Abstract
A novel joint tooth gear comprises joint teeth and a gear, wherein the joint teeth and the gear are connected, a boss is formed on each joint tooth, and a groove matched with the boss is formed on the gear; the inner wall and the outer wall of the groove are both arranged along the radial direction of the gear, and the groove is of a straight surface structure; compared with the prior art, through improving the joint tooth structure, increase the boss setting, make and eliminate gear assembly cavity structure, it with press the complete laminating of gear, no shot gets into the gear in the course of working to this structure still increases joint tooth intensity, and the reinforcing stability of shifting makes it can bear bigger impact of shifting, reaches the purpose of safe shifting.
Description
Technical Field
The utility model relates to the technical field of gears, in particular to a novel joint gear.
Background
The joint tooth is through heating, the pressure equipment, the welding is on the gear, there is the oil spot and there is the cinder on the surface after the heat treatment carburizing and quenching, utilize the peening to get rid of surperficial oil spot and cinder after the heat treatment, and meshing NVH and gear surface residual stress will be improved during gear design, carry out powerful peening to the flank of tooth after the finish machining after the heat treatment, if structural design is unreasonable, during peening and powerful peening, the steel shot easily drops in gear cavity department, difficult clearance, detect to gear cleanliness and cause the difficulty, if the assembly is at the gearbox, the steel shot drops in the meshing district in the course of the work, there is very big hidden danger to user's safety.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provides a novel joint gear which is safe and reliable, prolongs the service life of a cutter and ensures the stability of a machining process.
In order to achieve the purpose, the utility model adopts the following technical scheme: a novel joint tooth gear comprises joint teeth and a gear, wherein the joint teeth and the gear are connected, a boss is formed on each joint tooth, and a groove matched with the boss is formed on the gear; the inner wall and the outer wall of the groove are arranged along the radial direction of the gear, and the groove is of a straight surface structure.
As a preferable scheme of the utility model, the boss is in clearance fit with the groove.
In a preferred embodiment of the present invention, the boss has a thickness of 1 mm.
As a preferable scheme of the utility model, the depth of the groove is 1-1.05 mm.
In a preferred embodiment of the present invention, the diameter of the groove is 75 mm.
As a preferable scheme of the present invention, an overtravel groove is provided between the boss and the groove.
In a preferred embodiment of the present invention, the boss and the engaging tooth are integrally formed.
Compared with the prior art, the utility model has the beneficial effects that: through improving joint tooth structure, increase the boss setting, make and eliminate gear assembly cavity structure, it with press the complete laminating of pressing the gear, no shot gets into the gear in the course of working to this structure still increases joint tooth intensity, strengthens the stability of shifting, makes it can bear bigger shift impact, reaches the purpose of safe shifting.

Detailed Description
The following describes embodiments of the present invention in detail with reference to the accompanying drawings.
As shown in fig. 1-3, a novel joint tooth gear comprises a joint tooth 2 and a gear 1 which are connected, wherein a boss 2-1 is formed on the joint tooth 2, and a groove 1-1 matched with the boss 2-1 is formed on the gear 1; the inner wall and the outer wall of the groove 1-1 are arranged along the radial direction of the gear 1, and the groove 1-1 is of a straight surface structure.
The boss 2-1 is in clearance fit with the groove 1-1, and steel shots in the machining process cannot fall into the gear assembly, so that the cleanliness of the gear is improved, and hidden dangers of users are eliminated.
The thickness of the boss 2-1 is 1mm, the depth of the groove 1-1 is 1-1.05mm, and the depth of the groove 1-1 is not less than the thickness of the boss 2-1, so that the boss 2-1 is completely embedded in the groove 1-1.
The diameter of the groove 1-1 is 75mm, and compared with the prior art, the diameter width of the groove 1-1 is reduced, so that the radial wall thickness of the gear is increased, and the overall strength of the gear is improved.
An overtravel groove is arranged between the boss 2-1 and the groove 1-1, so that interference between the gear 1 and the joint teeth 2 during press fit is avoided.
The boss 2-1 and the engaging teeth 2 are of an integrally formed structure, so that the boss 2-1 and the engaging teeth 2 have better strength.
When the joint teeth 2 are produced, a boss 2-1 is additionally arranged to be matched with the press-fit gear 1; when the gear 1 is machined, the depth of a groove 1-1 is adjusted from 1.8mm (+0.2/0) to 1mm (+0.05/0) by changing the angle of a cutter and the feed mode, the diameter of the groove is changed from phi 76mm to phi 75mm (+0.05/0), compared with the prior machining, the cutting time and the cutting allowance are reduced, the service life of the cutter is prolonged, and the stability of the machining process is ensured by controlling the CPK in the machining process; 2-1 length of each batch of sampling inspection bosses and 1-1 depth and diameter of the gear groove ensure the stability of the processing process; during press fitting, the press fitting machine is correctly operated, and quality risks caused by improper press fitting are eliminated.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model; thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
Although the reference numerals in the figures are used more here: gear 1, groove 1-1, engagement tooth 2, boss 2-1, etc., but does not exclude the possibility of using other terms. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
