The purpose of this utility model is for the defective of prior art and deficiency, and rotation keyway worm gear a kind of simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of rotation keyway worm gear described in the utility model, comprise worm wheel body, described worm wheel body is comprised of arc worm gear and stationary axle body, described arc worm gear is arranged on the outer circle wall of stationary axle body, described arc worm gear is provided with several gears, described gear is circularly and evenly distributed on the outer circumferential edge of arc worm gear, the central position of described stationary axle body is provided with axle sleeve hole, evenly be provided with several stationary axle gears on the inner peripheral wall of described axle sleeve hole, described stationary axle wheel tooth is connected to running shaft, be provided with the running shaft gear that matches with the stationary axle gear on the cylindrical wall of described running shaft, the central position of described running shaft is provided with rotary shaft hole, is provided with keyway on the round wall of described rotary shaft hole.
Further, the side of described stationary axle body is provided with several fixed holes.
Further, described fixed hole is two, and fixed hole is on the side that is symmetricly set on fixed axle sleeve.
Further, described fixed hole is screw fixed hole or pin fixed hole.
After adopting said structure, the utility model beneficial effect is: a kind of rotation keyway worm gear described in the utility model, comprise worm wheel body, described worm wheel body is comprised of arc worm gear and stationary axle body, described arc worm gear is arranged on the outer circle wall of stationary axle body, described arc worm gear is provided with several gears, described gear is circularly and evenly distributed on the outer circumferential edge of arc worm gear, the central position of described stationary axle body is provided with axle sleeve hole, evenly be provided with several stationary axle gears on the inner peripheral wall of described axle sleeve hole, described stationary axle wheel tooth is connected to running shaft, be provided with the running shaft gear that matches with the stationary axle gear on the cylindrical wall of described running shaft, the central position of described running shaft is provided with rotary shaft hole, be provided with keyway on the round wall of described rotary shaft hole, when using the utility model, the angle of regulating keyway by the position of regulating running shaft, greatly improved the flexibility of worm gear and supporting axle (or valve body) assembling, and easy to install, can further promote worm geared application.The utlity model has simple in structurely, arrange rationally, the advantage such as fabricating cost is low.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Figure 1-3, a kind of rotation keyway worm gear described in the utility model comprises worm wheel body A, and described worm wheel body A is comprised of arc worm gear 1 and stationary axle body 2; Described arc worm gear 1 is arranged on the outer circle wall of stationary axle body 2, and described arc worm gear 1 is provided with several gears 11, and described gear 11 is circularly and evenly distributed on the outer circumferential edge of arc worm gear 1.The central position of described stationary axle body 2 is provided with axle sleeve hole 22, evenly be provided with several stationary axle gears 23 on the inner peripheral wall of described axle sleeve hole 22, described stationary axle gear 23 toe joints have running shaft 3, are provided with the running shaft gear 33 that matches with stationary axle gear 23 on the cylindrical wall of described running shaft 3; Running shaft 3 just can rotate running shaft 3 according to the engagement degree of stationary axle gear 23 and running shaft gear 33 like this.
The central position of described running shaft 3 is provided with rotary shaft hole 31, is provided with keyway 32 on the round wall of described rotary shaft hole 31.Like this, the user just can regulate the angle of keyway 32 by rotation running shaft 3, is mounted with sleeve body 2 in order to satisfy the client from different angles, thereby solves the assembly problem of worm gear and supporting axle (or valve body).Certainly, the number of teeth of stationary axle gear 23 and running shaft gear 33 is directly connected to the validity of the angular adjustment of keyway 32, so the number of teeth of stationary axle gear 23 and running shaft gear 33 is decided by client's real needs.
