Bearing, articulated frame and sweeper

Abstract

The invention provides a bearing, a articulated frame and a sweeper. The bearing comprises a shaft sleeve, a connecting shaft, two plane bearings, an adjusting nut, a locking ring and a limiting piece; the connecting shaft penetrates through the shaft sleeve; a second axial end of the connecting shaft is provided with an external thread part and a limiting groove, the limiting groove extends in the axial direction, a first plane bearing is sleeved outside the connecting shaft, the first plane bearing is located between the limiting part and the shaft sleeve, a second plane bearing is arrangedoutside the connecting shaft in a sleeved mode, the adjusting nut is in threaded connection with the external thread part, the second plane bearing is located between the adjusting nut and the shaft sleeve, fixing holes are formed in the adjusting nut in the axial direction, the lock ring sleeves the connecting shaft, positioning holes re formed in the locking ring in the axial direction, a clamping block is arranged in the locking ring in the radial direction, the locking ring is located on the axial outer side of the adjusting nut, the clamping block is located in the limiting groove, and alimiting piece penetrates through the positioning holes to be connected with the fixing holes. The gap distance between the plane bearings and the shaft sleeve is adjusted through the adjusting nut, so that the performance of the bearing is improved, and equipment can operate more stably.

Description

technical field [0001] The invention relates to the field of new energy sanitation equipment, in particular to a bearing, an articulated vehicle frame and a sweeper. Background technique [0002] At present, common vacuum suction type floor sweepers on the market generally have wheels for driving along the ground, at least one rotatably driven sweeping brush for cleaning the ground, and a vacuum dustbin. Surfaces such as streets, sidewalks or parking lots can be swept with the help of this floor sweeper. At least one sweeping brush of the floor sweeper acts on the ground to be cleaned, and has the function of guiding the cleaning objects to the suction cup device, and the cleaning objects are sucked by the suction cup device and transported to the vacuum garbage bin through the pipeline connected thereto. [0003] Wherein, since the existing vehicle-type sweepers generally adopt an integral frame structure, the vacuum dustbin can be arranged in the rear area of ​​the vehicl...

AI Technical Summary

Problems solved by technology

The sweeping device and suction nozzle assembly are arranged in front of the driving direction of the vehicle frame, so a larger vehicle frame with a stronger load-bearing capacity must be used, which will cause inconvenient steering of the overall vehicle frame, inflexible walking and cleaning, and The overall frame has poor ability to cope with road conditions, resulting in unsatisfactory suction and sweeping performance of the sweeper
