Abstract

The invention relates to a gapless transmission device of a numerical control contour grinder, belonging to the field of grinder parts. The prior transmission devices of non-circular inner-aperture grinders have the defects of large space occupation, high cost, large energy consumption, poor precision, short service life and incapability of rotating forward and backward. The invention adopts a gearbox form comprising a gearbox body, a box cover, a motor and an encoder, wherein a rotary shaft used as a driving shaft and a main shaft used as a driven shaft are arranged on the box body; the rotary shaft is fixedly sheathed with a small gear, and the main shaft is sheathed with two large gears engaged with the small gear, wherein one large gear is fixed together with the main shaft, and the other is movably sheathed on the main shaft. The tooth surfaces of the two large gears are staggered by an angle staggering mechanism and are closely attached to the tooth surface of the small gear. Theencoder is connected with the main shaft through a shaft coupling and is connected with a numerical control system through a signal wire. The invention has stable transmission and favorable precisionkeeping and can rotate forward and backward continuously.

Description

technical field [0001] The invention belongs to the field of grinding machine components, and in particular relates to a gapless transmission device of a numerically controlled curve grinding machine. Background technique [0002] In order to achieve the machining accuracy of the contour of the parts, there are currently two ways for the power transmission device of the non-circular inner hole CNC grinding machine. One is to use a high-power servo motor to directly drive the spindle to rotate, so that it can also be achieved at a lower speed. Certain precision requirements are required, but high-power servo motors have relatively large dimensions, resulting in a large footprint, high cost, and high energy consumption. The other is to achieve high torque through high-precision worm gear deceleration, and use the friction plate damping method to make the transmission close to the side of the worm wheel to eliminate the gap caused by the manufacturing error of the worm gear pai...
