Background technology
Ribbon conveyer and digging special-purpose loading machine, belt type conveying mechanism generally use bearing fitted outside bend pulley,
Since its bearing is outside, unavoidably it is subject to the erosion of dust and moisture content, it is necessary to carry out the days such as cleaning and grease up
Often safeguard.And bearing is prone to wear out, and causes operating noise larger, belt operation unstability, sideslip increase equipment failure rate and maintenance
Cost.
The content of the invention
To overcome the technical deficiency of existing bearing fitted outside bend pulley, the goal of the invention of the utility model is to provide one
Kind bearing built-in type bend pulley, is corroded to avoid bearing be subject to dust and moisture content.
To realize above-mentioned purpose of utility model, the utility model bearing block is placed in the both ends of cylinder, with barrel soldering into one
Body；Bearing is installed in bearing block, and the bearing internal surface of hole cooperation of outer ring and bearing block, inner ring is set in the bearing neck of drum shaft
Position outer round surface；Bearing cap is installed on the outside of bearing block by holding screw；Sealing ring is packed into the seal groove of bearing cap；
Grease nipple is screwed into the threaded hole of bearing cap；Bearing built-in type bend pulley passes through two end milling face of drum shaft and ribbon conveyer
Structure connection is fixed.
The cylinder is using smooth finish surface or carries out annular knurl processing, can also coat plastic layer and the table in plastic layer
Face carries out annular knurl processing.
The cylinder is tubular structure, and cylinder is provided at both ends with the seam allowance positioned for bearing block welding.
It is provided on the inside of the bearing block for the interior flange collar of side positioning in bearing outer ring, bearing block outside is provided with tight
Determine screw thread hole.
The bearing cap carries seal groove, and side positioning and axial direction outside the inner ring for bearing are provided on the inside of bearing cap
The flange collar of clearance adjustment, there is the installation threaded hole for setting holding screw connecting hole and grease nipple on bearing cap.
The drum shaft is using intermediate structure thick, both ends are thin, and the mounting neck position size of bearing is less than stage casing, more than two
End forms the convex shoulder of the interior side positioning for bearing inner race between intermediate thick part and bearing mounting neck position, drum shaft
Both ends are milled into plane.
Compared with prior art, using bearing built-in type bend pulley, bearing is in sealing state to the utility model, with
External environment is sealed isolation, is corroded to avoid bearing be subject to dust and moisture content, can effectively alleviate bearing wear, reduces fortune
Row noise increases operation stability, and need not carry out the regular maintenances such as cleaning and grease up, realizes that roller operation exempts to tie up
Shield reduces operation and maintenance cost.
