Abstract
The utility model relates to a bearing seat for a belt roller. The utility model provides a high-precision bearing seat which has good seal, flexible running, long service life and low cost and is characterized in that the bearing seat is in a flange-plate shape; a bearing, a sealing ring and a check ring are orderly arranged in a seat bore; the flange-face edge of the bearing seat is provided with an extraversive arc-shaped edge. The utility model has few parts and reduces production cost; the check ring is used to assemble the parts into a whole body by one-step precise stamping, and the production efficiency and the assembling quality are enhanced; the utility model has good sealing property, and the service life is increased by three to four times.
Description
Technical field
The utility model relates to the conveyer carrying roller bearing seat.
Background technology
Existing conveyer carrying roller cast bearing seat, own wt is big, adopts a cover nylon labyrinth seal sealing, poor sealing performance, bearing is non-anti-theft; Bearing seat adopts hand assembly to form by seven, eight parts, and product quality is low; Existing bearing seat only depends on a cover nylon labyrinth seal sealing in the bearing outside, and poor sealing performance advances dirt easily, causes the bearing corrosion, increases rotational resistance, enhance faster wear, service life weak point, at most half a year some months at least;
Summary of the invention
The purpose of this utility model is: a kind of good seal is provided, goes slick, long service life, high-precision bearing seat that cost is low.
The structural design scheme of realizing the foregoing invention purpose is as follows:
The high-precision bearing seat comprises bearing seat, bearing, seal ring and ring washer, it is characterized in that: described bearing seat is the flange plate-like, and seat is provided with bearing, seal ring and ring washer in the hole successively; Bearing block flange face edge is provided with the arc limit of turning up; Described seal ring is a multilayer words urethane seal circle.
High-precision bearing seat according to above-mentioned is characterized in that: described multilayer words urethane seal circle madial wall is provided with three sealing bulge loops, and the axial cross section of sealing bulge loop is down bell mouth shape.
High-precision bearing seat according to above-mentioned is characterized in that: described bearing seat seat hole depth is the 30-45 millimeter.
Useful technique effect of the present utility model is embodied in several aspects:
1, structure design of the present utility model has reduced number of parts, only needs four parts, has reduced productive costs, labor and material saving.
2, bearing seat seat hole depth of the present utility model is more shallow 1/3 than prior art, uses ultra-thin serial bearing, adopts precision stamping of back-up ring to be assembled into an integral body, has changed existing many cover hand assembly technologies, has improved production efficiency and assembly quality.
3, adopt multilayer words urethane seal circle, sealing is tight, can prevent the intrusion of dust and water smoke effectively, has guaranteed oil storage lubricating condition in the bearing bore, and raising 3-4 in service life doubly.
When 4, the utility model is used for roller carrier shaft bearing on the conveyer, do not need to adopt weld-on installation, the flange design of bearing seat makes it to adopt the cold stamping assembling, has guaranteed the carrying roller smooth outer surface, in the use load-transfer device is difficult for producing plucking and damages the service life of having improved load-transfer device.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
The high-precision bearing seat comprises bearing seat 1, bearing 2, seal ring 3 and ring washer 4.Bearing seat 1 is the flange plate-like, and bearing seat seat hole depth is the 30-45 millimeter, and seat is equipped with bearing 2, seal ring 3 and ring washer 4 in the hole successively; 4 precision stampings of ring washer hole of packing into forms a whole with bearing seat 1; Bearing seat 1 flange face edge is the arc limit of turning up; Seal ring 3 is a multilayer words urethane seal circle, and multilayer words urethane seal circle madial wall has three sealing bulge loops, and the axial cross section of sealing bulge loop is down bell mouth shape.
