Abstract
The utility model discloses a ground roll. The ground roll comprises a frame, a central shaft, a bearing cover, a baffle plate bearing block, a roller and a wear resistant layer, wherein the wear resistant layer is fixedly arranged on the surface of the roller; the baffle plate bearing block is fixed on the two ends of the roller; the central shaft is positioned in the center of the roller; the two ends of the central shaft are supported and fixed by the frame; internal wear resistant ceramic shaft sleeves are fixedly arranged on both sides of the central shaft; an external wear resistant ceramic shaft sleeve is fixedly arranged inside the baffle plate bearing block; the position of the internal wear resistant ceramic shaft sleeve corresponds to that of the external wear resistant ceramic shaft sleeve and the specification of the internal wear resistant ceramic shaft sleeve is matched with that of the external wear resistant ceramic shaft sleeve; and the internal wear resistant ceramic shaft sleeve and the external wear resistant ceramic shaft sleeve can rotate relative to each other.
Description
Technical field:
The utility model relates to a kind of ground roll.
Background technology:
Promote transportation and railway goods station specified conditions under the coal mine, necessary use car pusher and winch have been determined, guarantee its certain force of strain in order to prevent that wherein steel rope from mopping floor, need utilize ground roll that steel rope is supported and transmission, the quantity that ground roll uses is also many especially.Car pusher road steel rope ground roll generally is provided with one at 20m, and gug steel rope ground roll spacing is generally one of 10m.Present ground roll is made of frame, bearing, block plate bearing seat, cylinder, center shaft etc., and the cylinder two ends are fixed with the block plate bearing seat, and bearing is positioned at the block plate bearing seat, and center shaft penetrates in bearing, and the center shaft two ends are fixed by frame support.During work, inner center shaft and bearing cooperate realizes that block plate bearing seat and cylinder rotate.Because present bearing is the metal antifriction-bearing box, is arranged in harsh environment for a long time, weares and teares easily and gets rusty, thereby ground roll can not be rotated, directly, cause ground roll and steel rope abrasion very fast with the steel rope friction, change frequent, labor strength strengthens, influence problems such as production.
The utility model content:
The purpose of this utility model provides a kind of wear-resistant, withstanding corrosion, anti-hydrolysis, the ground roll that service life is long.
To achieve these goals, the utility model comprises: frame, center shaft, bearing gland, the block plate bearing seat, cylinder, wearing layer, cylinder surface is set with wearing layer, the cylinder two ends are fixed with the block plate bearing seat, center shaft is positioned at centre of the drum, the center shaft two ends are fixed by frame support, it is a wear-resistant ceramic axle sleeve in the center shaft both sides are set with, wear-resistant ceramic axle sleeve outside block plate bearing seat internal fixation is provided with, the mutual corresponding and specification in interior wear-resistant ceramic axle sleeve and outer wear-resistant ceramic axle sleeve position is mated mutually, can rotate mutually between interior wear-resistant ceramic axle sleeve and the outer wear-resistant ceramic axle sleeve.
Like this, because the rotation of ground roll realizes by rotating mutually between interior wear-resistant ceramic axle sleeve and the outer wear-resistant ceramic axle sleeve, very little between the two for slide rotation and friction drag, its distinctive wear-resistant, withstanding corrosion, hydrolytic resistance energy, be not afraid of dust intrusion and corrosion, can guarantee the ground roll reliability service, prolonged service life, reduce personnel labor, guaranteed normally carrying out of production.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a cross-sectional view of the present utility model.
The specific embodiment:
As shown in Figure 1, the utility model comprises: frame 1, center shaft 4, bearing gland 5, block plate bearing seat 7, cylinder 8, wearing layer 9.Cylinder 8 surfaces are set with wearing layer 9, cylinder 8 two ends are fixed with block plate bearing seat 7, center shaft 4 is positioned at centre of the drum, center shaft 4 two ends are by frame 1 support fixation, wear-resistant ceramic axle sleeve 3 in center shaft 4 both sides are set with, wear-resistant ceramic axle sleeve 6 outside block plate bearing seat 7 internal fixation are provided with, the mutual corresponding and specification in interior wear-resistant ceramic axle sleeve 3 and outer wear-resistant ceramic axle sleeve 6 positions is mated mutually, can rotate mutually between interior wear-resistant ceramic axle sleeve 3 and the outer wear-resistant ceramic axle sleeve 6.Interior wear-resistant ceramic axle sleeve can adopt Zirconium powder or alumina powder jointed, chromium oxide powder material with outer wear-resistant ceramic axle sleeve, compression moulding is the tubulose wear-resistant ceramic, through high temperature sintering,, make it be fixedly installed on the center shaft and block plate bearing seat inside by gluing embedding technique.In order to prevent that dust from entering gap between two axle sleeves, in two axle sleeve arranged outside axle sleeve gland 5 is arranged, utilize retainer ring 2 that the axle sleeve gland is fixed.The big I of specification of the present utility model is made series of products according to the equipment actual needs.
