Same direction cone double-gear box adopting flexible shaft coupler

Abstract

The invention relates to a same direction cone double-gear box adopting a flexible shaft coupler. An input shaft, a gear shaft, a first transmission shaft and a second transmission shaft are installedin a transmission box body of a box body in parallel; a small gear is installed on the gear shaft, and is in engaged connection with a gear of the input shaft; the gear shaft is in engaged connectionwith a large gear installed on the first transmission shaft which is provided with a first transition gear; the first transition gear is in engaged connection with a second transition gear installedon the second transmission shaft in a transmission manner; an output long shaft, a third transmission shaft and an output short shaft are installed in a distributing box body of the box body; the first transmission shaft and the third transmission shaft are connected through the flexible shaft coupler; the output long shaft is connected with the second transmission shaft through an involute spline; a left-handed distribution gear is installed on the third transmission shaft; a right-handed distribution gear is installed on the output short shaft; and common cylindrical spiral gear structures are adopted for the left-handed and right-handed distribution gears. According to the same direction cone double-gear box adopting the flexible shaft coupler, the first transmission shaft and the thirdtransmission shaft are connected through the flexible shaft coupler, the installing space is reduced, the torque is high, noise is low, and machining and installing are convenient.

Description

technical field

[0001] The invention relates to a gear box used in the plastic extrusion industry, in particular to a co-rotating bevel double gear box. Background technique

[0002] The co-rotating bevel double gearbox is an important component widely used in the plastic extrusion industry. Its main function is to reduce speed and change the transmission direction. The distribution gear of the existing co-rotating bevel double gearbox has a small bearing torque and is easy to be damaged. Therefore, it is necessary to use a flexible shaft coupling to form the included angle, and use a standard cylindrical gear to replace the cylindrical bevel gear used on the traditional bevel double. The advantages of the change are high torque, low noise, and small footprint. Contents of the invention

[0003] The purpose of the present invention is to provide a co-rotating bevel dual gear box with a flexible shaft coupling for the distribution gear of the existing co-rotating bevel dou...
