Abstract
The utility model relates to a special axletree for a chemical fiber coiler. The special axletree for the chemical fiber coiler comprises an outer ring, an inner ring, a holder and a rolling body, wherein the outer ring is formed by processing a coiler head cylinder sleeve of the chemical fiber coiler. A corresponding two-duct raceway is processed between the cylinder sleeve and the inner ring, and two lines of rolling parts are respectively installed in the two-duct raceway. The special axletree for the chemical fiber coiler has the advantages of integrally designing the axletree and the coiler head of the chemical fiber coiler, reducing processing error and assembling error, achieving P4 grade in precision of the axletree, and increasing service lift to more than a year.
Description
Technical field
The utility model relates to bearing, specifically a kind of chemical fiber winding machine special bearing for chemical fiber machinery.
Background technique
The chemical fiber winding machine special bearing mainly is assemblied in the two ends of high speed winding head.In Spinning Equipments, wrapping head is one of the most key unit machine.Wrapping head is for being wrapped in regularly paper tube from the spun tow of spinneret, and being convenient to the product that next procedure is used with formation.
The working speed of chemical fibre high speed winding head cylinder is 10800 r/min, and operating temperature is about 100 ℃, and work loads is variable load.Domestic a lot of Spinning Equipmentss all adopt the all-steel bearing idler pulley from external import at present, and its structure is comprised of drum sleeve 1, rolling bearing 2 and 3, cone spacer 4 as shown in Figure 1.Bearing 2 and bearing 3 are fitted on the drum sleeve 1, and cone spacer 4 is used between two bearings 2,3 the inner ring and does separation sleeve, has formed assembly parts.Because drum sleeve 1 is Vehicle Processing, both ends of the surface bearing hole concentricity precision is very poor; Adding is an assembled group component, and the overall accuracy after the assembling is poorer, thereby causes bearing 2, working life of 3 to only have half a year.It is large that tens cylinders of whole unit are all pulled down rear replacing bearing working amount, had a strong impact on productivity effect.
Summary of the invention
The utility model provides a kind of chemical fiber winding machine special bearing for the high speed chemical fiber machinery for the problems referred to above, and this bearing can improve the precision of whole cylinder, and long service life.
According to the technical solution of the utility model: a kind of chemical fiber winding machine special bearing, comprise outer ring, inner ring, retainer and rolling element, described outer ring is processed by the wrapping head drum sleeve of described chemical fiber winding machine, be processed with corresponding two ditch raceways between described drum sleeve and the described inner ring, described rolling element has two row, is installed in respectively in the described pair of ditch raceway.
The material of described drum sleeve and described inner ring is the GCr15 Bearing Steel, and the material of described retainer is PEEK, and described rolling element is ceramic ball.
Be respectively arranged with seal ring between the two ends of described inner ring and the described drum sleeve.
The two ends of described drum sleeve inwall are respectively arranged with swings to the angle.
Described angle of swinging to the angle is 20 °.
The middle part of described inner ring endoporus is provided with the emery wheel groove.
Technique effect of the present utility model is: the utility model has reduced machining error and assembly error with the wrapping head integrated design of bearing and chemical fiber winding machine, and the precision of bearing can reach the P4 level, can bring up to working life more than 1 year; The material of drum sleeve and inner ring is the GCr15 Bearing Steel, and the material of retainer is PEEK, and rolling element is ceramic ball, and this selection has further improved the working life of bearing.

The utility model is a kind of conjuncted bearing, and the wrapping head drum sleeve 1 of its bearing outer ring and chemical fiber winding machine is integrated design, is processed by drum sleeve 1.Be processed with corresponding two ditch raceways between drum sleeve 1 and the inner ring 5, rolling element 7 has two row, is installed in respectively in two ditch raceways, thereby forms double row bearing.Wrapping head integrated design with bearing and chemical fiber winding machine has reduced machining error and assembly error, and the precision of bearing can reach the P4 level, and can bring up to more than 1 year working life.
Also be respectively arranged with the seal ring 8 that seals between the two ends of inner ring 5 and the drum sleeve 1.
As shown in Figure 3, have groove at a, b, c position by customer requirements on the outer wall of drum sleeve 1, the d place, two ends of drum sleeve 1 inwall is provided with respectively swings to the angle, and the angle of swinging to the angle is 20 °.Swing to the angle and be conducive to the assembling of seal ring 8 and rolling element 7.Be processed with two ditch raceway e, f on the inwall of drum sleeve 1.
As shown in Figure 4, be processed with two ditch raceway gs, the h corresponding with 1 pair of ditch raceway of drum sleeve e, f on the outer wall of inner ring 5.The middle part of inner ring 5 endoporus also is provided with emery wheel groove k, is conducive to like this raising of bearing inner race 5 endoporus mill machining accuracy.
