Abstract
The utility model relates to the stable splined shaft of a kind of meshing performance, there is splined shaft body, the head of described splined shaft body is provided with outside thread, the intermediate portion of splined shaft body is set to taper type mounting end, on mounting end, be provided with keyway, mounting end is connected by grinding undercut with the rear end of splined shaft body, on the rear end of splined shaft body, is provided with gear.The utility model is simple in structure, easy to use, multiple tooth work, and meshing performance is good, and bearing capacity is good, and steering capability is high, and stress is concentrated little, processing and easily manufactured, machining accuracy is high, is difficult for affecting user's normal work, increases work efficiency, and reduces production costs.
Description
Technical field
The utility model relates to the stable splined shaft of a kind of meshing performance.
Background technique
Splined shaft is mechanical transmission one, the same with flat key, woodruff key, taper key effect, all to transmit mechanical torque, there is longitudinal keyway in the appearance of axle, the revolving part being enclosed within on axle also has corresponding keyway, can keep with axle synchronous rotary, in rotation, what have can also do longitudinal sliding motion on axle, as gearbox shifting gear etc.Splined shaft utilizes ball and coordinating of keyway to reach circumferential registration, is more suitable for precision equipment and supports the use.In use easily generation engagement is unstable for the splined shaft using now, and bearing capacity is poor, and steering capability is poor, stress is concentrated, and in the time of processing grinding, cannot obtain higher precision, affects user's normal work simultaneously, reduce working efficiency, improve cost of production.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide the meshing performance that a kind of machining accuracy is high stable splined shaft.
The utility model solves the technological scheme that its technical problem adopts: the splined shaft that a kind of meshing performance is stable, there is splined shaft body, the head of described splined shaft body is provided with outside thread, the intermediate portion of splined shaft body is set to taper type mounting end, on mounting end, be provided with keyway, mounting end is connected by grinding undercut with the rear end of splined shaft body, on the rear end of splined shaft body, is provided with gear.
Further, between described outside thread and mounting end, be provided with tool withdrawal groove.
Further, on the outer surface of described splined shaft body, be provided with quench hardened case.
Further, on described quench hardened case, be coated with wearing layer.
Further, described gear is connected by fillet with splined shaft body.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, multiple tooth work, meshing performance is good, bearing capacity is good, steering capability is high, and stress is concentrated little, processing and easily manufactured, machining accuracy is high, be difficult for affecting user's normal work, increase work efficiency, reduce production costs.
Brief description of the drawings
