Title:
DIRECT CURRENT MOTOR HAVING ONE-WAY BEARINGS
Document Type and Number:
WIPO Patent Application WO/2018/161645
Kind Code:
A1
Abstract:
A direct current motor having one-way bearings, which is mainly applicable in the driving of various electric products, the structure thereof comprising: a housing (4), a motor shaft (6), a front output shaft (1), a rear output shaft (10), and the like; by means of front and rear one-way bearings (3, 8), which are mounted having opposite directions of rotation and which are correspondingly additionally arranged between a front end of the motor shaft (6) and an inner end of the front output shaft (1) as well as between a rear end of the motor shaft (6) and an inner end of the rear output shaft (10), the present invention mainly achieves the following power output modes: the forward rotation of the motor shaft (6) drives the front output shaft (1) to synchronously rotate forward while the rear output shaft (10) remains stationary, or the reverse rotation of the motor shaft (6) drives the rear output shaft (10) to synchronously rotate in reverse while the front output shaft (1) remains stationary; which is to say that the output goal whereby the front and rear output shafts (1, 10) alternately rotate forward and in reverse is achieved by means of the forward and reverse rotation of the motor shaft (6); therefore, the improved direct current motor having one-way bearings may be better applied to various dust suction cleaner-type electric products which have said power output goal, while expanding the range of usage of direct current motors.
