Abstract
The utility model relates to a chain wheel tensioning device which comprises a tensioning bracket and a tensioning chain wheel which is arranged on the tensioning bracket in a turning mode. The axis of the tensioning chain wheel is vertical arranged. The tensioning bracket comprises a dynamic bracket and a static bracket for fixed arrangement. The tensioning chain wheel is assembled on the dynamic bracket. A fixed vertical plate is arranged on the static bracket. A moving vertical plate which is parallel to the fixed vertical plate and is opposite to the fixed vertical plate is fixedly arranged on the dynamic bracket. One end of an adjusting threaded rod is arranged on the fixed vertical plate in a rotating mode, and the other end of the adjusting threaded rod penetrates through the moving vertical plate in a sliding mode, and a compressed spring is arranged through the adjusting threaded rod. One end of the compressed spring is pressed toward the moving vertical plate, and other end of the compressed spring is pressed upward the fixed vertical plate or the baffle which is sleeved on the middle portion of the adjusting threaded rod, the axial position of the baffle is adjusted and stopped and limited by an adjusting nut, and the tensioning chain wheel is automatically tensioned by the elastic force of the compressed spring.
Description
Technical field
The utility model relates to a kind of sprocket tension device.
Background technique
Chain transmission is a kind of common power transmission mode, can cause chain pitch to strengthen after working long hours, and makes chain slack list sag increasing, reduces chain and sprocket wheel and effectively meshes, and transmission capacity is descended.Traditional sprocket tensioning structure is with bolt, sprocket wheel to be fixed on the purpose that reaches tensioning on support after artificial tensioning.This tension structure inconvenient operation in use needs the position tension chain by continuous adjustment sprocket wheel, and is also easily loosening when carrying out tensioning, causes beating of chain, affects the performance of machine.
Summary of the invention
The purpose of this utility model is to provide a kind of sprocket tension device that can realize voluntarily tensioning after chain is lax.
in order to realize above purpose, the technological scheme that the utility model adopts is: sprocket tension device, comprise tensioning support and the tension sprocket that is rotatably installed on the tensioning support, the axis of tension sprocket vertically arranges, the quiet support that described tensioning support comprises moving support and is used for being fixedly installed, tension sprocket is assemblied on moving support, has fixed board on quiet support, be installed with parallel with fixed board on moving support, the mobile riser that is oppositely arranged, one end spinning of one adjusting screw rod is on fixed board, the other end slides through mobile riser, be coated with stage clip on adjusting screw rod, one end of stage clip pushes up and is pressed on mobile riser, the other end top is pressed on fixed board or the top is pressed on the baffle plate that is sheathed on the adjusting screw rod middle part, this baffle plate is spacing to its axial position adjustment and block by adjusting nut, tension sprocket is realized tensioning voluntarily under the promotion of stage clip elastic force.
Have fixing substrate vertical with fixed board on described quiet support, have fixing slide plate vertical with mobile riser on described moving support, slide plate is assemblied on substrate along the axial direction guiding movement of adjusting screw rod, and described tension sprocket is assemblied on slide plate.
Screwed guide spiro rod on described slide plate, substrate is provided with the slotted hole that extends along the adjusting screw rod axial direction, is arranged with the guide sleeve that is slidably matched with slotted hole sidewall guiding on guide spiro rod.
The end of an end that is positioned at mobile riser of described adjusting screw rod is provided with the stopper that prevents that mobile riser from deviating from from adjusting screw rod.
The utility model is when installing and using, stage clip applies pretightening force by chain to it and carries out precompression, when chain causes chain length to lengthen due to wearing and tearing or other reasons, realize tensioning voluntarily thereby the moving support drive of stage clip release portion pretightening force promotion tension sprocket moves, guaranteed the normal operation of machine.
The utility model is provided with stopper at adjusting screw rod one end, has prevented that effectively mobile riser from deviating from from adjusting screw rod.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation;
Fig. 2 is the worm's eye view of Fig. 1.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
sprocket tension device as shown in Figure 1, 2, comprise tensioning support 2 and the tension sprocket 1 that is rotatably installed on the tensioning support, the axis of tension sprocket 1 vertically arranges, the quiet support 4 that described tensioning support 2 comprises moving support 3 and is used for being fixedly installed, have fixed board 5 and fixing substrate 6 vertical with fixed board 5 on quiet support 4, be installed with mobile riser 7 and fixing slide plate 8 vertical with mobile riser 7 parallel with fixed board, that be oppositely arranged on moving support 3, tension sprocket 1 is assemblied on moving support 3 by slide plate 8, one end spinning of adjusting screw rod 9 is on fixed board 5, the both sides of fixed board 5 are provided with the locking nut of secured adjusted screw rod 9, adjusting screw rod 9 the other ends slide through mobile riser 7, and be provided with the stopper 10 that prevents that mobile 7 risers from deviating from from adjusting screw rod 9 in this end, be coated with stage clip 11 on adjusting screw rod 9, one end of stage clip 11 pushes up and is pressed on mobile riser 7, the other end top is pressed on the baffle plate that is sheathed on adjusting screw rod 9 middle parts, this baffle plate by adjusting nut to its axial position adjust and block spacing, the opposite side of adjusting nut is provided with locking nut, tension sprocket 1 is realized tensioning voluntarily under the promotion of stage clip elastic force.Screwed guide spiro rod 12 on described slide plate 8, substrate 6 is provided with the slotted hole 13 that extends along adjusting screw rod 9 axial directions, be arranged with the guide sleeve 14 that is slidably matched with slotted hole 13 sidewall guiding on guide spiro rod 12, slide plate 8 is assemblied on substrate 6 along the axial direction guiding movement of adjusting screw rod 9.
During use, chain is hung on tension sprocket, then by regulating the position of adjusting nut, the compressive force of regulating stage clip is slided thereby promote tensioning supporting band movable sprocket, makes chain tensioning voluntarily.
In other embodiments of the present utility model, moving support can not coordinate with quiet support guiding movement, and this moment, substrate and slide plate did not need to arrange, and fixed board can directly be connected with corresponding equipment when mounted.In addition, the structure of dynamic and static support is not limited to the said structure form, as long as on two stands, correspondence is provided with fixed board and mobile riser.
In other embodiments of the present utility model, in the situation that adjusting screw rod stretches out mobile riser sufficient length, the stopper on adjusting screw rod can not arrange.
In other embodiments of the present utility model, stage clip can immediate roof be pressed on fixed board.
