Abstract
The invention relates to a double-channel pressure-injection type lubricating nozzle. The double-channel pressure-injection type lubricating nozzle comprises a bulb and a connecting pipe which is integrally formed with the bulb, wherein lubricating oil channels are arranged in the bulb and the connecting pipe; a connecting thread is formed on the outer wall of the connecting pipe; a first threaded hole and a second threaded hole are formed in the bulb; the nozzle further comprises a first oil injection nozzle and a second oil injection nozzle. By arranging two symmetrical threaded holes in the bulb, the oil injection nozzles connected to the two threads are used for conveniently injecting lubricating grease, so that the lubricating grease can be injected without adjusting the position of a moving part or the directions of the oil injection nozzles. As the two oil injection nozzles are symmetrically arranged on the bulb, when the bulb is mounted on a rotary part, dynamic unbalance of the rotary part is reduced.
Description
Technical field
The invention belongs to lubrication technical field, referring to especially a kind ofly provides the bilateral press injecting type grease fitting of lubrication for relative movement part.
Background technique
The parts with relative movement generally all need lubricating grease (oil) to lubricate, and the parts grease ups (oil) such as existing cross axle, sliding bearing, pin are all annotated by oil nozzle.Existing press injecting type oil nozzle is single-pass configuration, when some grease up, due to the position influence that insufficient space or revolving part stop, needing the direction adjusting movement parts position or adjustment pump nozzle, thus makes troubles to filling.
As shown in Figure 1, existing grease fitting structure includes sealing ball 1, pump nozzle 2, pump nozzle connecting thread 3, bulb 4, hexagon head 5, bulb connecting thread 6 and spring 7; Pump nozzle 2 is fixed on bulb 4 by pump nozzle connecting thread 3, is fixed on the parts tapped hole needing lubrication by bulb connecting thread 6.The structure of pump nozzle 2 is, inside is hollow passageway, spring 7 is provided with in passage, spring 7 compresses end sealing ball 1 being withstood on the hollow passageway of pump nozzle 2, when needs are grease-added, by grease gun top on sealing ball 1, spring 7 is compressed, by lubricating grease (oil) pressure injection in the hollow passageway of pump nozzle, then by the position of hollow passageway pressure injection to needs lubrication.
The main deficiency of existing technology is:
1) existing grease fitting is single channel, pump nozzle can only towards a direction, and when pump nozzle is arranged on revolving part, the position stopped due to revolving part is uncertain, cause the direction needing when charging-up lubricant oil to adjust revolving part position or need with spanner adjustment pump nozzle, filling inconvenience;
2), after pump nozzle rotates with spanner, there is the risk of bulb threaded connection place leakage of oil;
3) in industrial and mineral rugged environment, if pump nozzle occurs blocking or damages, lubricating grease can be caused to annotate when lacking accessory;
4) this structure is non-symmetry structure, and gyration center does not overlap with barycenter, is arranged on rotary component and causes dynamic unbalance.
Summary of the invention
The object of the invention is to propose improvement opportunity scheme to existing grease fitting, by the technical program, make grease adding convenient, the direction that can adjust movement parts position or pump nozzle just can complete the filling of lubricating grease; Meanwhile, do not need loosening bulb connecting thread to regulate pump nozzle direction, avoid the leakage of lubricating grease;
And blocking or the damage problem of pump nozzle can be solved, and reduce the imbalance problem of revolving part.
The present invention is achieved by the following technical solutions:
A kind of bilateral press injecting type grease fitting, the connecting tube including bulb and be structure as a whole with described bulb; Grease channel is provided with in described bulb and described connecting tube; The outer wall of described connecting tube is provided with connecting thread;
