Abstract

The invention relates to a turning gear device for shaft machining. The turning gear device comprises a worm wheel bracket and is characterized in that a first worm wheel-worm assembly and a second worm wheel-worm assembly are mounted on the worm wheel bracket; the first worm wheel-worm assembly comprises a first worm wheel and a first worm which are engaged with each other; the second worm wheel-worm assembly comprises a second worm wheel and a second worm which are engaged with each other; each of two ends of the first worm is mounted in the worm wheel bracket through a first tapered roller bearing; the other end of the first worm is fixedly arranged in an inner hole of the second worm wheel through a second flat key; each of two ends of the second worm is mounted in the worm wheel bracket through a second tapered roller bearing; and one end of the second worm is provided with a hand wheel through the first flat key. With the adoption of the turning gear device for the shaft machining, shaft parts are rotates for many times when machined, so that the turning gear device has the advantages of low manufacturing cost, operation simpleness and high security.

Description

technical field [0001] The invention relates to a barring device for shaft machining, in particular to a barring device for shaft parts that are heavy and require multiple rotations during machining. Background technique [0002] For the heavy shaft parts, the rotation of the heavy shaft parts cannot be realized by using ordinary tooling. If it is hoisted and rotated by a crane, there are serious safety hazards, and the rotation angle is not easy to control, and the accuracy is inaccurate. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a turning device for shaft machining, which realizes multiple rotations during machining of shaft parts, has low manufacturing cost, simple operation and high safety. [0004] According to the technical solution provided by the present invention, the cranking device for shaft machining includes a worm gear bracket, and is characterized in that: a first w...
