Transmission gapless force transmission gearbox

Abstract

The invention discloses a transmission gapless force transmission gearbox; a first input shaft is rotationally connected into a shell, a first bevel gear is arranged on the first input shaft, and a gear gap adjusting piece is arranged on the left side of the first input shaft; the gear gap adjusting piece comprises a rotating shaft rotationally connected to the shell, a second bevel gear is fixed to the rotating shaft, and a pressing spring used for pressing the tooth face of the second bevel gear on the tooth face of the first bevel gear in the axial direction of the rotating shaft is arranged at the side end of the rotating shaft; and the right side of the first input shaft is provided with a force transmission shaft rod rotationally connected into the shell, a third bevel gear is fixed to the force transmission shaft rod, the side of the force transmission shaft rod is provided with a first output shaft rotationally connected to the shell, a fourth bevel gear is fixed to the first output shaft, and a fifth bevel gear meshed with the fourth bevel gear is fixed to the force transmission shaft rod. The transmission gapless force transmission gearbox is ingenious and reasonable in structural design, gapless force transmission and shaking between gears of the gearbox can be avoided, the machining precision of high, precise and sharp products can be high, and the gearbox is worthy of application and popularization.

Description

technical field [0001] The invention relates to a gearbox, in particular to a transmission gapless force transmission gearbox. Background technique [0002] The gearbox is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. Mechanisms play the role of matching speed and transmitting torque, and are widely used in modern machinery. [0003] Due to the limitation of processing accuracy and assembly accuracy of traditional gearboxes, there will be small gaps between gears, and running errors will occur during operation (such as running high-precision equipment for mobile processing). When the gearbox is running, it will also vibrate the transmission itself, which will have a great impact on the processing accuracy of high-precision equipment, resulting in an increase in the defective rate, which is not...

Problems solved by technology

[0003] Due to the limitation of processing accuracy and assembly accuracy of traditional gearboxes, there will be small gaps between gears, and running errors will occur during operation (such as running high-precision equipment for mobile processing). When the gearbox is running, it will also vibrate the transmission itself, which will have a great impact on the processing accuracy of high-precision equipment, resulting in an increase in the rate of defective products, which is not conducive to the production and processing of high-precision, sharp products.
