Abstract
The utility model relates to a clamping opening type grease circulation monomer casting (MC) nylon pulley, in particular to a clamping opening type grease circulation MC nylon pulley structure. The clamping opening type grease circulation MC nylon pulley comprises an MC nylon pulley, a pulley shaft, bearings and a circulation grease injection and discharge system, wherein the pulley shaft and the bearings are arranged in an inner hole of the MC nylon pulley, and the circulation grease injection and discharge system is formed by dust covers arranged at the ends of the bearings on two sides of the MC nylon pulley, an oil filling port arranged on the MC nylon pulley and waste oil discharging devices arranged on the dust covers. The clamping opening type grease circulation MC nylon pulley is characterized in that an annular protruded block is arranged on the outer edges of the dust covers, a chamfer is arranged on the inner side of the annular protruded block, an annular groove matched with the annular protruded block is arranged on the inner edge of an orifice of the inner hole of the MC nylon pulley, the dust covers are embedded, clamped and fixed through the annular protruded block and the annular groove to form a clamping opening type grease side leakage prevention device. The waste oil discharging devices, the oil filling port and the clamping opening type grease side leakage prevention device form the clamping opening type circulation grease injection and discharge system, effect of being close to grease replacement is achieved, noises are lowered, and the failure rate and the replacement rate of an overall running mechanism are reduced.
Description
Technical field
The utility model relates to a kind of body structure of taking turns, and is 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.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of and can protect bearing and motion, prolongs its working life, reduces the clamping-type grease circulation MC nylon pulley of noise and rate of fault.
The purpose of this utility model is 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 in the utility model; 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 utlity model has following superiority: simple in structure, easily produce, 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.
