Transmit steel band as a kind of kind of drive, application is more in the fields such as food industry equipment, semiconductor device be standby.With other kinds of drive, compare, transmit steel band and have the advantages such as low noise, high rigidity, relatively be applicable to clean occasion.As a kind of band kind of drive, the connection of steel band and roller needs necessary installation and firmly beforehand means.Conventional firmly beforehand means is to install the pretension roller additional in the steel band part of passing through, and by the position of fine setting pretension roller, adjusts the rate of tension of steel band, to realize the pretension to steel band.But the pretension roller that installs additional has often taken larger space, is not suitable for the occasion of less installing space.
Summary of the invention
For the technical problem that exists in above-mentioned prior art, the invention provides a kind of roller steel band pre-tightening apparatus, by being arranged on controlling device and the hold down gag in roller, realize adjusting and pretension to the steel band elasticity.Due within all controlling devices and hold down gag all be placed in roller, thus this compact design greatly saved and taken up room, can the narrow workplace of meeting spatial, this design simultaneously also has adjusting, characteristics easy to maintenance.
For achieving the above object, the technical solution adopted in the present invention is as follows:
A kind of roller steel band pre-tightening apparatus, be included in two steel bands that stagger, mutually do not interfere in space on vertical direction, and it is separate that two steel bands connect a cover function separately, do not produce controlling device and the hold down gag of interference; One of them steel band controlling device comprises locating stud, for locating stud lock screw and the steel band attachment screw of locking and positioning pin, hold down gag comprises compact heap and housing screw on compact heap under steel band, steel band; Another steel band controlling device comprises locating stud, for locating stud lock screw and the steel band attachment screw of locking and positioning pin, hold down gag comprises compact heap on compact heap under steel band, steel band, holddown plate, holddown plate set screw and housing screw; Two steel bands are connected on locating stud by the steel band attachment screw respectively, and are wound around in the opposite direction, realize thus the roller rotation; Under steel band on compact heap and steel band compact heap by the rotation of housing screw, remain on required compacted position respectively.
Under described steel band on compact heap and steel band compact heap with inclined-plane, compress.
Described locating stud inserts in the idler wheel bottom positioning pin hole.
Described locating stud has a word adjustment tank.
Described locating stud lock screw and housing screw are all exposed above roller and outer fix.
Technical solution of the present invention, by rotating the locating stud that can rotate freely, realization is to being connected in the adjusting of the steel band elasticity on locating stud, by compact heap on compact heap and steel band under the steel band that installs wedge shape in roller additional, upper compact heap and lower compact heap transverse shifting are realized the compression to steel band simultaneously; The maintenance of pretension position is realized by housing screw locking.Use the locating stud lock screw that locating stud is locked, to strengthen the pretension reliability.Unclamp locating stud lock screw and housing screw, adjust as required the steel band elasticity, last locking and positioning pin locked screw and housing screw.
The accompanying drawing explanation
Fig. 1 is roller overall structure schematic diagram of the present invention;
Fig. 2 is roller steel band structural drawing of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated: the present embodiment is implemented under take technical solution of the present invention as prerequisite, has provided detailed mode of execution, but protection scope of the present invention is not limited to following embodiment.
As depicted in figs. 1 and 2, steel band 1 is connected on different pins by attachment screw 7 and 13 from steel band 2, and is wound around in the opposite direction, realizes thus roller 3 rotations.Steel band 1 staggers with steel band 2 in the vertical direction spaces, does not mutually interfere.
During steel band 1 assembling, by steel band attachment screw 13, an end of steel band 2 is connected with locating stud 6.Locating stud 6 inserts in roller 3 bottom positioning pin holes, and the cooperation of its micro-gap namely can not exert an influence to positioning precision, is enough to again guarantee freely the turning round with certain surface friction drag of locating stud 6.Lower compact heap 9 and upper compact heap 5 compress with inclined-plane, and remain on needed compacted position by housing screw 4 fastening.The vertical plane of lower compact heap 9 is pressed in steel band 1 vertical plane of roller groove.
After the assembling, rotate locating stud 6 like this, just can adjust the elasticity of steel band 1.Then, locking housing screw 4, to be fixed on the pretension position by steel band 1.Finally, use locating stud lock screw 8 by locating stud 6 lockings, to strengthen the pretension reliability.
While safeguarding, unclamp locating stud lock screw 8 and housing screw 4, according to said sequence, adjust the steel band elasticity, last locking and positioning pin locked screw 8 and housing screw 4.Because a word adjustment tank, locating stud lock screw 8 and the housing screw 4 of locating stud all is positioned at roller top and the outside, so adjustment and maintenance is convenient, and operability is stronger.
During steel band 2 assembling, by steel band attachment screw 7, an end of steel band 1 is connected with locating stud 14.Locating stud 14 inserts in roller 3 bottom positioning pin holes, and the cooperation of its micro-gap namely can not exert an influence to positioning precision, is enough to again guarantee freely the turning round with certain surface friction drag of locating stud 14.Lower compact heap 10 and upper compact heap 11 compress with inclined-plane, and are subject to being threaded onto the constraint of the housing screw 16 of holddown plate 15 tapped holes, to remain on needed compacted position.The vertical plane of lower compact heap 10 is pressed in steel band 2 vertical plane of roller groove.
After the assembling, rotate locating stud 14 like this, just can adjust the elasticity of steel band 2.Then, locking housing screw 16, to be fixed on the pretension position by steel band 2.Finally, use locating stud lock screw 12 by locating stud 14 lockings, to strengthen the pretension reliability.
While safeguarding, unclamp locating stud lock screw 12 and housing screw 16, according to said sequence, adjust the steel band elasticity, last locking and positioning pin locked screw 12 and housing screw 16.Because a word adjustment tank, locating stud lock screw 12 and the housing screw 16 of locating stud all is positioned at roller top and the outside, so adjustment and maintenance is convenient, and operability is stronger.
These are only that specific embodiments of the invention are described.The present invention is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect protection scope of the present invention.
