Abstract
The utility model discloses a grease-circulation type methyl cellulose (MC) nylon pulley, and in particular relates to a structure of the grease-circulation type MC nylon pulley. The grease-circulation type MC nylon pulley comprises an MC nylon pulley body, a bearing, dustproof covers and an oil injection port, wherein the bearing is arranged in an inner hole of the MC nylon pulley body; the dustproof covers are arranged at the bearing ends on the two sides of the pulley; and the oil injection port is formed in the MC nylon pulley body. The grease-circulation type MC nylon pulley is characterized in that grease lateral leakage preventing devices communicated with the inner hole of the MC nylon pulley body are respectively arranged at the bearing ends on the two sides of the pulley; bulged annular rings are arranged on the dustproof covers; the dustproof covers are embedded and fixed on the bearing ends on the two sides of the pulley by the bulged annular rings to form the grease lateral leakage preventing devices; an oil discharge hole and an oil hole plug are arranged on the dustproof cover to form a waste oil discharge device, and the waste oil discharge devices and the oil injection port form a grease-circulation type injection-discharge system. The grease-circulation type MC nylon pulley has the advantages of simple structure and easiness for production, and large abrasion and high noise of the bearing caused by impurities or dirty oil are avoided, the seat comfortable sensation of human is guaranteed, and the error rate and the replacement rate of a whole operation mechanism are reduced.
Description
Technical field
The utility model relates to a kind of Wheel structure, is specifically related to the structure of the circulating MC nylon pulley of a kind of grease.
Background technique
The bearing that the MC nylon pulley that adopts in elevator industry, oilfield machinery field, pulley train center move in a circle is general to be adopted with a side dust cover (semiclosed) or both sides all with dust cover (totally-enclosed) as transmission device.When elevator moved, the chip impurity that these bearing internal motion wearing and tearing produce can't be discharged, even the noise that intermittent oiling can not be avoided the damage of bearing and cause thus.Extremely the monolithic wheel of bringing of bearing is to produce fault, and the abnormal noise effect ride comfort sense that produces of bearing, and the bearing replacing difficulty is large, has reduced the working life of bearing, and the elevator user cost improves.
The model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and can protect bearing and motion, extends its working life, reduces the circulating MC nylon pulley of grease of noise and rate of fault.
the purpose of this utility model is achieved through the following technical solutions: the circulating MC nylon pulley of grease, comprise MC nylon pulley body, be placed in the bearing of MC nylon pulley body endoporus, the dust cover of pulley both sides bearing end and be arranged on pouring orifice on MC nylon pulley body, it is characterized in that, the bearing end of described pulley both sides is respectively equipped with the grease-proof side leakage device that communicates with MC nylon pulley body endoporus, the raised annular circle is set on described dust cover, dust cover is bumped into the bearing end formation grease-proof side leakage device that is fixed on the pulley both sides by the raised annular circle, described dust cover is provided with oil drainage hole and oil-hole plug consists of Waste oil discharger.
Also be provided with the circlip of at least one rigid bearing in described MC nylon pulley body endoporus, circlip is arranged on described bearing end.
The inwall of the outer wall of the raised annular circle on described dust cover and described MC nylon pulley body endoporus is bumped into installation, and the cover plate of dust cover is connected and fixed by bolt and described MC nylon pulley body, and described dust cover is made by plastics or metalwork.
Described Waste oil discharger is arranged in raised annular circle on dust cover.
The Waste oil discharger that increases in the utility model and pouring orifice form the circulating notes heat-extraction system of grease; reach and approach the effect of changing grease; greatly reduce bearing rate of fault, reduced noise, so the circulating notes heat-extraction system of grease plays protection, guaranteeing role to the ride quality of bearing and even structure.Dust cover is bumped into the bearing end that is fixed on the pulley both sides by the raised annular circle, inset type is installed and is fixedly connected with the dislocation in case assemblying body skids relatively.The utlity model has following superiority: simple in structure, easily produce; Avoid bearing due to impurity or sump oil produce than galling and noise; Ensure the sense of human body ride comfort; Reduce rate of fault and the turnover rate of overall operation mechanism.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A section structure for amplifying schematic diagram in Fig. 1;
In figure: 1 pouring orifice, 2 grease-proof side leakage devices, 3 Waste oil dischargers, 4 bolts, 5 circlips, 6 MC nylon pulley bodies, 7 raised annular circles, 8 bearings, 9 oil-hole plugs.
Embodiment
The circulating MC nylon pulley of grease, comprise MC nylon pulley body 6, be placed in MC nylon pulley body endoporus bearing 8, be arranged on pouring orifice 1 on MC nylon pulley body and the dust cover of pulley both sides bearing end.
The bearing end of pulley both sides is respectively equipped with the grease-proof side leakage device 2 that communicates with MC nylon pulley body endoporus.Dust cover is made by plastics or metalwork, and raised annular circle 7 is set on dust cover, and dust cover is bumped into the bearing end formation grease-proof side leakage device that is fixed on the pulley both sides by the raised annular circle.The inwall of the outer wall of the raised annular circle on dust cover and MC nylon pulley body endoporus is bumped into installation, and the cover plate of dust cover is connected and fixed by bolt and MC nylon pulley body.
Dust cover is provided with oil drainage hole and oil-hole plug 9 consists of Waste oil discharger 3.Waste oil discharger is arranged in raised annular circle on dust cover.Waste oil discharger and pouring orifice form the circulating notes heat-extraction system of grease.
Also be provided with the circlip of at least one rigid bearing in MC nylon pulley body endoporus, circlip is arranged on the bearing end.
The utility model can add grease by pouring orifice 1 in use, only need open the oil-hole plug 9 on Waste oil discharger 3 when needing discharging sump oil or chip impurity.
Claims (4)
