Detailed Description
As shown in fig. 1, the electric steering engine based on ball worm gear transmission of the present embodiment includes a housing, a driving motor 101, a worm gear mechanism, and a steering engine output shaft 110.
The shell is a T-shaped shell and comprises an upper end cover 107 and a lower base 112; the upper bearing seat body and the lower bearing seat body of the tapered roller bearing are respectively and integrally formed on the upper end cover 107 and the lower base 112; the inside of the housing is also integrally formed with mechanical stops located on both sides of the sector worm wheel 109 of the worm gear mechanism, thereby limiting the rotation angle of the sector worm wheel 109. An angle potentiometer 106 used for monitoring the rotation angle of the steering engine output shaft 110 is arranged right above the steering engine output shaft 110 in the shell, so that the rotation angle of the steering engine output shaft 110 is monitored in real time.
The worm gear mechanism comprises a worm which is in transmission connection with a rotating shaft of the driving motor 101 through an elastic coupling 103 and a worm wheel which is connected with an output shaft 110 of the steering engine through a spline; the driving motor 101 is a direct-current brushless speed-reducing servo motor and is fixedly arranged in the shell through a motor base 102; the worm is a ball worm which is supported in the housing by a pair of tapered roller bearings (104, 108) arranged back to back; the rolling ball worm surrounds the rolling ball through the outer cover and is radially positioned for the rolling ball, the rolling ball enters the worm from the inner part and reversely and smoothly moves to the initial end after moving to the terminal end of the meshing area of the rolling ball and the worm wheel, and participates in the meshing of the worm wheel in the spiral groove on the surface of the worm again to complete the round and round movement, so that the sliding meshing of the traditional worm and gear mechanism is changed into rolling meshing, and the transmission efficiency is greatly improved. The worm wheel is a sector worm wheel 109, so that the worm wheel and worm mechanism improves the space utilization rate, reduces the space waste, makes the structure more compact and reduces the weight on the premise of ensuring that the transmission requirement is met; the power output shaft is a spline shaft which is supported in the shell through bearings (105, 111) and is matched and connected with a spline hole in the middle of the sector worm wheel 109.
The electric steering engine transmission path of the embodiment is as follows: the direct-current brushless speed-reducing servo motor drives the ball worm to rotate through the elastic coupling 103, and then drives the sector worm gear 109 to rotate, the sector worm gear 109 is connected with the steering engine output shaft 110 through a spline, and finally the steering engine output shaft 110 is driven to rotate.
