Abstract
The utility model discloses a differential headstock, comprising a box body, a worm wheel and a worm, wherein the worm wheel shaft is arranged in the horizontal direction; the worm shaft is arranged in the vertical direction; one end of the worm is arranged on the top part of the box body by a roller bearing; the middle part of the box body is provided with a supporting platform; the supporting platform is provided with a bearing seat; the other end of the worm is arranged in the bearing seat by the roller bearing; and a planar rolling device is also arranged between the worm and the bearing seat. The differential headstock has the advantages of effectively solving the friction between steps of the worm and the bearing seat and improving the running stability of the differential headstock.
Description
Technical field
The utility model relates to a kind of gear-box, specifically, relates to differential headstock.
Background technique
Differential headstock is mounted in the rearmounted cradle of stranding machinery, realizes back twist and no back twist under differential action, is the key equipment of producing fan-shaped line.Existing differential headstock is to adopt turbine and worm to cooperate power is imported differential headstock, cooperating speed governing output by internal gear, worm screw is provided with, the end of worm screw is installed in the gear housing top by rolling bearing, the rolling bearing that the lower end of worm screw is passed in bearing support and the bearing support cooperates, but the step of worm screw directly contacts with bearing support like this, uses an end can make worm screw step or bearing support produce wearing and tearing after the time, causes differential headstock fluctuation of service.
The model utility content
The purpose of this utility model is to provide differential headstock, can effectively solve between the worm screw of existing differential headstock and the bearing support problem by the frictional influence overall operation.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: differential headstock, comprise casing, turbine, worm screw, described turbine shaft is horizontally disposed with, and described worm shaft vertically is provided with, and described worm screw one end is arranged on the casing top by rolling bearing, described casing middle part is provided with support platform, described support platform is provided with bearing support, and the other end of described worm screw is arranged in the bearing support by rolling bearing, also is provided with the plane rolling device between described worm screw and the bearing support.
Preferably, described plane rolling device is a plane bearing; Simple and practical reliable performance.
Compared with prior art, the utility model has the advantages that: can effectively solve step of worm screw and the friction between the bearing support, improve the operation stability of differential headstock.
