Abstract
The utility model discloses a the initiative taper gear, including teeth of a cogwheel portion (1) the big footpath of teeth of a cogwheel portion (1) is held and is connected with a round axial region (2), spline portion (3) and screw section (4) in order the path end of teeth of a cogwheel portion (1) is connected with bearing construction section (5), the spline of spline portion (3) is involute spline. Beneficial effect, gear axle portion intensity is big, the difficult emergence is warp, has improved the life of gear, the gear can be on screw section's locking pin to carry out low -angle ground through the round pin rotatory, make the gear installation firm, the transmission process stably.
Description
Technical field
This utility model relates to a kind of gear technique field, specifically, is a kind of drive bevel gear。
Background technology
The version of gear is varied, of a great variety, as a kind of common power transmission mode, is widely used in the every field in production, life。
Owing to gear many employings ferrous materials is made, cause that gear is comparatively heavy, when the screw rod of gear rotates to a certain degree, just it is difficult to rotate, makes gear install insecure, in existing mechanical transmission course, the situations such as gear loose easily occur, owing to torsion is excessive, cause wheel shaft portion to deform, affect equipment properly functioning。
Utility model content
In order to solve the problems referred to above, the utility model proposes a kind of drive bevel gear, gear body arranges spline part, and locking pin-and-hole is set in threaded shank, and make gear firmly install, bearing intensity is high, it is not susceptible to deformation, improves the work efficiency of gear, extend the service life of gear。
For reaching above-mentioned purpose, the concrete technical scheme that this utility model adopts is as follows:
A kind of drive bevel gear, including wheel teeth portion, has been sequentially connected with wheel shaft portion, spline part and threaded shank at the described bigger diameter end taking turns teeth portion, has been connected to bearing construction section at the described miner diameter end taking turns teeth portion, and the spline of described spline part is involute spline。
Further describe, in order to make gear in installation process, it is possible to screwed by gear, described threaded shank outer wall is circumferentially evenly arranged with at least 6 locking pin-and-holes low-angle, and described locking pin-and-hole is each perpendicular to the axial line of described threaded shank, and communicate between two。
Further describe, be provided with the shaft shoulder for coordinating with bearing inner race described wheel between teeth portion with described bearing construction section。
Further describing, described teeth portion of taking turns is spiral bevel gear。
Further describing, the described spline part number of teeth is 18 teeth to 20 teeth。
The beneficial effects of the utility model: when gear is installed by threaded shank, it is possible to firmly install, bearing intensity is big, and wheel shaft portion is unlikely to deform, and improves mechanical efficiency, extends the service life of gear。
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated。
Fig. 1 is structural representation of the present utility model；
In figure, 1. take turns teeth portion, 2. wheel shaft portion, 3. spline part, 4. threaded shank, 5. bearing construction section, 6. locking pin-and-hole。
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model and operation principle are described in further detail。
As shown in Figure 1: a kind of drive bevel gear, including wheel teeth portion 1, the bigger diameter end in wheel teeth portion 1 has been sequentially connected with wheel shaft portion 2, spline part 3 and threaded shank 4, and the miner diameter end in wheel teeth portion 1 is connected to bearing construction section 5, and the spline of spline part 3 is involute spline；
It is seen also in fig. l that be circumferentially evenly arranged with at least 6 locking pin-and-holes 6 on threaded shank 4 outer wall, and the axial line in the locking equal vertical screw portion 4 of pin-and-hole 6, and communicate between two；It is provided with the shaft shoulder for coordinating with bearing inner race between wheel teeth portion 1 and bearing construction section 5。
In the present embodiment, wheel teeth portion 1 is spiral bevel gear。
In the present embodiment, spline part 3 number of teeth is 18 teeth。
