Abstract
The utility model discloses a novel half shaft gear, and particularly relates to the technical field of machinery. The utility model solves the problem that the safety of an automobile is affected by easy tooth collapse in the existing half-shaft gear reuse process.
Description
Technical Field
The utility model belongs to the technical field of machinery, and particularly relates to a novel half-shaft gear.
Background
The half shaft gear is a bevel gear, is an important component for forming an automobile differential mechanism, and has a structure that bevel gears face outwards and a spline shaft hole is arranged in the middle. The built-in gear of the automobile differential mechanism needs a good lubrication environment, and in order to prevent the lubricating oil in the differential mechanism from overflowing, each output end is provided with a corresponding sealing structure. In the use process of the half shaft gear in the current market, the phenomenon that teeth are easy to crack exists, the service life can be influenced, the safety performance of an automobile can also be influenced, and the shaft hole and the rotating shaft of the half shaft gear are easy to wear, so that the transmission stability is influenced.
Disclosure of Invention
The utility model provides a novel half-shaft gear, which solves the problem that the safety of an automobile is affected by easy tooth collapse in the existing half-shaft gear reuse process.
The technical aim of the utility model is realized by the following technical scheme: the utility model provides a novel semi-axis gear, includes the shaft, be equipped with the wheel body on the shaft, be equipped with a plurality of outer teeth of a cogwheel on the outer wall of wheel body, adjacent two form the tooth's socket between the outer teeth of a cogwheel, the junction of wheel body and wheel body is opened there is the round arc wall, be equipped with between arc wall and the teeth of a cogwheel and strengthen the root.
Principle and effect of the technology: support the teeth of a cogwheel through strengthening the root to make the teeth of a cogwheel can bear bigger force when atress operation, thereby increase the life of semi-axis gear.
Further, the arc groove has a notch radian of 90 degrees.
By adopting the scheme, the stress concentration phenomenon is reduced by the arc-shaped grooves, and the overall strength and the extrusion resistance of the half shaft gear are improved.
Further, the wheel shaft and the wheel body are provided with inner spline shaft holes which are coaxially arranged.
By adopting the scheme, the side gear is convenient to be connected with other parts of the differential mechanism.
Further, a spiral oil through groove is formed in the inner spline shaft hole, two oil through holes are formed in the wheel shaft in the radial direction, and the two oil through holes are respectively communicated with notch openings at two ends of the oil through groove.
By adopting the scheme, the oil through groove is used for lubricating oil to enter, so that the internal spline is lubricated.
Further, an oil outlet is formed in the reinforcing root.
By adopting the scheme, the oil outlet can lead the lubricating oil to lubricate the external gear teeth, thereby reducing the abrasion of the external gear teeth and prolonging the service life of the external gear teeth.
Compared with the prior art, the utility model has the beneficial effects that: the integral strength of the half shaft gear is improved through the reinforcing root, the extrusion resistance is good, the service life of the outer gear teeth is long, the abrasion is small, the working is more stable, and the noise is small.
Drawings
FIG. 1 is a schematic view of a novel side gear of the present utility model;
in the figure: 1. a wheel axle; 2. a wheel body; 3. external gear teeth; 4. an internal spline shaft hole; 5. oil through grooves; 6. oil holes; 7. an arc-shaped groove; 8. strengthen the root.
Detailed Description
The following is a detailed description of the embodiments.
Examples: as shown in figure 1, the novel half-shaft gear comprises a wheel shaft 1, wherein the left side of the wheel shaft 1 is provided with a wheel body 2 which is connected into a whole, and the outer wall of the wheel body 2 is provided with a plurality of outer gear teeth 3 which are arranged at intervals. Tooth grooves are formed between two adjacent outer gear teeth 3. The joint of the wheel body 2 and the wheel shaft 1 is provided with a plurality of arc grooves 7 which are arranged at intervals, the number of the arc grooves 7 is consistent with that of tooth grooves, and the radian of the groove grooves 7 is 90 degrees. A reinforcing root 8 is arranged between the arc-shaped groove 7 and the tooth groove, the inner opening of the reinforcing root 8 is provided with an oil outlet, and lubricating oil can be conveyed onto the outer gear teeth 3 through the oil outlet. The wheel axle 1 and the wheel body 2 are provided with an inner spline shaft hole 4 which is coaxially arranged, the side wall of the inner spline shaft hole 4 is provided with a spiral oil through groove 5, the upper side and the lower side of the wheel axle 1 are respectively provided with two oil through holes 6, and the two oil through holes 6 are respectively communicated with two notches of the oil through groove 5.
When the side gear works, the reinforcing root 8 can play a supporting role on the outer gear teeth 3, so that the overall strength of the side gear is improved, lubricating oil can be conveyed to the outer gear teeth 3, abrasion of the outer gear teeth 3 is reduced, and the service life of the outer gear teeth 3 is prolonged. The helical oil passage grooves 5 ensure an effective lubrication length, and at high-speed rotation, the oil passage grooves 5 facilitate circulation of lubricating oil along with rotation of the wheel shaft 1, thereby ensuring a lubrication effect.
The foregoing description of the embodiments of the present utility model will not be repeated for all common sense of specific construction and characteristics known in the art, and it should be noted that, for those skilled in the art, modifications and improvements can be made without departing from the construction of the present utility model, and these should also be regarded as the protection scope of the present utility model, which does not affect the effect of the implementation of the present utility model and the practical applicability of the patent. The protection scope of the present utility model is subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
