Abstract

The utility model discloses a top roller bearing belongs to the spinning machine manufacturing technology, include: dabber, outer lane, steel ball, end cover, keep ware, seal assembly. This seal assembly comprises sealing element A and sealing element B contains the oil storage space in, overcome traditional top roller bearing dust ring position overflow drain grease adhesion filoplume, debris, often take place greasy dirt yarn and cotton twine to the bearing can not rotate, yarn downgrade scheduling problem, has saved a large amount of cleannesses and has safeguarded the recruitment, lengthened bearing life, improved the yarn quality.

Description

Upper roller bearing

Technical field：

This utility model relates generally to thread spinner special parts manufacturing technology field, and more particularly to a kind of upper roller bearing

Background technology

Upper roller bearing plays yarn drafts, draw in spinning machinery, assembles inside traditional upper roller bearing outer ring There is metal dust circle, on outer ring, set is formed with aluminium inserted cot, adds enough before use into bearing by end cover tank filler sleeve Lubricant grease, oils and fatss overflow through dust ring, can adhere to filoplume, debris, often occur greasy dirt yarn and Cotton Gossypii to be wound to bearing not The problems such as energy rotates, yarn qualities decline.For the various problems avoiding oil spilling to cause, some spin enterprise when refueling, in bearing Oiling deficiency, frequent generation steel ball and rolling body region oil-free are easy to wear, the problem of the lost of life, yarn qualities decline.Above-mentioned Situation long-standing problem spins enterprise, in the industry all to strengthen sealing effectiveness as improvement direction, but can not rotate flexible base ensureing bearing Realize on plinth fully sealing, the situation long-term existence that micro oil spilling impact produces, the cleaning amount of labour used is big, high cost, yarn The problems such as Quality Down, is difficult to solve.

Content of the invention

Technical problem to be solved in the utility model is to provide one kind to have " potted component A and potted component B composition The upper roller bearing of novel sealing component structure " (such as Figure of description, hereinafter referred to as black box).

This utility model technical problem is achieved through the following technical solutions：

1. a kind of upper roller bearing includes mandrel, outer ring, steel ball, end cap, keeper, black box.The institute of described bearing State black box to be made up of potted component A profit potted component B, include storage oils and fatss space.

2. black box described in above-mentioned upper roller bearing, wherein potted component A and outer ring interference fit, with mandrel gap Cooperation, potted component B and mandrel interference fit, with the cooperation of outer ring gap.

3. black box described in above-mentioned upper roller bearing, wherein potted component A and outer ring interference fit, with mandrel gap Cooperation, potted component B and outer ring interference fit, with the cooperation of mandrel gap.

4. black box described in above-mentioned upper roller bearing, wherein potted component A and mandrel interference fit, with outer ring gap Cooperation, potted component B is coordinated with mandrel gap, with outer ring interference fit.

5. black box described in above-mentioned upper roller bearing, wherein potted component A and mandrel interference fit, with outer ring gap Cooperation, potted component B and mandrel interference fit, with the cooperation of outer ring gap.

6. black box described in above-mentioned upper roller bearing, potted component A has oil storage space.

7. black box described in above-mentioned upper roller bearing, potted component B has oil storage space.

8. black box described in above-mentioned upper roller bearing, has oil storage space between potted component A and potted component B.

9. black box described in above-mentioned upper roller bearing, potted component A is coordinated with mandrel maximum gauge position, sealing unit Part B is coordinated with mandrel maximum gauge position.

10. black box described in above-mentioned upper roller bearing, potted component A is coordinated with mandrel non-maximum gauge position, close Envelope element B and mandrel maximum gauge position coordinate.

Compared with prior art：This utility model bearing is sealed with black box, on the one hand enhances sealing effectiveness, On the other hand increased oil storage space, in the case of oils and fatss abundance in bearing, clean oil-free outside black box, solve biography The existing problems of system upper roller bearing, save substantial amounts of cleaning recruitment, extend bearing service life, improve yarn Quality.

Brief description

Fig. 1 be this utility model product structure 1 (potted component A is coordinated with mandrel maximum gauge position, potted component B with Mandrel maximum gauge position coordinate) schematic diagram (and 1. end cap 2. outer ring 3. steel ball 4. potted component A 5. oil storage space is 6. close Envelope element B 7. mandrel)

Fig. 2 is that (potted component A is coordinated this utility model product structure 2 with mandrel non-maximum gauge position, potted component B With the cooperation of mandrel maximum gauge position) schematic diagram (1. end cap 2. outer ring 3. steel ball 4. potted component A 5. oil storage space is 6. Potted component B 7. mandrel)

Specific embodiments：

In conjunction with above-mentioned accompanying drawing embodiment, this utility model is described in detail again.

1. a kind of upper roller bearing includes mandrel, outer ring, steel ball, end cap, keeper, black box.Black box is by close Envelope element A and potted component B is constituted, and double-layer seal enhances sealing effectiveness；Black box includes storage oils and fatss space can be held Receive micro oil spilling, so that oil spilling cannot be reached outside potted component B.

The black box that this utility model upper roller bearing adopts, double-layer sealing structure is just than traditional upper roller bearing Oil-leakage-prevention effect good, along with black box is contained within oil storage space, micro excessive oils and fatss are stored in this oil storage space, enter one Step avoids outside the excessive B in potted component of oils and fatss.It is dust-proof that this utility model upper roller bearing avoids traditional upper roller bearing The various problems that circle part leakage oils and fatss are brought.
