Abstract
The invention discloses a rotor spinning frame leather roller bearing, which comprises an outer ring, a central spindle, a retainer, a rolling body, a sealing ring and an end cover, wherein the rolling body is installed between the outer ring and the central spindle; the retainer is isolated from the rolling body; the sealing ring is pressed on the excircle of the central spindle; the other end of the outer ring is provided with the end cover; the end cover is provided with an oil filling port; the outer ring is provided with a channel and an inner bore; and the outer ring is also covered with a leather collar. The rotor spinning frame leather roller bearing has simple, compact and reasonable structure. The leather roller bearing and the leather collar are integrated. The rotor spinning frame leather roller bearing can smoothly and stably operate to avoid machining errors caused by the secondary machining of the channel and the inner bore; and the channel and the inner bore can be machined and shaped at one time, thus machining working procedures are reduced, cost and time are saved, and the machining precision is greatly improved. Because the bearing of the structure integrally becomes large, the diameter of a steel ball correspondingly becomes large, and strength and abrasive resistance are improved.
Description
Technical field
The invention belongs to the textile workpiece technical field, be specifically related to a kind of roller bearing that is used on the rotor spinning machine.
Background technology
At present, the roller bearing that is used on the rotor spinning machine mainly is made up of outer ring, mandrel, retainer, rolling element (roller or ball), sealing ring, end cap etc.Be employed in rolling element (roller or ball) is installed between outer ring and the mandrel, and with the retainer location, retainer separation roller and maintenance rolling element proper exercise, sealing ring is pressed on the cylindrical of mandrel, and the bearing outer ring other end is equipped with end cap, has tank filler sleeve on it.The rotor spinning machine roller bearing outer ring processing raceway groove and the endoporus branch two procedures of this kind structure are carried out, and owing to the secondary clamping, can not effectively guarantee the concentricity of raceway groove and endoporus; Roller bearing and apron are not an integral body, and bearing outer ring and apron endoporus are matched in clearance, when bearing working, have increased beating of apron external diameter, have reduced precision.This kind structure diminishes bearing integral, and steel ball size is also corresponding little, has reduced intensity and ABRASION RESISTANCE.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point; A kind of rotor spinning machine roller bearing is provided, the mismachining tolerance of avoiding raceway groove and endoporus secondary operations to be caused, raceway groove and endoporus processing one-shot forming; Both reduced manufacturing procedure; Practice thrift cost and time, improved machining accuracy again greatly simultaneously, and can gain in strength and ABRASION RESISTANCE.
Main solution of the present invention is achieved in that
Rotor spinning machine roller bearing comprises outer ring, mandrel, retainer, rolling element, sealing ring, end cap, between described outer ring and the mandrel rolling element is installed; Described retainer separation roller; Described sealing ring is pressed on the cylindrical of mandrel, and the described outer ring other end is equipped with end cap, and described end cap is provided with tank filler sleeve; Described outer ring is provided with raceway groove and endoporus, also is enclosed with apron on the described outer ring.
The length of described endoporus is: 2～10mm.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Roller bearing and apron are as a whole; The mismachining tolerance that smoothly steadily can avoid raceway groove and endoporus secondary operations to be caused during running, raceway groove and endoporus time processing are shaped, and have both reduced manufacturing procedure; Practice thrift cost and time, improved machining accuracy simultaneously again greatly; Become big because this kind airframe bearing is whole, make the strain of steel ball size phase big, increased intensity and ABRASION RESISTANCE.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an outer ring structure sketch map of the present invention.
Sequence number among the figure: 1, apron, 2, the outer ring, 3, mandrel, 4, retainer, 5, rolling element, 6, sealing ring, 7, end cap, 8, cylindrical, 9, tank filler sleeve, 10, raceway groove, 11, endoporus.
The specific embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
Referring to Fig. 1 and a kind of rotor spinning machine roller of Fig. 2 bearing; Comprise outer ring 2, mandrel 3, retainer 4, rolling element 5, sealing ring 6, end cap 7, rolling element 5, described retainer 4 separation rollers 5 are installed between described outer ring 2 and the mandrel 3; Described sealing ring 6 is pressed on the cylindrical 8 of mandrel 3; Described outer ring 2 other ends are equipped with end cap 7, and described end cap 7 is provided with tank filler sleeve 9, and described outer ring 2 is provided with raceway groove 10 and endoporus 11; Also be enclosed with apron 1 on the described outer ring 2, the length of described endoporus 11 is: 2～10mm.
The present invention is employed in rolling element 5 is installed between outer ring 2 and the mandrel 3, and its size and quantity directly have influence on the load-carrying ability of bearing; Retainer 4 even separation rollers 5 and maintenance rolling element 5 proper exercises improve the bearing internal load and distribute and greasy property; Sealing ring 6 is pressed on the cylindrical 8 of mandrel 3, has guaranteed not have foreign material to get into bearing inside and has prevented that simultaneously grease from leaking outside.Outer ring 2 other ends are equipped with end cap 7, have tank filler sleeve 9 on it, are convenient to the bearing grease of in use can annotating again, also can play dustproof simultaneously and prevent the effect that grease leaks outside.
Rotor spinning machine roller design bearing of the present invention becomes unique double channel ball bearing, and the load of carrying is light, guarantees its high efficiency with high-precision external form and level and smooth running.Outer ring 2 is provided with raceway groove 10 and adds with endoporus 11 mills and connect raceway groove 10 and endoporus 11 disposable machine-shapings man-hour, and the length of endoporus 11 is: 2～10mm, apron 1 directly are wrapped on the outer ring 2 of rotor spinning machine roller bearing, and making it is an integral body.This kind frame mode can guarantee the mismachining tolerance that the footpath, the end of raceway groove 10 and endoporus 11 has avoided raceway groove 10 and endoporus 11 secondary operations to be caused in claimed range; Raceway groove 10 and endoporus 11 disposable machine-shapings; Both reduced manufacturing procedure; Practice thrift cost and time, improved machining accuracy simultaneously again; Because this structure makes bearing integral become big, make rolling element 5 diameters become big, increased intensity and ABRASION RESISTANCE simultaneously again.
Embodiment is just for the ease of understanding technical scheme of the present invention; Do not constitute restriction to protection domain of the present invention; Every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present invention above scheme being done that does not break away from technical scheme of the present invention all still belongs within the protection domain of the present invention.
