Gear box redirection mechanism with floating intermediate wheel

Abstract

The invention provides a gear box redirection mechanism with a floating intermediate wheel. A set of self-aligning bearings is used for replacing two sets of tapered roller bearings in the prior art,inner rings of the self-aligning bearings sleeve an intermediate shaft in a movably matched mode, and outer rings are fixed to a center hole of the intermediate wheel. A plurality of elastic elementsare installed at the left end of the intermediate shaft to push the inner rings of the self-aligning bearings. The inner rings of the self-aligning bearings push rolling bodies of the self-aligning bearings, the rolling bodies push the outer rings of the self-aligning bearings, the intermediate wheel driven by the outer rings slides axially along the intermediate shaft, tooth surface of the intermediate wheel is always close to tooth surfaces of a first bevel gear and a second bevel gear, so that the intermediate wheel has a self-aligning floating function. According to the gear box redirection mechanism with the floating intermediate wheel, the contact area of the tooth surface of a transmission gear is increased, the contact accuracy is improved, and the service life of a gear is prolonged; the mechanism is novel and simple, the manufacturing cost is low, and the installation is convenient; the overall structure of an original gear box is not changed.

Description

technical field [0001] The invention belongs to the technical field of gear box direction-changing mechanisms, and in particular relates to a gear box direction-changing mechanism with floating intermediate wheels for single-power, concentric shaft bidirectional output and direction-changing. Background technique [0002] In the gearbox reversing mechanism used in various industries, the transmission shaft generally adopts a fixed mode, such as figure 1 As shown, the power is input by the transmission shaft 9, which drives the first bevel gear 1 to rotate, and the first bevel gear 1 drives the intermediate wheel 2 to rotate through the intermediate shaft 5 and two sets of tapered roller bearings 4 located on the intermediate shaft 5, and the intermediate wheel 2 Drive the second bevel gear 3 to rotate, and the second bevel gear 3 drives the direction changing shaft 10 to rotate, thereby realizing the rotation output in the opposite direction to the concentric transmission sh...

AI Technical Summary

Problems solved by technology

However, since the first bevel gear 1, the intermediate gear 2 and the second bevel gear 3 are all fixedly connected, the contact accuracy of the gear pair is reduced due to processing and assembly errors, resulting in excessive wear of the tooth surface, and the gear box is scrapped, which affects the progress of the project , increasing the cost
