Description
Technical field
This utility model relates to a kind of gear drive, refers specifically to a kind of anti abrasive double crosslinking gear shaft.
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.
Utility model content
This utility model purpose be propose to overcome the deficiencies in the prior art a kind of wear-resistant, service life length double crosslinking gear shaft.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of anti abrasive double crosslinking gear shaft, 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；Described little axle body is provided with annular rear oil groove with the junction of aft pillow block.
Preferably, described gear wheel key and little gear key are in the same plane.
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
Double crosslinking gear shaft of the present utility model, its axle body be two grades stepped, for installing different size of two gears, it is provided with front oil groove between its forward pillow and big axle body, it is provided with rear oil groove between its little axle body and aft pillow block, the abrasion when design of oil groove front and back can make entirety be substantially reduced work, effectively extends working life.

Below in conjunction with the accompanying drawings technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of double crosslinking gear shaft of the present utility model；
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, rear oil groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in Figure 1, the anti abrasive double crosslinking gear shaft of one described in the utility model, 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；Described little axle body 4 is provided with annular rear oil groove 8 with the junction of aft pillow block 2.
Further instruction, described gear wheel key 5 and little gear key 6 are in the same plane.
Double crosslinking gear shaft of the present utility model, its axle body be two grades stepped, for installing different size of two gears, it is provided with front oil groove between its forward pillow and big axle body, it is provided with rear oil groove between its little axle body and aft pillow block, the abrasion when design of oil groove front and back can make entirety be substantially reduced work, effectively extends working life.
Below it is only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, within the scope of all falling within this utility model rights protection.
