Abstract
The utility model discloses a worm of a speed reducer. The worm of the speed reducer comprises a shaft body, wherein the shaft body comprises a left shaft body (1), a helical tooth segment (2), a right shaft body (3) and a gear shaft segment (4) which are orderly arranged from left to right, an inner thread hole (7) is arranged on the center of the outer end surface of the left shaft body (1), a tangent plane (5) is arranged on a position of the outer surface of the gear shaft segment (4) close to the outer end surface, and a pin hole (6) is arranged on the tangent plane (5). Because the tangent plane is arranged on the gear shaft segment, the worm of the speed reducer can be steadily provided with gear parts, is fixed through pins in the axial direction, is beneficial for driving, is simple and convenient to process and reasonable in structure design, and has practicality.
Description
Technical field
The utility model relates to a kind of transmission shaft, is specifically related to a kind of worm screw of speed reducer.
Background technique
Worm-gear speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, the winding number of motor (motor) is decelerated to desired winding number, and obtain the mechanism of larger torque.For the mechanism of transferring power and motion, the application area of speed reducer is quite extensive at present.Along with industrial expansion, more and more higher to the performance requirement of speed reducer, and worm screw is wherein important constituent element, the quality of its structure is directly determining the performance of speed reducer.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of worm screw of speed reducer, and its transmission is stable, process easy, reasonable in design.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of worm screw of speed reducer, comprise axis body, described axis body comprises left axis body (1), helical tooth section (2), right axis body (3) and the gear shaft part (4) that from left to right sets gradually, described left axis body (1) center, exterior edge face is provided with interior threaded hole (7), described gear shaft part (4) outer surface is provided with a tangent plane (5) near the place, exterior edge face, and described tangent plane (5) are provided with a pin hole (6).
Described left axis body (1) exterior edge face periphery is provided with chamfering (8).
(3) beneficial effect
The utility model is compared to prior art, and it has following beneficial effect: because the gear shaft part is provided with the tangent plane, gear part can be installed steadily, add that pin carries out axial restraint, be conducive to transmission, and its processing is easy, reasonable in design has practicability.
Description of drawings
Fig. 1 is the structural representation of the worm screw of the utility model speed reducer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The worm screw of a kind of speed reducer as shown in Figure 1, comprise axis body, axis body comprises left axis body 1, helical tooth section 2, right axis body 3 and the gear shaft part 4 that from left to right sets gradually, and center, left axis body 1 exterior edge face is provided with interior threaded hole 7, and interior threaded hole is used for and is connected axial workpiece and is fixed connection.Gear shaft part 4 outer surfaces are provided with a tangent plane 5 near the place, exterior edge face, and tangent plane 5 is provided with a pin hole 6, and left axis body 1 exterior edge face periphery is provided with chamfering 8.On the gear shaft part, the gear with same tangent plane can be installed, then fix with pin, carry out axial restraint, it is compared to the fixing gear of key, easy to process to part not only, and transmission stability is higher, and the setting of chamfering has avoided the acute angle on the axis body to occur, preventing from colliding with causes damage parts, but the working life of extending shaft.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. the worm screw of a speed reducer, comprise axis body, it is characterized in that: described axis body comprises left axis body (1), helical tooth section (2), right axis body (3) and the gear shaft part (4) that from left to right sets gradually, described left axis body (1) center, exterior edge face is provided with interior threaded hole (7), described gear shaft part (4) outer surface is provided with a tangent plane (5) near the place, exterior edge face, and described tangent plane (5) are provided with a pin hole (6).
2. the worm screw of speed reducer according to claim 1, it is characterized in that: described left axis body (1) exterior edge face periphery is provided with chamfering (8).
