outlet holes are arranged on the end face of the fixed seat facing the gear ring, a seal member which opens or closes the oil outlet hole is arranged on the fixed seat one by one corresponding to the oil outlet hole, a control system is connected between theseal member and the power supply, and the seal member is controlled to seal or open the oil outlet hole by the control system; The tubular motor has the advantages of reducing the friction resistancebetween the planetary gears, reducing the load of the electric motor and prolonging the service life of the tubular motor.

Description

technical field [0001] The invention relates to a motor, in particular to a tubular motor. Background technique [0002] Tubular motors are widely used in various electric lift doors and windows, sunshade systems, projection screens, etc., including external motor tubes, motor assemblies, brake assemblies, deceleration assemblies, and stroke control assemblies. Press the lift switch when the power is on Control the rotation of the motor assembly to drive the rotation of the motor tube through the deceleration output of the deceleration assembly, and the rotation of the motor tube and the rotation of the electric outer tube realize the lifting of doors, windows or projection screens. [0003] The authorized announcement number is CN201319544, and the application date is December 15, 2008. The Chinese patent discloses a tubular motor, including a motor, a planetary gear reduction mechanism, an output shaft, and a fixed shaft assembly. The stroke control mechanism is installed ...
