Abstract
The invention discloses a roller assembly, and relates to the technical field of the manufacture of a forklift truck. The roller assembly comprises an installation seat with a threaded through hole, wherein a roller seat is arranged in the installation seat, a roller is installed on the roller seat through a shaft on the roller in a penetrating manner, a jackscrew abuts the bottom surface of the roller seat by virtue of the threaded through hole of the installation seat, an anti-loosening jacking piece is arranged between the bottom surface of the roller seat and the jackscrew, a circular truncated cone which is concave downwards and is provided with a big top and a small bottom is arranged in the middle part of the top surface of the anti-loosening jacking piece, and a through hole corresponding to the shape of the circular truncated cone is formed in the middle part of the circular truncated cone. Compared with the prior art, the roller assembly is simple in structure and convenient to install; the anti-loosening jacking piece plays a role in elastic buffering and automatic adjustment, the roller can be prevented from being damaged by the instantaneous impact, and the normal operation of the entire mechanism can be guaranteed.
Description
Technical field
The present invention relates to fork truck manufacturing technology field, especially a kind of roller assembly for fork truck.
Background technique
Existing roller assembly, as shown in Figure 1, comprise the fitting seat 4 being provided with T-shaped through hole, jackscrew 3 is socketed with in the bottom of this fitting seat 4 through hole, the end face of this jackscrew 3, one of them side and bottom surface be stuck in be located at fitting seat 4 through hole in locking top flat 5 in, the top of locking top flat 5 is crimped with roller base 1 in the top of fitting seat 4 through hole, and this fitting seat 4 is built with roller 2, the end face of this locking top flat 5 is circular, and the end face of locking top flat 5 and the surface of contact of roller base 1 bottom surface are plane.There is following deficiency in the roller assembly of this structure: because the rigid contact surfaces of locking top flat and roller base is plane, locking top flat only plays locking effect to jackscrew, there is no elastic buffer function, when roller is subject to moment impact, locking top flat cannot carry out self-regulation to impact force, easily cause roller to damage, cause whole mechanism cisco unity malfunction.
Summary of the invention
The object of this invention is to provide a kind of roller assembly, it can solve existing fork truck roller assembly when being subject to moment impact, and locking top flat can not carry out self-regulation, and roller easily damages, thus causes the problem of whole mechanism cisco unity malfunction.
In order to solve the problem, the technical solution used in the present invention is: this roller assembly comprises the fitting seat being provided with tapped through hole, roller base is provided with in described fitting seat, roller is installed in described roller base by the axle on it, jackscrew is abutted with described roller base bottom surface by the tapped through hole of described fitting seat, locking top flat is provided with between described roller base bottom surface and described jackscrew, be provided with a up big and down small round platform recessed down in the middle part of the end face of described locking top flat, the middle part of this round platform is provided with the through hole corresponding with described truncated conical shape.
In the technological scheme of above-mentioned rollers assembly, technological scheme can also be more specifically: described via bottoms edge is h to the height of the end face lower end of described locking top flat, and described height h is less than or equal to the distance between described jackscrew end face and described roller base bottom surface.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
Owing to the end face of locking top flat of the present invention to be designed to there is middle part up big and down small round platform recessed down, and be provided with the through hole corresponding with this truncated conical shape at the middle part of round platform, the end face of locking top flat is made to have elastic buffer function, when roller is subject to moment impact, locking top flat end face produces elastic strain and apparatus with shock absorbing, serve fine buffer function, when impacting elimination, rely on the elastic recoil of this locking top flat end face round platform own, greatly reduce roller spoilage, the harmless operating time of the whole mechanism of effective prolongation, thus ensure the normal work of whole mechanism.

Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Embodiment 1:
As Fig. 1, the present invention shown in Fig. 2, comprise the fitting seat 104 being provided with tapped through hole, roller base 101 is provided with in fitting seat 104, roller 107 is installed in roller base 101 by the axle on it, jackscrew 103 is abutted with roller base 101 bottom surface by the tapped through hole of fitting seat 104, locking top flat 102 is provided with between roller base 101 bottom surface and jackscrew 103, a up big and down small round platform recessed down is provided with in the middle part of the end face of locking top flat 102, the through hole corresponding with this truncated conical shape is provided with at the middle part of round platform, this via bottoms edge is h to the height of the end face lower end of locking top flat 102, this height h is less than or equal to the distance between jackscrew 103 end face and roller base 101 bottom surface, during installation, roller 107 is arranged on after in roller base 101 and puts into fitting seat 104 top, then catch 106 is placed on roller 107, again by ring washer 105 to be threaded with fitting seat 104 by roller 107 and roller base 101 be fixed in fitting seat 104, locking top flat 102 is placed in the tapped through hole of fitting seat 104, then after being abutted against by the tapped through hole screw-in fitting seat 104 of the fitting seat 104 and end face round platform bottom surface of locking top flat 102 by jackscrew 103, the elongate strip that the outside of locking top flat 102 end face links being exposed outer partly bending of fitting seat 104 is placed in jackscrew 103 bottom recesses, because locking top flat 102 end face round platform has elastic buffer effect, have position-limiting action to jackscrew 103, the springing stroke height of locking top flat 102 is corresponding to the height h of the end face lower end of locking top flat 102 with the bottom margin of this round platform middle through-hole simultaneously, when roller is subject to moment impact, elastic strain is produced and apparatus with shock absorbing by the round platform of locking top flat 102 end face, serve good buffer function, when impacting elimination, rely on the elastic recoil of round platform of locking top flat 102 end face own, greatly reduce roller spoilage, effectively extend the harmless operating time of whole mechanism, thus ensure normally working of whole mechanism, locking top flat 102 in the present embodiment is made up of metallic material.
Embodiment 2:
As shown in Figure 4, roller assembly in the present embodiment is compared with the roller assembly in embodiment 1, its difference is: be provided with the boss 108 matched with the through hole of the round platform of locking top flat 102 at the top end of jackscrew 103, the height of this boss 108 and the height h corresponding setting of the middle through-hole bottom margin of the end face round platform of locking top flat 102 to locking top flat 102 end face lower end, when the round platform elastic force of locking top flat 102 end face weakens or lost efficacy, boss 108 can directly contact with roller base 101 bottom surface, serve the position-limiting action to jackscrew 103 and buffer function, roller 107 can be avoided better to damage by moment impact, guarantee normally working of whole mechanism.
