Abstract
A composite worm gear relates to the improvement of a worm gear structure. The utility model provides the composite worm gear which can save large amount of copper alloy materials. The composite worm gear comprises a worm gear. The key point of the structure is that the worm gear consists of a steel substrate and a copper alloy composite layer, wherein the copper alloy composite layer is arranged on the surfaces of gear teeth of steel substrate.
Description
Technical field:
The utility model relates to the improvement of worm gear arrangement.
Background technique:
Worm-and-wheel gear is commonly used to transmit motion and the power between two alternating axiss.When worm gear, worm meshing transmission, the relative sliding velocity of meshing wheel between cog is big on the one hand, so frictional loss is big, efficient is low; Relative sliding velocity is big on the other hand, makes that tooth surface abrasion is serious, heating is serious.In order to make flank of tooth heat radiation better and to reduce wearing and tearing, worm gear adopts all-in-one-piece Cu alloy material to make usually, therefore, causes the waste of a large amount of expensive Cu alloy materials.
The model utility content:
The utility model is exactly at the problems referred to above, and a kind of composite worm wheel that can save Cu alloy material in a large number is provided.
For achieving the above object, the utility model adopts following technological scheme, and the utility model comprises worm gear, and its structure outline worm gear is that the Cuprum alloy composite bed that is provided with on the surface by the steel base and the steel base gear teeth constitutes.
The beneficial effects of the utility model:
1, save a large amount of Cuprum alloys:
Constitute because the utility model is the Cuprum alloy composite bed that is provided with on the surface by the steel base and the steel base gear teeth, it is the worm gear of Cuprum alloy gear ring fully that worm gear of the present utility model replaces existing, can save a large amount of Cu alloy materials;
2, wear resistance is good, intensity is high:
Steel base of the present utility model can be made by carbon steel formula alloyed steel, is easy to satisfy requirement of strength; And the tooth surface of Cuprum alloy can be made of better material, creates more advantageous conditions for reaching better cost performance;
3, be widely used:
The utility model can be widely used in the antifriction quality of worm gear and wear resistance are required on the stricter equipment, as the worm gear on grinding machine, lathe, the various transmission device etc.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises worm gear 1, and worm gear 1 is that the Cuprum alloy composite bed 4 that is provided with on the surface by the steel base 2 and steel base 2 gear teeth 3 constitutes.
Cuprum alloy composite bed 4 of the present utility model can be compounded on the gear teeth 3 surfaces of steel base 2 by built-up welding or diffusion, again through being machined to the dimensional accuracy of requirement.
