Abstract

The utility model relates to a composite bearing used on a fork truck, which comprises an inner ring, an outer ring, a roller and a shaft head, wherein the roller is arranged between the inner ring and the outer ring; and the inner ring is in bolting connection with the shaft head. The composite bearing has the innovative characteristics that a slide block which can move in the axis direction of the shaft head is embedded at the left end part of the shaft head; a threaded hole penetrating the shaft head is formed at the right end part of the shaft head in a drilling manner; a set screw is matched with screw threads in the hole glidingly; and the end part of the set screw props against the inner side surface of the slide block. The composite bearing used on the fork truck has the advantages as follows: the slide fit can be carried out through the slide block instead of a traditional side roller, so that the stressed effect is good; components are reduced, and the structure is simplified; in addition, the set screw can push the slide block to move forwards so as to achieve the zero-clearance fit if a clearance exists between the slide block and a gantry during installation and use.

Description

A kind of fork truck combination bearing

Technical field

The utility model relates to a kind of combination bearing, particularly a kind of fork truck combination bearing.

Background technology

Traditional forklift door frame bearing is the side wheel bearing, promptly establish side wheel at the spindle nose end face of main bearing, this kind fork truck bearing assembly is more, complex structure, and potential faults is many, the cost height, stressed relatively poor, and the distance that can't regulate side wheel projecting shaft end surface, if being installed, the back side wheel can't be close to door frame, then need this bearing is reinstalled adjustment, scrap otherwise cause.

The utility model content

The technical problems to be solved in the utility model provides a kind of fork truck combination bearing, and simple in structure, fault rate is low, and the distance of scalable slide block projecting shaft end surface.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of fork truck combination bearing, comprise inner ring, outer ring, roller and spindle nose, be provided with roller between the inside and outside circle, bolt has spindle nose in the inner ring, and its innovative point is: described spindle nose left part is embedded with the slide block that can move along the axis direction of spindle nose, and described spindle nose right part is drilled with the tapped bore that runs through spindle nose, the hole negative thread is slidingly equipped with holding screw, and the slide block medial surface is withstood in the end of this holding screw.

Further, described slide block is the engineering plastics slide block, and its medial surface that contacts with tight fixed bolt is provided with sheetmetal.

Advantage of the present utility model is: replace traditional side wheel to carry out bearing fit by slide block, stressed effect is good, and has reduced assembly, simplify structure, and when installing and using,, can promote slide block reach realization no gap cooperation by dig-inning screw if having the gap between slide block and the door frame.Slide block is the high lightweight engineering plastics slide block of intensity, and its medial surface that contacts with tight fixed bolt is provided with sheetmetal, can avoid the slide block medial surface to be scratched, and has improved service life.

Description of drawings

Accompanying drawing is the utility model fork truck composite bearing structure scheme drawing.

The specific embodiment

As shown in drawings, comprise inner ring 1, outer ring 2, roller 3, spindle nose 4, slide block 5, holding screw 6, sheetmetal 7.

Clamp roll 3 between above-mentioned inner ring 1 and the outer ring 2, inner ring 1 has spindle nose 4 by screw 8 bolts, opens axial chute in the left side of spindle nose 4, the embedded slide block 5 that can move along axis direction of groove.This slide block 5 is the engineering plastics slide block, be drilled with the tapped bore that runs through spindle nose 4 in the right side of spindle nose 4, this tapped bore negative thread is equipped with holding screw 6, slide block 5 medial surfaces are withstood in the end of this holding screw 6, the medial surface that contacts with holding screw 6 at slide block 5 is provided with sheetmetal 7, can prevent that holding screw 6 from scratching the medial surface of slide block 5.

Claims

1. fork truck combination bearing, comprise inner ring, outer ring, roller and spindle nose, be provided with roller between the inside and outside circle, bolt has spindle nose in the inner ring, it is characterized in that: described spindle nose left part is embedded with the slide block that can move along the axis direction of spindle nose, described spindle nose right part is drilled with the tapped bore that runs through spindle nose, and the hole negative thread is slidingly equipped with holding screw, and the slide block medial surface is withstood in the end of this holding screw.

2. fork truck combination bearing according to claim 1 is characterized in that: described slide block is the engineering plastics slide block, and its medial surface that contacts with tight fixed bolt is provided with sheetmetal.
