Embodiment
1 and 2 as can be known with reference to the accompanying drawings, the utility model is specifically related to a kind of automobile brake test bed motor special reductor, this device is used for guarantee and the detection of automobile, its concrete structure comprises motor and deceleration device, motor and deceleration device are packaged as a whole, and electric machine main shaft 5 is as the one-level power transmission shaft of deceleration device.Deceleration device is double reduction, comprises power transmission shaft 4, power output shaft 6 and reduction gearing, and power transmission shaft 4 be arranged power output shaft 6 and the coaxial setting of electric machine main shaft in parallel with electric machine main shaft 5.Motor in this structure adopts 6-pole motor 3, and it mainly is made up of electric machine main shaft 5 outside rotor and the stator that is fixed on the body, and stator is centered around the rotor outside, and motor one side is provided with tail-hood.
Said structure is according to instructions for use, and installation environment requires overall dimension little, and output torque is big, and motor and deceleration device are integrated; Motor in this structure adopts 6-pole motor 3, replaces four utmost point motors of original structure, and when the identical and power output of electric machine stand model was identical, 6-pole motor and four utmost point rotating speed of motor were than being 2:3, and the 6-pole motor output speed reduces.Use 6-pole motor 3, if the output speed of reductor is constant, the speed reducing ratio of reductor just can correspondingly dwindle 2/3 so, and the size of reductor just can correspondingly reduce.
The motor that the original motor reductor uses is four utmost point motors, the motor output speed is 1440 rev/mins, the 6-pole motor output speed is 960 rev/mins, and the reductor output speed to remain unchanged be 54 rev/mins, therefore the reductor speed reducing ratio is reduced to 17.78 by 26.67, thereby guarantee that the reductor output speed is constant, but the overload factor of reductor has increased; 6-pole motor is mainly that with the difference of four utmost point motors rotating speed is different, is respectively 960rpm and 1440rpm, and output torque 6-pole motor is bigger than four utmost point motors.
Existing designed motor reductor overall dimension remains unchanged, and output speed is constant, reduces speed reducing ratio, increases module.Keep having improved the overload factor of reductor under the constant situation of former reductor output torque, the reliability of motor reducer is improved greatly.Its kind has 11kw, 15kw, 18kw reductor, and the output peak torque reaches 4300N.m, 5400N.m, 6300N.m respectively; Output speed 54rpm.
Reduction gearing comprise the one-level reduction gearing to 1 and double-reduction gear 2, two pairs of gears are the helical gear transmission.Deceleration device adopts double reduction, utilizes helical gear to replace the spur gear transmission, reduces rotational noise, and secondary gear is hit greatly during owing to use, therefore increases secondary travelling gear modulus, improves overload factor.
In addition, the motor part, according to the running operating mode motor is retrofited, motor and deceleration device are that one is installed simultaneously, overload is used during motor rotation, and in order to reduce the reductor volume, motor designs according to squirrel-cage threephase asynchronous machine 6-pole motor during the design motor, reduce the gearratio of reductor, thereby reduce the deceleration device volume; Because the motor rotation operating mode is intermittent running, and is less demanding to the heat radiation of motor, during design, in order to shorten motor size, abandons the radiator portion fan design.Demarcate needs in order to satisfy brake platform, the motor tail-hood is designed to band and supports, and rolling bearing units can be installed, in order to support reductor.
The structural representation of the utility model when concrete the use, can be with reference to the accompanying drawings 3 and 4, motor reducer is fixed on the detection platform, the one end supports by rolling bearing units 8, output drives a cylinder 10 by power output shaft 6 and rotates, be arranged in parallel at two cylinders 10, formed the automobile brake detection platform, by the motor output transducer 9 is set and detects by the next automobile braking force of cylinder 10 transmission.
The utility model is used for automobile brake perfrmance and detects, and satisfies under the prerequisite of installation environment, reduces overall dimensions as far as possible, guarantees that output speed is constant, reduces speed reducing ratio, increases module.
