Background
In the prior composite bearing, for example, patent CN200720129193.6 discloses a side clearance fine-adjustment device of a forklift bearing, which discloses a method for adjusting the axial clearance of a composite bearing through an adjusting bolt, wherein a shaft head is provided with a screw hole, and the adjusting bolt is in threaded fit with the screw hole and extends into the shaft head to jack a side roller support to achieve the purpose of adjusting the axial clearance of the side roller; however, with the arrangement, all the adjusting bolts are bound to bear the force of the side roller group, under the action of the force, the diameter of the adjusting bolt is bound to be large to ensure the contact area between the side roller bracket and the adjusting bolt, at least 8-10 threads of thread connection are required, the distance of the main roller extending out of the shaft head is also required to be long to ensure the stable connection between the adjusting bolt and the shaft head, and the tooth dropping is avoided; further, the composite bearing is used on the forklift, in order to ensure the gap between the outer portal and the inner portal, a hole must be formed in the inner portal to accommodate the shaft head which extends out too long, so that a scar hole is inevitably left when the shaft head and the inner portal are welded, and the composite bearing installed in the inner portal is inevitably unstable in up-and-down operation because the side roller inevitably passes through the scar hole in the up-and-down operation process of the composite bearing installed in the inner portal; further, a composite bearing for a forklift truck according to patent CN201210259096.4 has the same structure as described above.
Disclosure of Invention
In order to solve the problem, the utility model provides an axially adjustable combination bearing and fork truck portal thereof.
The technical scheme of the utility model:
an axially adjustable composite bearing comprises a main roller, a shaft head, side rollers and side roller supports, wherein the main roller is sleeved on the shaft head, a cylindrical hole is formed in one side end face of the shaft head, the side roller supports are arranged in the hole, and the side rollers are arranged on the side roller supports through side roller shafts; the side roller bracket is in sliding fit with the shaft head, moves along the axial direction of the hole, and is stacked and provided with a plurality of distance adjusting gaskets between the side roller bracket and the shaft head; an assembly hole is formed in the middle position of the bottom of the hole, and the diameter of the assembly hole is 6 mm; and the end surface of the other side of the shaft head extends out of the main roller by 6 mm.
By adopting the design of the gasket, the force borne by the side roller is directly transmitted to the shaft head, the extension length of the shaft head is not limited, and the end surface of the other side of the shaft head extends out of the main roller by 6 mm; the design has the pilot hole, when needs dismantle composite bearing, utilizes an ejector pin to pass the pilot hole, and top movable gasket and side gyro wheel support axial displacement can realize the partition of side gyro wheel and main gyro wheel, for increasing or reducing gasket quantity in order to adjust side gyro wheel axial position, provide convenience.
The side roller bracket is provided with a plurality of pin holes, a plurality of pin grooves are formed in the side roller bracket, positioning pins are arranged in the pin holes, the positioning pins are in clearance fit with the pin holes, and one end of each positioning pin penetrates through all distance-adjusting gaskets in sequence and extends into the pin grooves; by adopting the design, the punching processing is more convenient.
A forklift mast comprises an outer mast and an inner mast; a plurality of axially adjustable composite bearings are respectively arranged in the outer door frame and the inner door frame; the shaft head of the composite bearing installed in the outer gantry is welded with the inner gantry through the end face, and a small hole with the diameter of 6mm is formed in the inner gantry corresponding to the assembling hole in the inner gantry; the small hole is opposite to the assembling hole, and a centering hole is formed together for assisting in welding the shaft head and the inner door frame.
By adopting the design of the application, the end face of the other side of the spindle head extends out of the main roller by 6mm, a hole is not required to be formed on the inner gantry, the spindle head and the inner gantry are directly connected by welding through the end faces, and the formation of scar holes is avoided because the welding strength of the spindle head and the inner gantry is not affected by only 6mm assembling holes, so that the composite bearing installed in the inner gantry is ensured to run stably up and down; the inner gantry is provided with a small hole of 6mm, and the diameter of the small hole is small, so that the up-and-down operation of a composite bearing arranged in the inner gantry cannot be influenced; the design is that when the assembling hole is opposite to the small hole, namely the shaft head is positioned at the center of the inner portal frame, the positioning is convenient; and preferably, when welding spindle nose and interior portal, pass aperture and the pilot hole that corresponds with a stick of diameter 6mm in proper order, like this, on the one hand the location is accurate, misplaces when avoiding welding, and on the other hand plays certain auxiliary stay effect, and it is more laborsaving to weld, and it can to demolish the stick after the welding is accomplished.
The utility model discloses the advantage is, reasonable in design, simple structure, through the structure of improving compound bearing to avoid this problem of punching on the portal including need in the use, and then guarantee to install compound bearing in the portal and operate steadily from top to bottom.
