Abstract
The invention provides a bayonet type grease circulating MC (Monomer Casting) nylon pulley, and particularly relates to a structure of the bayonet type grease circulating MC nylon pulley. The bayonet type grease circulating MC nylon pulley comprises a circulating grease filling and draining system which comprises an MC nylon pulley, a pulley shaft, a bearing, dust covers, an oil filling port and dirty oil draining devices, wherein the pulley shaft and the bearing are positioned in inner holes in the MC nylon pulley; the dust covers are arranged on the bearing ends at two sides of the MC nylon pulley; the oil filling port is formed in the MC nylon pulley; and the dirty oil draining devices are arranged on the dust covers. The bayonet type grease circulating MC nylon pulley is characterized in that annular bumps are arranged on the outer edges of the dust covers; chamfers are formed on the inner sides of the annular bumps; annular grooves in match with the annular bumps are positioned in the inner edges of ports of the inner holes in the MC nylon pulley; and the dust covers are fixed by embedding and clamping of the annular bumps and the annular grooves, thus forming a bayonet type grease side leaking preventing device. According to the bayonet type grease circulating MC nylon pulley, the dirty oil draining devices, the oil filling port and the bayonet type grease side leaking preventing device form the bayonet type circulating grease filling and draining system, an effect approaching to grease replacement can be realized, noises can be reduced, and the failure rate and the replacement rate of the whole operating mechanism can be reduced.
Description
Technical field
The present invention relates to a kind of body structure of taking turns, be specifically related to a kind of structure of clamping-type grease circulation MC nylon pulley.
Background technique
The MC nylon pulley that adopts in elevator industry, oilfield machinery field, the general employing of the bearing that pulley train center moves in a circle has a side dust cover (semiclosed) or both sides all have 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 big, has reduced the working life of bearing, and the elevator user cost improves.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, provide a kind of and can protect bearing and motion, prolong its working life, reduce the clamping-type grease circulation MC nylon pulley of noise and rate of fault.
The objective of the invention is to be achieved through the following technical solutions: clamping-type grease circulation MC nylon pulley, comprise the MC nylon pulley, place pulley spindle and the bearing of MC nylon pulley endoporus, the dust cover of MC nylon pulley two side bearing ends and be arranged on pouring orifice on the MC nylon pulley and dust cover on the circulating grease that constitutes of the discharging sump oil device that arranges annotate heat-extraction system, it is characterized in that, described dust cover outer rim is provided with annular lug, the annular lug inboard is provided with chamfering, the aperture inner edge of described MC nylon pulley endoporus is provided with the circular groove that is complementary with annular lug, and dust cover passes through annular lug, circular groove is inlayed to be fixed and is constituted clamping-type grease-proof side leakage device.
At least be provided with circlip or the boss of a rigid bearing on the described MC nylon pulley inner hole wall, circlip or boss are arranged on described bearing end.
Described pulley spindle is provided with retainer ring, and retainer ring squeezes and heads on the bearing outer end, and described retainer ring is inlaid in the ring recess that arranges on the pulley spindle.
The MC of institute nylon pulley inner hole wall is provided with annular groove, and described circlip or boss are bumped into and are fixed in the annular groove.
Described discharging sump oil device is made of screw, elastic sealing gasket and bolt plug.
Discharging sump oil device, pouring orifice, clamping-type grease-proof side leakage device form the circulation of clamping-type grease and annotate heat-extraction system among the present invention; reach and approach the effect of changing grease; greatly reduce bearing rate of fault, reduced noise, so clamping-type grease circulation is annotated heat-extraction system the ride quality of bearing and even structure is played protection, guaranteeing role.Dust cover is inlayed the bearing end that the engaging back-off is fixed on the pulley both sides by the chamfering of annular lug, circular groove, annular lug one side setting, and reverse buckling type connects in case clamping-type grease-proof side leakage device comes off.The present invention has following superiority: simple in structure, easily produce, and save cost; 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.
