Rolling groove both sides two small bearings in left side and two small bearings in right side are set respectively, the small bearing in two left sides and two right sides are small
The both ends of the small bearing in inner side of bearing are in contact with the inside of the first rolling plate and the second rolling plate respectively, two small bearings in left side
One end with the small bearing in outside of two small bearings in right side on the inside of the first rolling plate with being in contact, the other end and the second rolling plate
Inner side be not in contact with.
Further preferably, housing includes outer casing base and shell upper, and outer casing base and shell upper are consolidated by screw
It is fixed.Convenient installation.
Further preferably, baffle ring, two small axis in left side are set between the small bearing in two left sides or two small bearings in right side
Hold and shaft block ring is set in its front end after being installed on two small bearings in right side on roller shaft.Baffle ring can prevent that homonymy is two small
Friction between bearing, shaft block ring prevent coming off for bearing.
Further preferably, lower housing portion corresponds to arm shaft and sets end cap.Arm shaft is installed on lower housing portion, corresponding swing arm
Axis opens up mounting hole in housing both sides, and hull outside connection Electric Actuator is stretched out in arm shaft side, and opposite side sets end cap, prevents
Only dust enters in housing.
Beneficial effect is possessed by the present invention：
1st, permanent-magnet eddy current Flexible Transmission arrangements for speed regulation of the present invention can protect spline housing splined shaft from dust, rain
The erosion of snow, ensures normal operation and the use of speed adjusting gear, extends the service life of equipment.
2nd, permanent-magnet eddy current Flexible Transmission arrangements for speed regulation of the present invention, which slide original sliding block, promotes swing arm to make to transport toward Complex
It is dynamic, it is changed to bearing and rotates promote swing arm to make to move toward Complex, by improving, to reduce 1 sliding sleeve, the increase of 2 big bearing 4 small
Bearing, 7000 yuan to the greatest extent of cost reduction, installation time also shortens 4 hours, replace the time of bearing now only with 20 minutes, no
But the cost reduction of bearing portions is very much, and the service life of bearing also has original 2-3 to increase to 5-6.
