Bearing with graphite copper sleeve, articulated frame and sweeper

Abstract

The invention provides a bearing with a graphite copper sleeve, an articulated frame and a sweeper. The bearing comprises a shaft sleeve, a connecting shaft, the graphite copper sleeve, a first planebearing, a first end cover, a second plane bearing and a second end cover, wherein the shaft sleeve is provided with a through hole along the axial direction in a penetrating way; the connecting shaftpenetrates through the through hole; the graphite copper sleeve is arranged in the through hole and sleeves outside the connecting shaft; the first plane bearing sleeves outside the connecting shaftand is arranged at the first axial end of the shaft sleeve; the connecting shaft penetrates through the first end cover; and the first end cover covers the outside of the first plane bearing and is fixed onto the first axial end of the shaft sleeve. The graphite copper sleeve is connected between the connecting shaft and the shaft sleeve, and a self-lubricating function of the graphite copper sleeve is utilized, so that the friction of the connecting shaft is effectively reduced; and meanwhile, the graphite copper sleeve has a high-efficiency heat-conducting performance, and the plane bearingsand the end covers are arranged at two axial end parts, so that the bearing is simple in structure.

Description

Technical field [0001] The invention relates to the field of new energy environmental sanitation equipment, in particular to a bearing with a graphite copper sleeve, an articulated frame and a sweeper. Background technique [0002] Currently, common vacuum suction floor sweepers on the market generally have wheels for running along the ground, at least one rotatably driven sweeping brush for cleaning the ground, and a vacuum dustbin. With the help of this floor sweeper, the ground can be cleaned, such as streets, sidewalks or parking lots. At least one sweeping brush of the floor sweeper acts on the ground to be cleaned, and has a device that guides the sweeping objects to a suction cup, and the sweeping objects are sucked by the suction cup device and transported to the vacuum waste bin through a pipe connected to it. [0003] Among them, since the existing vehicle-type sweeper generally adopts an integral frame structure, the vacuum trash can can be arranged in the rear area of ...

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

[0004] In order to improve the flexibility of the cleaning machine, a articulated frame was developed. The front frame and the rear frame are connected by bearings. Since the frame is not only subjected to the lateral impact force when turning, but also the longitudinal impact force Impact force, so a variety of different bearings are installed in the bearing, through the force conversion between different bearings, the impact force is converted and absorbed, which also leads to complex bearing structure and difficult maintenance
