Abstract

The utility model discloses an initiative spiral bevel gear, including integrated into one piece's teeth of a cogwheel portion (1), wheel axial region (2) and screw section (3), wheel axial region (2) and screw section (3) are connected at the big footpath of teeth of a cogwheel portions (1) end in order, and the diameter of this round of axial region (2) and screw section (3) reduces in proper order the path end of teeth of a cogwheel portion (1) is equipped with along axial outside convex bearing construction section (4). Beneficial effect, installation, dismantlement convenience have reduced work load, have reduced the mechanical loss to the bearing, have improved mechanical efficiency and stability.

Description

Spiral bevel driving gear
Technical field
This utility model relates to gear technique field, specifically, is a kind of spiral bevel driving 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.
In existing machine driving, gear many employings ferrous materials is made, and causes that gear is comparatively heavy, in installation and removal process, it is often necessary to multi agent cooperation, could be dismounted by gear; When carrying out gear installation, it is impossible to firmly install, when dismantling, it is impossible to gear is taken out smoothly, and there is potential safety hazard.
Utility model content
In order to solve the problems referred to above, the utility model proposes a kind of spiral bevel driving gear, by existing gear is improved, make gear installing/dismounting convenient, reduce workload, make gear be more firmly mounted.
For reaching above-mentioned purpose, the concrete technical scheme that this utility model adopts is as follows:
A kind of spiral bevel driving gear, teeth portion, wheel shaft portion and threaded shank is taken turns including integrated, described wheel shaft portion and threaded shank are sequentially connected with the bigger diameter end in wheel teeth portion, the diameter of this wheel shaft portion and threaded shank is sequentially reduced, and is provided with the bearing construction section protruded axially outward at the described miner diameter end taking turns teeth portion.
Further describing, described teeth portion of taking turns is spiral bevel gear, and this anglec of rotation taking turns teeth portion is left-handed 45 degree to 50 degree.
Further describe, more firm in order to make gear be mounted so as to, the periphery wall of described threaded shank is additionally provided with at least 6 locking pin-and-holes so that staff can low-angle ground swing pinion, what make that gear installs is more firm.
Further describe, in order to make to be easily installed, be provided with the shaft shoulder for coordinating with bearing inner race described wheel between teeth portion with described bearing construction section.
Further describe, in order to make readily accessible gear, it is laid with at least two kerve near the end of described bearing construction section at the described shaft shoulder, one notch of described kerve is arranged on the periphery wall of the described shaft shoulder, and another notch of described kerve is arranged on the periphery wall of described bearing construction section.
This utility model beneficial effect: by arranging multiple locking pin-and-hole on gear, staff can low-angle ground swing pinion, gear is made to be more firmly mounted and convenient, gear arranges kerve, when gear disassembling, by kerve, bearing can be dismantled, it is to avoid damage to bearing.
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. threaded shank, 4. bearing construction section, 5. locking pin-and-hole, the 6. shaft shoulder, 7. kerve.
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 can be seen from Figure 1, a kind of spiral bevel driving gear, teeth portion 1, wheel shaft portion 2 and threaded shank 3 is taken turns including integrated, wheel shaft portion 2 and threaded shank 3 are sequentially connected with the bigger diameter end in wheel teeth portion 1, the diameter of this wheel shaft portion 2 and threaded shank 3 is sequentially reduced, and the miner diameter end in wheel teeth portion 1 is provided with the bearing construction section 4 protruded axially outward;
It is seen also in fig. l that wheel teeth portion 1 is spiral bevel gear; The periphery wall of threaded shank 3 is additionally provided with 6 locking pin-and-holes 5; It is provided with the shaft shoulder 6 for coordinating with bearing inner race between wheel teeth portion 1 and bearing construction section 4; Being laid with at least two kerve 7 at the shaft shoulder 6 near the end of bearing construction section 4, a notch of kerve 7 is arranged on the periphery wall of the shaft shoulder 6, and another notch of kerve 7 is arranged on the periphery wall of bearing construction section 4.
In the present embodiment, the anglec of rotation taking turns teeth portion 1 is left-handed 50 degree.
