Description
Technical field
The present invention relates to the claw chain tensioning mechanism of a kind of chain drive technical field, particularly harrow for paving device.
Background technique
The chain drive of harrow for paving device generally comprises drive motor at present, the main chain wheel driving mechanism reaches the claw chain aggregate motion that is driven by the main chain wheel driving mechanism, and the combination of claw chain is divided into two groups usually, respectively be arranged on the both sides of claw device frame, the claw motion that claw chain in driving two ends synchronously and the claw chain making up is connected realizes the rake material.Because the claw chain is a reel chain, loose chain phenomenon inevitably appears in running.Therefore often the claw chain need be carried out tensioning.Existing chain tensioning mechanism exists the problem of inconvenient operation, structure more complicated.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of claw chain tensioning mechanism of harrow for paving device, to solve the existing existing problem of chain tensioning mechanism.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
The claw chain tensioning mechanism of harrow for paving device, it is characterized in that, comprise tension sprocket, chain tensioner spindle, rolling bearing units, go up slide rail, glidepath, upper end base, lower end seat, tensioning screw, butterfly spring, L shaped bearing, guide pin bushing and related nut, described upper and lower end seat is installed on the frame of harrow for paving device; Described upper and lower slide rail is installed in respectively on the described upper and lower end seat, and described rolling bearing units are installed on the chain tensioner spindle, and described rolling bearing units are provided with the upper and lower chute that is actively tied in described upper and lower slide rail; Described L shaped bearing is fixed on the frame of harrow for paving device; Described tensioning screw one end is connected with described rolling bearing units, passes the axis hole on the described L shaped bearing behind tensioning screw the other end cover upper guide bush, the butterfly spring; Be positioned at described tensioning screw and be rotary with the adjusting nut of regulating pretightening force of butterfly spring on the thread section of guide pin bushing and this section of rolling bearing units, on described tensioning screw is positioned at the thread section of this section guide pin bushing outside, be rotary with the stop nut of qualification guide pin bushing mobile position; Described tension sprocket is installed on the described chain tensioner spindle.
In order to realize the aligning of chain tensioner spindle and tension sprocket, the present invention is separately installed with upper and lower pressing plate at described upper end base, lower end seat, is rotary with the aligning bolt on described upper and lower pressing plate, is rotary with fastening screw nut on the aligning bolt.
In order accurately to show tension sprocket and chain tensioner spindle tension position, on the slide rail scale is installed on described.
Regulating method of the present invention is: when the claw chain relaxation, regulate the adjusting nut on the tensioning screw, make it to L shaped bearing direction motion, by guide pin bushing butterfly spring is compressed, simultaneously also regulate stop nut, make it, after butterfly spring discharges towards moving away from L shaped bearing direction, to promote tension sprocket to away from L shaped support movement by guide pin bushing and adjusting nut, tensioning screw, thereby play the purpose of tensioning claw chain.Butterfly spring can keep the claw chain to be in tensioning state.If after butterfly spring discharges fully, when the claw chain still is in relaxed state, can regulates butterfly spring according to the method described above and carry out accumulation of energy.
Owing to adopted as above design proposal, the present invention can regulate the rate of tension of claw chain easily at any time, and has easy to operate, advantage of simple structure.After this claw chain tensioning mechanism carried out an accumulation of energy to butterfly spring, energy auto-tensioning after chain takes place to become flexible was until needs accumulation of energy next time.
Description of drawings
Fig. 1 is the structural representation of the claw chain tensioning mechanism of harrow for paving device of the present invention.
Fig. 2 is that the K of Fig. 1 is to view.
Embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, the claw chain tensioning mechanism of harrow for paving device, comprise tension sprocket 1, chain tensioner spindle 2, rolling bearing units 3, go up slide rail 4, glidepath 5, upper end base 6, lower end seat 7, tensioning screw 8, butterfly spring 9, L shaped bearing 10, guide pin bushing 11, tension sprocket 1 is last sprocket wheel in the whole claw chain chain wheel set, and chain tensioner spindle 2 is last root sprocket shaft in the claw chain chain wheel set.
Offer square hole 13 on the frame 12 of harrow for paving device, chain tensioner spindle 2 passes from this square hole 13, and the purpose of offering square hole 13 is to be convenient to chain tensioner spindle 2 adjust.
Rolling bearing units 3 are installed on the axle head of chain tensioner spindle 2, its upper and lower position offers upper and lower chute 17,18, one side has in order to the hole that square nut 19 is installed and holds the screw hole that tensioning screw 8 passes, after tensioning screw 8 passes this screw hole, screw on square nut 19 and fastening screw nut 20, after throwing fixing pin 21 between square nut 19 and the tensioning screw 8, tensioning screw 8 firmly is connected with rolling bearing units 3.
In order to regulate chain tensioner spindle 2 and tension sprocket 1 is concentric with other sprocket wheel, on upper end base 6 and lower end seat 7, be separately installed with upper and lower pressing plate 22,23 by bolt, on upper and lower pressing plate 22,23, be rotary with aligning bolt 24, be rotary with fastening screw nut 25 on the aligning bolt 24.Unclamp fastening screw nut 25, regulate the aligning bolt 24 on the upper and lower pressing plate 22,23, aligning bolt 24 promotes to go up slide rail 4 or glidepath 5 moves, and can implement the aligning of chain tensioner spindle 2 and tension sprocket 1 and the adjusting of guiding clearance.Screwing fastening screw nut 25 after regulating gets final product.
In order to show the tension position of tension sprocket 1 and chain tensioner spindle 2 exactly, on last slide rail 4, scale 26 is installed.
