Abstract
The invention discloses a duplicate gear shaft provided with a front oil groove. The duplicate gear shaft provided with the front oil groove comprises a shaft body, a front shaft stage arranged at the front end of the shaft body and a rear shaft stage arranged at the rear end of the shaft body. The shaft body is in a two-stepped shape and comprises a big shaft body and a small shaft body. The outer diameter of the big shaft body is greater than that of the small shaft body. A protruding big gear key is arranged on the outer circumference of the big shaft body. A protruding small gear key is arranged on the outer circumference of the small shaft body. The annular front oil groove is formed in the connecting position of the big shaft body and the front shaft stage. According to the duplicate gear shaft provided by the invention, the shaft body is in the two-stepped shape and used for mounting two gears with different sizes; the front oil groove is formed between the front shaft stage and the big shaft body; the design of the front oil groove can greatly reduce working abrasion of the whole duplicate gear shaft, and the service life of the duplicate gear shaft is effectively prolonged.
Description
Technical field
The present invention relates to a kind of gear drive, refer specifically to a kind of double crosslinking gear shaft with front oil groove.
Background technology
The application that gear is passed on Gong in present lathe and instrument is extremely wide, and its function is the speed ratio transmitting movement by regulation and power.At present, duplicate gear is applied in machine driving and extensively, duplicate gear is to be linked into an integrated entity on rotary gear shaft by two gear fixed covers, can not relatively rotate each other, be changed the rotating speed of output by different gear ratios.Axial workpiece by the long-term operation under fatigue stress such as frictional force, impulsive force and shearing force, easily weares and teares in motor process.How to improve the service life of axial workpiece, and processing and manufacturing cost of demoting, it has also become those skilled in the art need to be solved the technical problem that.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of wear-resistant, service life length double crosslinking gear shaft.
The technical solution of the present invention is achieved in that a kind of double crosslinking gear shaft with front oil groove, the forward pillow including axle body, being arranged on axle body front end and the aft pillow block being arranged on axle body rear end；Described axle body be two grades stepped, be divided into big axle body and little axle body；The external diameter of described big axle body is more than the external diameter of little axle body；A gear wheel key protruded it is provided with on the excircle of described big axle body；A little gear key protruded it is provided with on the excircle of described little axle body；Described big axle body is provided with annular front oil groove with the junction of forward pillow.
Preferably, the left end of described big axle body is provided with and dodges chamfering.
Preferably, described gear wheel key and little gear key are in the same plane.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The double crosslinking gear shaft of the present invention, its axle body be two grades stepped, be used for installing different size of two gears, between its forward pillow and big axle body, be provided with front oil groove, the abrasion when design of front oil groove can make entirety be substantially reduced work, effectively extend working life.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the schematic diagram of the double crosslinking gear shaft of the present invention；
In figure: 1, forward pillow；2, aft pillow block；3, big axle body；4, little axle body；5, gear wheel key；6, little gear key；7, front oil groove；8, chamfering is dodged.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of double crosslinking gear shaft with front oil groove of the present invention, the forward pillow 1 including axle body, being arranged on axle body front end and the aft pillow block 2 being arranged on axle body rear end；Described axle body be two grades stepped, be divided into big axle body 3 and little axle body 4；The external diameter of described big axle body 3 is more than the external diameter of little axle body 4；A gear wheel key 5 protruded it is provided with on the excircle of described big axle body 3；A little gear key 6 protruded it is provided with on the excircle of described little axle body 4；Described big axle body 3 is provided with annular front oil groove 7 with the junction of forward pillow 1.
Further instruction, the left end of described big axle body 3 is provided with dodges chamfering 8；Described gear wheel key 5 and little gear key 6 are in the same plane.
The double crosslinking gear shaft of the present invention, its axle body be two grades stepped, be used for installing different size of two gears, between its forward pillow and big axle body, be provided with front oil groove, the abrasion when design of front oil groove can make entirety be substantially reduced work, effectively extend working life.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
Claims (3)
