Problems solved by technology
[0002] At present, many mechanical processing equipment are equipped with a gear transmission mechanism, that is, power transmission is realized through two mutually meshing gears, but due to the existence of processing and installation errors and the wear of the gears during operation, the backlash of the gear teeth will be caused. Increase, which greatly affects the transmission accuracy of the meshing gear, and then affects the processing accuracy and processing quality of the entire equipment

The invention discloses a cylindrical gear transmission mechanism for adjusting tooth backlash by a single screw. The cylindrical gear transmission mechanism comprises a first transmission shaft, a second transmission shaft, a first transmission gear and a second transmission gear, wherein the first transmission gear is engaged with the second transmission gear in a transmission manner, the first transmission gear is of an integral structure, the second transmission gear is formed by a gear A and a gear B in parallel, the gear A is fixed on the second transmission shaft, a cylindrical lug boss is coaxially formed on one end surface of the gear A in the axial direction in an extending manner, the gear B sleeves on the cylindrical lug boss, a plurality of compression screws are axially fixed between the gear A and the gear B, a shifting pin is also axially arranged between the gear A and the gear B in a penetrating manner, and the shifting pin and the compression screws are uniformly distributed along the circumference of the central axis of the gear A. By adopting the structure, the shifting pin can be driven by adjusting the screw to rotate along the central axis of the second transmission shaft, so that the gear B is driven to rotate for a micro angle relative to the gear A, and the adjustment of the tooth backlash of the gear can be realized.
Description
technical field [0001] The invention relates to a gear transmission mechanism, in particular to a cylindrical gear transmission mechanism capable of adjusting the tooth side clearance through a single screw rod. Background technique [0002] At present, many mechanical processing equipment are equipped with a gear transmission mechanism, that is, power transmission is realized through two mutually meshing gears, but due to the existence of processing and installation errors and the wear of the gears during operation, the backlash of the gear teeth will be caused. Increase, which will greatly affect the transmission accuracy of the meshing gear, and then affect the processing accuracy and quality of the entire equipment. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a cylindrical gear transmission mechanism capable of adjusting the backlash of the gear teeth through a single screw rod. By adjusting the backlas...
