Abstract
The utility model relates to a variable-pitch worm, which belongs to the field of machine tools and is provided with a worm. The variable-pitch worm is characterized in that the pitch of the worm gradually increases from left to right. In the utility model, the maintenance frequency can be reduced and the processing precision of the machine tool can be improved; in a dual-pitch worm, a worm gear pair transmits, and after the worm gear pair is abraded, worm gear pair gaps are eliminated through axially regulating a screw to reach a better meshing condition, thereby, the work efficiency of the machine tool is improved.
Description
Technical field
The present invention relates to machine tool field, especially a kind of varying pitch worm screw that is used for the gear hobbing machine worktable calibration.
Background technology
As everyone knows, worm gear exists relatively and slides when work, inevitably produce friction, make the worm gear wearing and tearing, the gap of worm gear is strengthened, and causes transmission not steady, transmission accuracy descends, do not satisfy processing request, so must the periodic maintenance worm gear even more renew worm screw, maintenance difficult, cost is too high, causes capacity utilization to descend.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of varying pitch worm screw, reduce maintenance frequency, improve machine finish, the two pitch airscrew worm screw, the worm gear transmission can be after the worm gear wearing and tearing, axially adjust worm screw and can reach meshing condition preferably, improve the operating efficiency of lathe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of varying pitch worm screw, be provided with worm screw, and it is characterized in that the pitch of worm screw increases from left to right gradually.
The invention has the beneficial effects as follows, reduce maintenance frequency, improve machine finish, the two pitch airscrew worm screw, the worm gear transmission can be eliminated the worm gear gap by axial adjustment screw rod and reach meshing condition preferably after the worm gear wearing and tearing, improves the operating efficiency of lathe.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
1. worm screws among the figure.
The specific embodiment
In Fig. 1, the present invention is provided with worm screw 1, and the pitch of worm screw 1 increases from left to right gradually.In use when worm gear is worn and torn, to adjust the pad attenuate, by square toes rotary worm 1, make worm screw 1 axially move left certain distance, because worm screw 1 pitch increases from left to right gradually, therefore make worm screw 1 and worm gear gap reach the purpose of elimination, adjust the back tightening nuts and prevent that worm screw 1 from axially collecting together by axial adjustment.In order to guarantee after the worm gear thermal deformation good lubricating condition to be arranged, guarantee precision again, so worm screw, the worm gear clearance gauge fixes in 0.08 ~ 0.12 scope.
