Abstract
The invention discloses an oil-circulating type MC (Monomer Casting) nylon pulley and in particular relates to a structure of the oil-circulating type MC nylon pulley. The oil-circulating type MC nylon pulley comprises an MC (monomer casting) nylon pulley body, a bearing, dustproof covers and an oil filling 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 two sides of the pulley; and the oil filling port is formed in the MC nylon pulley body; the oil-circulating type MC nylon pulley is characterized in that the bearing ends on the two sides of the pulley are respectively provided with an oil lateral leakage preventing device which is communicated with the inner hole of the MC nylon pulley body; bulged annular rings are arranged on the dustproof covers; the dustproof covers are arranged and fixed at the bearing ends on the two ends of the pulley in an embedding manner through the bulged annular rings to form the oil lateral leakage preventing device; oil outlets and oil hole plugs are formed in the dustproof covers to form a waste oil discharging device; and the waste oil discharging device and the oil filling pot form an oil-circulating type discharging-filling system. The oil-circulating type MC nylon pulley has the advantages of being simple in structure and easy to product, preventing the bearing from generating large abrasion and noise caused by impurities or waste oil, guaranteeing the riding comfort of the body, and reducing the failure rate and the exchange rate of an integral operating mechanism.
Description
Technical field
The present invention relates to a kind of Wheel structure, be specifically related to the structure of the circulating MC nylon pulley of a kind of grease.
Background technique
The MC nylon pulley that adopts in elevator industry, oilfield machinery field, the bearing that pulley train center moves 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.Unusually the monolithic wheel system that brings of bearing produces fault, and the unusual 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.
Summary of the invention
The objective of the invention is for above-mentioned the deficiencies in the prior art, provide a kind of and can protect bearing and motion, prolong its working life, reduce the circulating MC nylon pulley of grease of noise and rate of fault.
The objective of the invention is to be achieved through the following technical solutions: the circulating MC nylon pulley of grease, comprise MC nylon pulley body, place the bearing of MC nylon pulley body endoporus, the dust cover of pulley both sides bearing end and be arranged on pouring orifice on the 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 the described dust cover, dust cover is bumped into the bearing end that is fixed on the pulley both sides by the raised annular circle and consists of grease-proof side leakage device, and 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 the 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 the 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 the raised annular circle on the dust cover.
The Waste oil discharger that increases among the present invention 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 present invention has following superiority: simple in structure, easily produce; Avoid bearing owing 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 invention;
Fig. 2 is A section structure for amplifying schematic diagram among Fig. 1;
Among the 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, place MC nylon pulley body endoporus bearing 8, be arranged on pouring orifice 1 on the 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 the dust cover, and dust cover is bumped into the bearing end that is fixed on the pulley both sides by the raised annular circle and consists of grease-proof side leakage device.The inwall of the outer wall of the raised annular circle on the 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 the raised annular circle on the 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 the MC nylon pulley body endoporus, circlip is arranged on the bearing end.
The present invention can add grease by pouring orifice 1 in use, only need open the oil-hole plug 9 on the Waste oil discharger 3 when needing discharging sump oil or chip impurity.
