Clearance elimination gear and method with torque measurement function and for numerical-control equipment

Abstract

The invention discloses a clearance elimination gear and method with a torque measurement function and for numerical-control equipment. The clearance elimination method relates to the clearance elimination gear and an adjustment device. The clearance elimination gear comprises a rear gear body, a front gear body and a three-leg sleeve. A mounting groove is formed in the middle of the front gear body. According to the clearance elimination gear and method with the torque measurement function and for the numerical-control equipment, the torque between the two gear bodies can be adjusted within awide range, and the numerical value of the torque can be displayed, so that the application of clearance elimination gears with various diameters is facilitated; repeated calculation of the spring force and repeated manufacturing of springs of various specifications are not needed, and data can be fed back, so that study on straight-tooth clearance elimination gears and popularization of the industrial standard are facilitated; compared with tension springs, compression springs can be adjusted within a larger range in a relative space; the structure is compact, so that the problem that the torque cannot be adjusted within a wide range in a narrow annular area is solved; and the specific numerical value of the torque can be obtained through the cooperation of the adjustment device and a digital-display torque spanner, and the purpose of data feedback is realized.

Description

technical field [0001] The invention relates to the technical field of gear anti-backlash, in particular to a torque-measurable anti-backlash gear on a numerical control device and an anti-backlash method. Background technique [0002] The gear transmission is a relatively common transmission device, which can realize the torque matching between the servo motor and the actuator, and can also realize the conversion of linear motion and rotary motion. There are various transmission errors in the servo system of the gear transmission chain, and these errors can be roughly divided into angular transmission errors and linear transmission errors. The above-mentioned types of transmission errors have a great relationship with the existence of backlash in the gear transmission process. Therefore, in the occasion where high-precision position information or angle information needs to be transmitted, an appropriate error adjustment method must be adopted to control the amount of erro...

Problems solved by technology

That is to say, a tension spring can only match a backlash-removing gear with one diameter. As long as the diameter of the gear changes, the spring tension mechanism of the backlash-removing gear must be redesigned and manufactured. Customized, unable to form industry manufacturing standards of various specifications, low practicability, high cost of use
