Abstract

The utility model discloses a kind of herringbone bear with annular shoe cream room, including a left part and a right part, described left part and described right part be mirror image each other, and described left part and the binding face of right part offer a cannelure, and two described cannelures are combined into an annular shoe cream room.Advantage with the herringbone bear of annular shoe cream room of the present utility model is: have left part and the split-type structural of right part composition, the processing cost of herringbone bear can be substantially reduced, the most internal have shoe cream room, the gap between left part and right part can be utilized to provide lubricating oil to wheel tooth position slowly, reach the effect of self-lubricating.

Description

Herringbone bear with annular shoe cream room

Technical field

This utility model relates to a kind of herringbone bear, a kind of herringbone bear with annular shoe cream room.

Background technology

It is little that herringbone bear not only has helical gear smooth running, noise, it is adaptable to the advantages such as high-speed overload transmission, also simultaneously Overcome the shortcoming that helical gear can produce bigger axial force；But herringbone bear also has, and processing difficulties, cost are more high to be lacked Point.Chinese invention patent application CN201410356874.0 discloses a kind of Self-lubricating gear, including gear mass, described gear mass Inside being provided with at least one shoe cream room, shoe cream room and at least two oil circuits to communicate, the oil-out of two oil circuits lays respectively at teeth groove groove The end, described gear mass is provided with the oiling screw communicated with shoe cream room, and oiling screw is threaded screw.But this gear The structure of gear can be destroyed, necessarily cause and stress concentration phenomenon occurs around shoe cream room, affect intensity and the life-span of gear.

Utility model content

This utility model mainly solves the technical problem existing for prior art, thus provides one to have left part and the right side The split-type structural of portion's composition, it is possible to be substantially reduced the processing cost of herringbone bear, the most internal have shoe cream room, it is possible to utilizes Gap between left part and right part slowly to wheel tooth position provide lubricating oil, reach self-lubricating effect with annular oil storage The herringbone bear in chamber.

This utility model solves the technical problem in the presence of prior art by following technical proposals:

A kind of herringbone bear with annular shoe cream room, including a left part and a right part, described left part and the described right side Portion is mirror image each other, and described left part and the binding face of right part offer a cannelure, and two described cannelures are combined into One annular shoe cream room, is filled with lubricating oil in described annular shoe cream room.

As this utility model preferred embodiment, the described herringbone bear with annular chamber also includes pad, described Pad be arranged between described left part and described right part.

Advantage with the herringbone bear of annular shoe cream room of the present utility model is: have left part and the split of right part composition Formula structure, it is possible to be substantially reduced the processing cost of herringbone bear, the most internal have shoe cream room, it is possible to utilize left part and right part it Between gap slowly to wheel tooth position provide lubricating oil, reach the effect of self-lubricating.

Detailed description of the invention

Below preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature energy It is easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.

Embodiment one:

As shown in Figure 1 and Figure 2, a kind of herringbone bear with annular shoe cream room, including left part 1 and a right part 2, this left side Portion 1 and this right part 2 are mirror image each other, as it is shown on figure 3, offer a cannelure 11 on the binding face of this left part 1, this right part 2 Also having a cannelure 11 (not shown in figures) on binding face, these two cannelures 11 are combined into an annular shoe cream room, this ring Shape shoe cream room is filled with lubricating oil.When this is with the herringbone bear rotation of annular shoe cream room, the lubrication in annular shoe cream room Oil can flow to the surrounding of annular shoe cream room under the influence of centrifugal force.The direction of the axial force suffered by left part 1 and right part 2 On the contrary, along with this is with the rotation of the herringbone bear of annular shoe cream room, the gap between this left part 1 and this right part 2 can be periodically Change big and diminish, the lubricating oil in annular shoe cream room can be pumped out slowly to tooth surface, reaches the effect of self-lubricating.

Embodiment two:

On the basis of embodiment one, should also include pad 3 with the herringbone bear of annular chamber, this pad 3 is arranged in this Between left part 1 and this right part 2.In embodiment one, this left part 1 and this right part 2 are directly connected to, and its seam only one of which is fuel-displaced Speed relatively slow, by adding this pad 3, a seam can be increased, improve Extraction rate, in order to reach higher fuel-displaced speed Degree can also add multiple pad 3.But the quantity of pad is too much, from this left part 1 or this right part 2 pad seam farther out it Between the lubricating oil that pumped out cannot arrive at the surface of the gear teeth smoothly, not have corresponding lubrication, therefore recommend this pad 3 Quantity is less than five.

It is only more than the mentality of designing of some embodiments of the present utility model, in the case of system allows, this reality The most external more functional module can be expanded to novel, thus extend its function to greatest extent.

The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
