Abstract
The invention relates to a special bearing for a chemical fiber winder. The special bearing comprises an outer ring, an inner ring, a retainer and rolling elements, wherein the outer ring is processed by a roller sleeve of a winding head of the chemical fiber winder, two corresponding rolling tracks are processed between the roller sleeve and the inner ring, and the rolling elements in two rows are respectively arranged in the two rolling tracks. According to the special bearing provided by the invention, the bearing and the winding head of the chemical fiber winder are integrally designed, so that processing errors and assembling errors are reduced, the precision of the bearing can reach a grade P4, and the service life of the bearing is prolonged to more than one year.
Description
Technical field
The present invention relates to bearing, specifically a kind of chemical fibre up-coiler special bearing that is used for chemical fiber machinery.
Background technique
Chemical fibre up-coiler special bearing mainly is assemblied in the two ends of high speed winding head.In the chemical fibre spinning equipment, wrapping head is one of the most key unit machine.Wrapping head is to be used for being convenient to the product that next procedure is used with being wrapped in paper tube regularly from the spun tow of spinneret 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 chemical fibre spinning equipments all adopt all steel bearing idler pulley from external import at present, and its structure is as shown in Figure 1, is made up of drum sleeve 1, rolling bearing 2 and 3, cone spacer 4.Bearing 2 is fitted on the drum sleeve 1 with bearing 3, and cone spacer 4 is used between the inner ring of two bearings 2,3 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 having only half a year in working life of bearing 2,3.It is big that tens cylinders of whole unit are all pulled down back replacing bearing working amount, had a strong impact on productivity effect.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of chemical fibre up-coiler special bearing that is used for the high speed chemical fiber machinery is provided, this bearing can improve the precision of whole cylinder, and long service life.
According to technological scheme of the present invention: a kind of chemical fibre up-coiler special bearing; Comprise outer ring, inner ring, retainer and rolling element; Said outer ring is processed by the wrapping head drum sleeve of said chemical fibre up-coiler; Be processed with corresponding pair of ditch raceway between said drum sleeve and the said inner ring, said rolling element has two row, is installed in respectively in the said pair of ditch raceway.
The material of said drum sleeve and said inner ring is the GCr15 Bearing Steel, and the material of said retainer is PEEK, and said rolling element is a ceramic ball.
Be respectively arranged with seal ring between the two ends of said inner ring and the said drum sleeve.
The two ends of said drum sleeve inwall are respectively arranged with swings to the angle.
Said angle of swinging to the angle is 20 °.
The middle part of said inner ring endoporus is provided with the emery wheel groove.
Technique effect of the present invention is: the present invention has reduced machining error and assembly error with the wrapping head integrated design of bearing and chemical fibre up-coiler, 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 a ceramic ball, and this selection has further improved the working life of bearing.
Description of drawings
Fig. 1 is the erection drawing of former chemical fibre up-coiler roller assemblies.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is the structural representation of the bearing outer ring among the present invention.
Fig. 4 is the structural representation of the bearing inner race among the present invention.
Embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Among Fig. 1～Fig. 4, comprise drum sleeve 1, bearing 2, bearing 3, cone spacer 4, inner ring 5, retainer 6, rolling element 7, seal ring 8 etc.
As shown in Figure 2, the present invention is a kind of chemical fibre up-coiler special bearing, comprises outer ring, inner ring 5, retainer 6 and rolling element 7.
The present invention is a kind of conjuncted bearing, and the wrapping head drum sleeve 1 of its bearing outer ring and chemical fibre up-coiler is processed by drum sleeve 1 for one designs.Be processed with corresponding pair of ditch raceway 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 fibre up-coiler 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.
Drum sleeve 1 is the GCr15 Bearing Steel with the material of inner ring 5, and the material of retainer 6 is PEEK (Polyether Ether Ketone, a polyether-ether-ketone resin), and rolling element 7 is a ceramic ball.This selection has further improved the working life of bearing.
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 help 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 on the outer wall of inner ring 5 and 1 pair of ditch raceway of drum sleeve e, corresponding pair of ditch raceway of f g, h.The middle part of inner ring 5 endoporus also is provided with emery wheel groove k, helps the raising of bearing inner race 5 endoporus mill machining accuracy like this.
Retainer 6 is interior guide structure design, and the guide clearance at the endoporus of retainer 6 and inner ring 5 external diameter L positions is 0.4.
