Description

A kind of milling machine chain tensioning mechanism
Technical field
The present invention relates to a kind of milling machine chain tensioning mechanism, belong to field of road engineering machinery technical field.
Background technology
Milling machine is a kind of self-propelled road maintenance construction machinery for milling ground surface material, and large-scale milling machine is mainly used In municipal administration maintenance, pavement maintenance, small-sized milling machine is mainly used in the milling work in the places such as Roadway Construction, underground garage, parking lot Make.Small-sized milling machine is influenceed by structure space, and its kind of drive uses Chain conveyer mostly, and chain tensioning mechanism is mostly using peace Tensioning plate on support frame and the screw mandrel being fixed on tensioning plate carry out tensioning adjustment, but in use for some time It was found that, due to the sliding friction between tensioning plate and chain, the operating of chain is not only hindered, the serious mill of chain is also resulted in Damage, influence the use of strainer.
The content of the invention
In view of the shortcomings of the prior art, a kind of milling machine chain tensioning mechanism is now provided, it is ensured that between chain and sprocket wheel Back lash, makes chain operate steadily, and is conveniently adjusted strainer, improves service life of equipment.
To achieve the above object, this milling machine chain tensioning mechanism, including tensioning apparatus, support base, silk seat and adjustment silk Bar, it is characterised in that the tensioning apparatus is roller, the roller is arranged on support base by wheel shaft, and support base includes bottom Seat and depression bar, one end of the depression bar are hinged on the hinged seat of frame, and the other end and the base of depression bar are fixed, and silk seat is fixed on In frame, the bottom of adjustment screw mandrel is fixed on base, and the top of adjustment screw mandrel is provided with scale.
The advantage that tensioning plate is changed into roller is to make the sliding friction between chain and tensioning apparatus to be changed into rolling friction, Frictional force diminishes, therefore the operating of chain is more steady, and the abrasion of seen the bottom chain and tensioning apparatus, improves it and uses the longevity Life.Adjust strainer for convenience, in frame be provided with scale, adjust strainer when, only need to adjust screw mandrel adjust to Scale calibration position can ensure the reasonable back lash between chain and sprocket wheel, without frequently opening chain-wheel box, improve work Make efficiency.
Further, the adjustment screw mandrel includes hollow bolt and jackscrew, and the jackscrew is fixed on base, hollow bolt Interior to be provided with compression spring, the upper end of jackscrew is in contact with hollow bolt inner chamber with merging with compression spring.
Compression spring can be dynamically compensated the gap between chain and sprocket wheel between the jackscrew and hollow bolt, prevented Because the transmission failure that chain bounce is caused.
Further, the silk seat is fixed on hollow bolt by gland and clamp nut.During adjustment, only need to unclamp Then clamp nut, adjustment hollow bolt tightens clamp nut to calibration position.
Further, it is also associated with alignment pin between gland and silk seat.Can be when installing gland, silk seat by alignment pin Quick positioning, improves installation effectiveness.
The present invention is simple in construction, easy to adjust, improves the service life of chain traveling comfort and equipment.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of milling machine chain tensioning mechanism, including tensioning apparatus 1, support base 2, silk seat 3 and adjustment silk Bar 4, it is characterised in that the tensioning apparatus 1 is roller, the roller 1 is arranged on support base 2 by wheel shaft 1.1, support base 2 include base 2.1 and depression bar 2.2, and one end of the depression bar 2.2 is hinged on the hinged seat of frame, the other end of depression bar 2.2 with Base 2.1 is fixed, and silk seat 3 is fixed in frame, and the bottom of adjustment screw mandrel 4 is fixed on base 2.1, adjusts the top of screw mandrel 4 Provided with scale 5.
The advantage that tensioning plate is changed into roller is to make the sliding friction between chain and tensioning apparatus to be changed into rolling friction, Frictional force diminishes, therefore the operating of chain is more steady, and reduces the abrasion of chain and tensioning apparatus, improves it and uses the longevity Life.Adjust strainer for convenience, in frame be provided with scale, adjust strainer when, only need to adjust screw mandrel adjust to Scale calibration position can ensure the reasonable back lash between chain and sprocket wheel, without frequently opening chain-wheel box, improve work Make efficiency.
Further, the adjustment screw mandrel 4 includes hollow bolt 4.1 and jackscrew 4.2, and the jackscrew 4.2 is fixed on base On 2.1, compression spring 4.3 is provided with hollow bolt 4.1, upper end and the inner chamber of hollow bolt 4.1 of jackscrew 4.2, which are matched somebody with somebody, to be merged and compression Spring 4.2 is in contact.
Compression spring 4.3 can be to the gap dynamic between chain and sprocket wheel between the jackscrew 4.2 and hollow bolt 4.1 Compensation, prevents the transmission failure caused because chain is beated.
Further, the silk seat 3 is fixed on hollow bolt 4.1 by gland 6 and clamp nut 7.During adjustment, only Clamp nut 7 need to be unclamped, then adjustment hollow bolt tightens clamp nut to calibration position.
Further, it is also associated with alignment pin 8 between gland 6 and silk seat 3.Gland, silk can installed by alignment pin Quickly positioned during seat, improve installation effectiveness.
