Vertical deceleration direct current permanent magnet motor

Abstract

The invention relates to a vertical deceleration direct current permanent magnet motor, which resolves the problem that the existing motor matched with a food processor in use is large in volume, high in mass, small in torque, high in temperature rise and high in cost. The motor comprises a vertical motor and a reduction box which are integrated. The reduction box comprises an inner gear ring. Three first-grade planet gears, a planet support, three second-grade planet gears and an output shaft of the reduction box are arranged in the inner gear ring. The first-grade planet gears and the second-grade planet gears all adopt non-equidistance meshing structure and are respectively meshed with the inner gear ring. Two first-grade planet gears are meshed with an output shaft of the motor, two second-grade planet gears are meshed with a transmission shaft, and inner teeth of the inner gear ring adopt the unsymmetrical non-involute helical tooth structure. The vertical deceleration direct current permanent magnet motor is large in transmission speed ratio and small in size, adopts the vertical direct current permanent magnet motor structure which is small in size, light in quality and small in noise, reduces manufacture cost, and is capable of conducting a spark test of a commutator.

Description

[0001] technical field [0002] The invention relates to a motor, in particular to a vertical decelerating direct-current permanent magnet motor matched with a food processor with small volume, light weight, large torque and low temperature rise. Background technique [0003] The existing DC permanent magnet motors for domestic food processors generally adopt worm gear and worm variable speed structure, the type is horizontal installation, the output shaft is connected by an inner hexagon, and the torque is 10N·M. For sugarcane juice extraction, because the material of the worm wheel is nylon, it will be damaged due to torque overload. At the same time, the horizontal installation structure makes the juicer bulky and bulky, and the appearance is not beautiful. At the same time, it cannot realize the functions of noodle rolling and meat grinding. [0004] Food processors with torque >10N·M currently use induction motors and multi-stage gear transmission structures in China...
