Abstract
The invention discloses a friction transmission mechanism for a power and free conveyer. The friction transmission mechanism is characterized in that a step shaft is fixedly arranged in a shaft hole of a base of a trolley through an inner-side shaft end of the step shaft; an outer-side shaft end of the step shaft is set as a threaded section; a first friction plate, a chain wheel, a second friction plate, a first spring baffle plate, a spring, a second spring baffle plate and a locknut are sheathed the step shaft from one side of the steo shaft, where the base of the trolley is arranged, to the outer-side shaft end of the step, the locknuts locks the first friction plate and the second friction plate by the spring to be set in a maximum static friction state; and due to a chain transmission mechanism formed by driving chain wheels, driven chain wheels and chains, which drive continuously, the chain wheels and the chains are meshed with each other. The friction transmission mechanism is long in service life, abrasion-resistant and low in noise, and can bear large-scale plates.
Description
Technical field
The present invention relates to a kind of slip gear, saying so more specifically is applied in a kind of transmission device that drives the motion of plate transport trolley on the plate conveyer of weld car workshop.
Background technology
At the robot work station of weld car line, because the artificial part difficulty that goes up perhaps in the dangerous property of last part regional work, need be used collecting and sending conveyer.The collecting and sending conveyer upper plate transport trolley driver train that uses at present generally be utilize chain and the dolly that needs to drive between the transmission of static friction force direct friction; Behind the position that dolly arrival needs; Dolly be locked mechanism locking, stop; And the chain persistent movement, slide relative between dolly and the chain.This mode is because of after being locked, stopping at dolly; Have cliding friction between dolly and the chain, significantly reduced the service life of chain, the component life that rubs mutually with chain on the dolly simultaneously is shortening greatly also; So different, can produce very big noise between the metal in the cliding friction process.Because the gravity of dolly acts on the chain fully, limit the weight that to carry plate on the dolly on the other hand, can't be used for the transportation large-scale plate.
Summary of the invention
The present invention is the weak point of avoiding above-mentioned prior art to exist, provides a kind of time in service life long, wear-resistant, and noise collecting and sending conveyer very little, that can carry large-scale plate is used slip gear.
Technical solution problem of the present invention adopts following technical scheme:
Collecting and sending conveyer of the present invention is to be provided with the constructional feature of slip gear:
One step axle is fixedly installed in the axis hole of dolly pedestal with inboard axle head; The outside axle head of said step axle is set to thread segment; Axle head is set with first friction lining, sprocket wheel, second friction lining, first spring stop piece, spring, second spring stop piece and jam nut to a side on said step axle, from dolly pedestal place successively towards the outside of step axle, is the maximum static friction force state of setting through spring with first friction lining and the locking of second friction lining with said jam nut;
By the drive sprocket of continuous transmission, constituted continuous chain connecting gear by movable sprocket and chain, said sprocket wheel and chain are meshing with each other.
Collecting and sending conveyer of the present invention also is with the constructional feature of slip gear:
The axle stop motion mechnism of step axle is set, and is to fixedly install a locked spacer in the outside of dolly pedestal through screw, and said axle locked spacer is inlaid in the rotation of locking groove interior prevention step axle in dolly pedestal axis hole of said step axle.
Said first spring stop piece and the second spring stop piece spline are arranged on the step axle.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, the present invention is between the dolly pedestal and first friction lining; Between first friction lining and the sprocket wheel; And formation friction between the sprocket wheel and second friction lining; Selecting first friction lining and second friction lining is oil-containing nylon or graphite copper-based material, make can prolong greatly its service life, wear-resistant, noise is very little.
2, the gravity of dolly does not drop on the chain among the present invention, and this makes the weight that can carry plate increase greatly, is particularly suited for the transportation large-scale plate.
3, medium chain connecting gear of the present invention is not worn itself, can improve complete machine service life thus greatly, reduces use cost.

Fig. 2 is load mode scheme drawing among the present invention;
Label among the figure: 1 substrate; 2 first friction linings; 3 sprocket wheels; 4 springs; 5a first spring stop piece; 5b second spring stop piece; 6 nuts; 7 step axles; 8 second friction linings; 9 locked spacers; 10 screws; 11 main drive sprockets; 12 by movable sprocket; 13 chains.
The specific embodiment
Collecting and sending conveyer is to be provided with slip gear in the present embodiment:
Shown in Figure 1, a step axle 7 is fixedly installed in the axis hole of dolly pedestal 1 with inboard axle head; The outside axle head of step axle 7 is set to thread segment; On step axle 7, axle head is set with first friction lining 2, sprocket wheel 3, second friction lining 8, the first spring stop piece 5a, spring 4, the second spring stop piece 5b and jam nut 6 successively towards the outside of step axle 7 from the side at dolly pedestal 1 place, first friction lining 2 being locked with second friction lining 3 through spring 4 with jam nut 6 is the maximum static friction force state of setting;
Shown in Figure 2, by the drive sprocket 11 of continuous transmission, constituted continuous chain connecting gear by movable sprocket 12 and chain 13, sprocket wheel 3 is meshing with each other with chain 13.
As shown in Figure 1; The axle stop motion mechnism of step axle 7 is set in the present embodiment; Be to fixedly install a locked spacer 9 in the outside of dolly pedestal 1 through screw 10, axle locked spacer 9 is inlaid in the locking groove of step axle 7, to stop the rotation of step axle 7 in dolly pedestal axis hole; The first spring stop piece 5a and the second spring stop piece 5b spline are arranged on the step axle 7.
First friction lining 2 and second friction lining 8 are selected the oil-containing nylon material for use, or select oil-containing graphite copper-based material for use, and its friction coefficient is little, resistance to abrasion good, wearing and tearing are little, and under identical service conditions, noise also reduces greatly.
In the practical implementation, dolly is set,, track adjusting wheel is installed on the dolly as the load carrier of workpiece at the sidepiece of slip gear, can be along guide rail movement; Slip gear is fixedly mounted on the dolly through dolly substrate 1, as the dolly driver train.
Sprocket wheel 3 does not rotate around step axle 7 under the static friction force effect of first friction lining 2 and second friction lining 8, thereby whole slip gear drives dolly and chain 13 synchronous A points from Fig. 2 move to B point place; When dolly is moved ahead by the catch gear prevention of side setting; Dolly and slip gear can't move forward; This moment, chain 13 still remained transmission, and the friction force between sprocket wheel 3 and first friction lining 2, second friction lining 8 relatively rotates between sprocket wheel 3 and first friction lining 2 and second friction lining 8 above maximum static friction force; Sprocket wheel 3 is around 7 idle running of step axle, and dolly does not advance.
Through on step axle 7, turning the amount of compression that nut 6 can be adjusted spring 4; Thereby adjust the pressure between first friction lining 2, sprocket wheel 3 and second friction lining 8, finally play the effect of maximum static friction force between adjustment sprocket wheel 3 and first friction lining 2 and second friction lining 8.According to the weight of actual fed plate and speed adjustment sprocket wheel 3 and first friction lining 2,8 maximum static friction forces of second friction lining, to obtain making system's running steadily, the effect of wearing and tearing minimum.
