Abstract

Disclosed is a bearing in use for high speed spinning winding machine, which an outer ring 1, an inner ring 2, balls 3 and a holder 4. The utility model is characterized in that the clearance gap of the bearing ball is the clearance gap of the balls and the inner ring or the clearance gap of the balls and the outer ring, and the maximum clearance gap is 0.03 millimeter-0.1 millimeter; the holder is made of the nylon 1010, and the lubricating grease with high degree of viscosity is adopted. The utility model has the advantages of long service life, favorable abrasive resistance and low noise.

Description

Bearing in use for high speed spinning winding machine

The utility model belongs to bearing, particularly the bearing on the high-speed spinning up-coiler.

Be used for the bearing on the high-speed spinning up-coiler, because the bearing ball gap is less than 0.01 millimeter, be that the bearing ball gap refers to the maximal clearance between ball and inner ring, the outer ring, bearing can only be with the little lubricating grease of viscosity, bearing at a high speed and the elevated temperature heat that produces in the long-time running expand and make bearing use hundreds of hour just very fast scaling loss.

The purpose of this utility model provides a kind of long service life, and the bearing ball gap is big, can effectively overcome bearing and produce the bearing that elevated temperature heat expands at a high speed and in the long-time running.

The utility model is to realize like this, bearing on the high-speed spinning up-coiler is by inner ring, the outer ring, ball, retainer is formed, the inner ring of bearing, the outer ring, ball is iron or steel, the bearing ball gap minimum of bearing is 0.03 millimeter, be 0.1 millimeter to the maximum, in order to reduce the vibrating noise that produces greatly owing to the bearing ball gap, the retainer of bearing can be used nylon 1010 material system, to reduce noise, in order to guarantee running up of bearing, per minute 10000 changes and 10000 hours continuous running, bearing should adopt the big and good lubricating grease of temperature tolerance of viscosity, to prolong the working life of bearing, adopt the bearing of this structure, reach 11000 hours working life.

Fig. 1 is a sectional view of the present utility model

1. outer rings, 2. inner rings, 3. balls, 4. retainers wherein

Now in conjunction with the accompanying drawings the utility model is further described.

Bearing is made up of outer ring (1), inner ring (2), ball (3), retainer (4), the outer ring of bearing (1), inner ring (2), ball (3) are steel, retainer (4) is made by the nylon 1010 material, the optimum size in bearing ball gap is 0.03mm to 0.05mm, for increasing the working life of bearing, the lubricating grease of bearing adopts the big lubricating grease of viscosity, adopts the bearing of this structure, has generally prolonged the working life of bearing.

The utility model has prolonged the service life of bearing greatly owing to adopt this structure, and it is good to have wearability, the advantage that noise is little.

Claims

1, a kind of bearing that is used on the high-speed spinning up-coiler is made up of outer ring 1, inner ring 2, ball 3, retainer 4, it is characterized in that the bearing ball gap is 0.03 millimeter to 0.1 millimeter.
