Description
Technical field
A kind of automatic takeup is the utility model is related to, is used for more particularly, to a kind of to the transmission on rubber-tyred roller
Chain carries out the mechanism of auto-tensioning, belongs to field of road engineering machinery field.
Background technology
At present, rubber-tyred roller is pressed because it has good flexible compaction capacity and will not destroyed in compacting process
Real aggregate, therefore become compacting class mechanical engineering equipment essential in asphalt pavement construction, it is usually used in asphalt road
Face pressure reality and the compacting of stabilized soil road base；
The common drive form of domestic rubber-tyred roller is mainly rear wheel drive, and drive axle drives trailing wheel by driving chain
Driven sprocket is driven, and Chain conveyer manufacture and installation accuracy require relatively low, and bearing capacity is larger, there is certain buffering and damping
Performance, transmission efficiency is higher, therefore is widely used at home；But after chain drive for a period of time, chain can occur
Abrasion elongation, although relatively slower, extended with the abrasion of chain, cause slack list sag excessive, caused and engage bad and chain
Bar is vibrated and the generation of tooth is jumped in transmission, therefore just needs to be tensioned driving chain；
Because rubber-tyred roller is during compacting operation and transition, forward-reverse action has, and its drive sprocket has
Rotate and reverse, when rubber-tyred roller advances, drive sprocket rotates forward, and driving chain one end is slack list, and the other end is pilled-in selvedge, when
When rubber-tyred roller retreats, then slack list and pilled-in selvedge are exchanged, therefore are considered as need to using during tensioning wheel tensioning driving chain two-way
Tensioning；
Nowadays the rubber-tyred roller chain tensioning mechanism of domestic each producer mainly by the way of centre-to-centre spacing is adjusted, raises drive
Movable sprocket, so that chain tension, its design structure is substantially as shown in Figure 3：By the closely-pitched screw rod at centre of sprocket line both ends
101st, bridge seat 102 and hold-down bolt 103 is driven to form；
Above-mentioned adjustment mode realizes that the process of the tensioning of chain is comparatively laborious, drives between bridge seat 102 and closely-pitched screw rod 101
It is smaller to be threadedly coupled gap, need to first adjust one end closely-pitched screw rod 101, and the distance of very little can only be adjusted, then adjusts other one
End, otherwise occurs thread biting locking phenomenon, it is therefore desirable to which the continuous small distance of repetition adjusts left and right closely-pitched screw rod 101 respectively makes drive
The dynamic lifting of bridge seat 102；After both ends closely-pitched screw rod 101 is adjusted to correct position, four hold-down bolts 103 are tightened；Due to
Rubber-tyred roller is compact-sized, and vehicle frame is totally enclosed type unitized frame, and the instrument of closely-pitched screw rod 101 in inner side is relatively inaccessible to grasp
Make position, adjustment could be realized after water tank and other associate members need to be dismantled；The bottom locating surface of closely-pitched screw rod 101 and frame contact,
Due to the frictional force of drive axle own wt increase contact surface, cause to adjust the larger moment of torsion of closely-pitched screw rod needs, adjusted in building site
It is whole to employ larger air pressure gun and be adjusted, and once tensioning need to adjust four closely-pitched screw rods 101；Therefore adjustment chain quantities
Greatly, adjustment is difficult.
The content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided one kind is simple in construction, easy to maintenance and can carry out double
To the rubber-tyred roller driving-chain automatic takeup of tensioning.
What the purpose of this utility model was realized in：
A kind of rubber-tyred roller driving-chain automatic takeup, described device include two companies being symmetrical set

Chain is in contact with tensioning wheel assembly.
A kind of rubber-tyred roller driving-chain automatic takeup of the utility model, the tensioning wheel assembly include axle, axle
It is installed on connecting rod, bearing is set with the axle, wearable bearing base is set with the bearing；Wearable bearing base is pressed together on biography
On the lateral surface of dynamic chain, the tension spring is connected between the axle of two groups of tensioning wheel assemblies.
A kind of rubber-tyred roller driving-chain automatic takeup of the utility model, axle sleeve, the axle are set with the axle
End face on pressing have bearing gland, and bearing is between bearing gland and axle sleeve；Also pressing has end on the end face of the axle
Lid, bolt are spun on axle after passing through end cap and bearing gland；Sealing ring is provided between end cap and bearing gland.
A kind of rubber-tyred roller driving-chain automatically tensioning method of the utility model, when driving chain works, driving chain
Lateral surface is fitted on the circumferential surface of the wearable bearing base of tensioning wheel assembly, pulling force of two tensioning wheel assemblies in tension spring
Under effect, apply the pulling force of formed objects to driving chain both sides, and rolled in driving chain transmission process with wearable bearing base
Contact.
Compared with prior art, the beneficial effects of the utility model are：
This patent provides tension force using tension spring and causes the wearable bearing base of driving chain and tensioning wheel assembly rolls to connect
Touch, and the consistent of driving chain both ends tensile force ensure that by tension spring, without artificial regulation so that it has automatic adjust
Whole function.
