Abstract
The invention relates to an insert type MC (Methyl Cellulose) nylon pulley of a knurling bush, and in particular relates to a structure of an MC nylon pulley. The insert type MC nylon pulley comprises an MC nylon pulley body, a bearing arranged in an inner hole of the MC nylon pulley body, and the knurling bush arranged between the inner hole of the MC nylon pulley body and the bearing. The pulley is characterized in that the knurling bush and the inner hole of the MC nylon pulley body are concentric, and the knurling bush is fixedly inlaid and installed in the inner hole of the MC nylon pulley body; and the inner hole of the MC nylon pulley body is at least provided with one elastic retaining ring for fixing the bearing, and the elastic retaining ring is placed between the knurling bush and the bearing through a groove formed in the knurling bush. According to the pulley provided by the invention, the effect of prompting the production efficiency and stabilizing the structure is realized, the difficulty of assembly process is reduced, and the product precision is improved; and the production precision is ensured, and the assembly is convenient and the cost of the pulley is lowered, so that the purpose of efficient production is realized, the failure rate of the bearing is greatly reduced, and the noise is reduced.
Description
Technical field
The present invention relates to a kind of Wheel structure, be specifically related to a kind of structure of inset type annular knurl lining MC nylon pulley.
Background technique
The MC nylon pulley that in elevator industry, oilfield machinery field, adopts, no matter counterpart with MC nylon in the train is that bush type also is that non-bush type adopts the flange-type bolt to fix more or circlip is fixed, this structure influence manufacturing efficiency and Product Precision, cost is higher, latter's structural instability.Because flange lining and MC nylon pulley processing quality of fit are poor, cause whole train not satisfy customer demand, scrappage is high; Because the noise effect ride comfort sense that the structural instability factor produces.Therefore, existing MC nylon pulley is changed that difficulty is large, cost is high, has been reduced working life, causes the elevator user cost to improve.
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 guarantee Product Precision and stability, increase the service life, reduce the inset type annular knurl lining MC nylon pulley of noise and rate of fault.
The objective of the invention is to be achieved through the following technical solutions: inset type annular knurl lining MC nylon pulley, comprise MC nylon pulley body, place MC nylon pulley body endoporus bearing, be arranged on the annular knurl lining between MC nylon pulley body endoporus and the bearing, it is characterized in that, described annular knurl lining is concentric with MC nylon pulley body endoporus, and the annular knurl lining is bumped into and is fixed in the MC nylon pulley body endoporus; Described annular knurl lining endoporus is provided with the circlip of a rigid bearing at least, and described circlip places between annular knurl lining and the bearing by the groove that is arranged on the annular knurl lining.
The gluing connection between described annular knurl lining and the MC nylon pulley body.
Described annular knurl lining is that metalwork is made.
The invention reside in a kind of MC nylon pulley that can protect bearing and motion, long service life, reduction cost, efficient stable of design.The annular knurl lining is bumped into and is fixed on the dislocation in case assemblying body radially skids in the MC nylon pulley body endoporus among the present invention, anti-radial rotating; Gluingly between annular knurl lining and the MC nylon pulley body be connected anti-axial float.The present invention reaches and has promoted manufacturing efficiency and constitutionally stable effect, reduce the difficulty of assembly technology, improved Product Precision, can guarantee the precision of product, convenient for assembly, reduction cost, produce efficient purpose thereby reach, greatly reduce bearing rate of fault, reduced noise.The present invention also has following superiority: simple in structure, easily produce; Reduce cost; Improve assembly precision; 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;
Among the figure: 1 MC nylon pulley body, 2 circlips, 3 bearings, 4 annular knurl linings.
Embodiment
Inset type annular knurl lining MC nylon pulley, comprise MC nylon pulley body 1, place MC nylon pulley body endoporus bearing 3, be arranged on the annular knurl lining 4 between MC nylon pulley body endoporus and the bearing, the annular knurl lining is that metalwork is made.
The annular knurl lining is concentric with MC nylon pulley body endoporus, and the annular knurl lining is bumped into and is fixed in the MC nylon pulley body endoporus.Annular knurl lining endoporus is provided with the circlip 2 of a rigid bearing at least, and circlip places between annular knurl lining and the bearing by the groove that is arranged on the annular knurl lining, the gluing connection between annular knurl lining and the MC nylon pulley body.
Claims (3)
1. inset type annular knurl lining MC nylon pulley, comprise MC nylon pulley body, place MC nylon pulley body endoporus bearing, be arranged on the annular knurl lining between MC nylon pulley body endoporus and the bearing, it is characterized in that, described annular knurl lining is concentric with MC nylon pulley body endoporus, and the annular knurl lining is bumped into and is fixed in the MC nylon pulley body endoporus; Described annular knurl lining endoporus is provided with the circlip of a rigid bearing at least, and described circlip places between annular knurl lining and the bearing by the groove that is arranged on the annular knurl lining.
2. inset type annular knurl lining MC nylon pulley according to claim 1 is characterized in that, the gluing connection between described annular knurl lining and the MC nylon pulley body.
