Description

A kind of novel combination roller

Technical field:

The utility model relates to the door frame or the pallet fork roller technical field of haulage equipment, a kind of novel combination roller.

Background technology:

The present roller that is used for door frame or pallet fork on mechanical equipments such as storage haulage equipment such as electronic piler, plug in car has produced the gap owing to being worn in continuous use and can't adjust; Behind interior outer mast suit, also can produce a backlash, it has had a strong impact on the kinematic accuracy of door frame or pallet fork and the stability of car load, usually the way that solves has only the accuracy of manufacture that improves interior outer mast, reduce this backlash, but so just increased the manufacture difficulty and the cost of door frame.Recently a kind of roller also occurring will sidewinder wheel shaft and make eccentric shaft, make the side wheel parallel motion by adjusting offset, to reduce backlash, but it is differential that the shortcoming of this roller is that its adjustment amount has, adjustment that the more important thing is it is to operate from the inboard, can't adjust in assembling back and the use, this has just limited its application.

The utility model content:

The purpose of this utility model provides a kind of novel combination roller, can adjust backlash at any time, to improve door frame or the kinematic accuracy of pallet fork and the stability of car load, reduces production costs.

The technical solution of the utility model is: a kind of novel combination roller comprises main roller, side wheel and main roller inner ring, main roller inner ring one end of adorning in main roller is equipped with baffle ring, in main roller inner ring and baffle ring, spindle nose is installed, be provided with circlip groove at spindle nose one end, back-up ring is housed in circlip groove, spindle nose is provided with boss, in spindle nose other end screw, trimming screw is housed, trimming screw one termination is provided with inner hexagonal hole, is equipped with in spindle nose and sidewinders wheel seat, and trimming screw presses closer and sidewinders wheel seat.

Sidewinder side wheel is housed in the wheel seat, needle roller is housed in the side wheel, seal ring respectively is housed in the groove that establish at the side wheel two ends, side wheel, needle roller, seal ring all are enclosed within on the tubular axis, straight pin is housed in the tubular axis, two ends of tubular axis and straight pin are packed into and are sidewindered in two circular holes on the wheel seat circumference, and two ends of straight pin are also packed in two long flat holes on the spindle nose circumference simultaneously.

Described a kind of novel combination roller, the main roller outer ring of this combination roller are interior hard outer soft special material.

The utility model internally backlash of outer mast carries out the stepless difference adjustment, and is from outside operation, no matter be before and after assembling, still in use all can implement to adjust operation, remains at an optimum regime with the value of guaranteeing backlash.So not only improved the kinematic accuracy and the stability of machine, thereby made the quality of product promote a class, but also the manufacture difficulty of outer mast in this machine is reduced greatly.So the utility model can make corresponding engineering goods reach the effect that promotes quality, reduces production costs.

Specific embodiments:

Referring to Fig. 1, Fig. 2, Fig. 3, in the main roller 4 of the present utility model main roller inner ring 6 is installed,

Several rollers 5 are housed between main roller 4 and the main roller inner ring 6, at main roller inner ring 6 one ends baffle ring 7 is housed, in main roller inner ring 6 and baffle ring 7, spindle nose 2 is installed, be provided with circlip groove at spindle nose 2 one ends, back-up ring 8 is housed in circlip groove, boss of establishing on the spindle nose 2 and back-up ring 8 are with baffle ring 7, main roller inner ring 6 all clamps in case anti-avulsion falls, in spindle nose 2 other end screws, trimming screw 1 is housed, trimming screw 1 one terminations are provided with inner hexagonal hole, in spindle nose 2, be equipped with and sidewinder wheel seat 3, trimming screw 1 presses closer and sidewinders wheel seat 3, sidewinder side wheel 9 is housed in the wheel seat 3, needle roller 10 is housed in the side wheel 9, in the groove that establish at side wheel 9 two ends seal ring 11 is housed respectively, side wheel 9, needle roller 10, seal ring 11 all is enclosed within on the tubular axis 12, and straight pin 13 is housed in the tubular axis 12, tubular axis 12 and two ends of straight pin 13 are packed into and are sidewindered in two circular holes on wheel seat 3 circumference, and two ends of straight pin 13 are also packed in two long flat holes on spindle nose 2 circumference simultaneously.

The M place of indication is installation site of the present utility model among Fig. 4, Fig. 5 is that the N of Fig. 4 is to the half-twist view, when the utility model is installed between the interior

outer mast

14,15, generally being paired symmetry places, spindle nose 2 of the present utility model and outer mast 14 weld togethers, another spindle nose 2 and pallet fork 16 weld togethers.

Referring to Fig. 6, on outer mast 14 installations position of the present utility model, be drilled with mounting hole, an end that spindle nose 2 is equipped with trimming screw 1 inserts in the mounting hole, again with spindle nose 2 and outer mast 14 weld togethers; When interior

outer mast

14,15 suits can produce a backlash X later, it has had a strong impact on the kinematic accuracy of door frame or pallet fork and the stability of car load, therefore the utility model installs when adjusting, inner-hexagon spanner is inserted right-hand revolution (it is locking to be coated with a little screw thread glue at trimming screw 1 outside face in advance) in the inner hexagonal hole of trimming screw 1, trimming screw 1 promotes to sidewinder wheel seat 3 and moves right, sidewinder wheel seat 3 and drive side wheels 9 move right together (seeing the long and two-short dash line place), thereby adjust the backlash X between outer mast 14 and the inner upright mounting 15, guarantee the normal operation of side wheel 9.Same principle, when spindle nose 2 is welded on the position of pallet fork 16, inner-hexagon spanner is inserted right-hand revolution in the inner hexagonal hole of trimming screw 1, trimming screw 1 promotes to sidewinder wheel seat 3 and moves, thereby adjust the backlash X between pallet fork 16 and the inner upright mounting 15, guarantee the normal operation of side wheel 9.If backlash is too small, cause resistance of motion excessive, inner-hexagon spanner need only be inserted anti-clockwise rotation in the inner hexagonal hole of trimming screw 1, promptly be adjustable to suitable backlash position.

When pallet fork 16 upwards rises, constantly upwards rise along inner upright mounting 15 by the combination roller, when reaching certain position, drive inner upright mounting 15 again and continue to rise, the opposite side of inner upright mounting 15 is risen, until reaching desired height along outer mast 14 by the combination roller.

Special material and manufacturing process are adopted in main roller 4 outer rings, make in this part hard outer soft, only can wear and tear own during work and the door frame that can not wear and tear, work and to change main roller 4 outer rings after certain time limit, just can keep the good order and condition of machine again, thereby the durability of machine is improved to greatest extent.
