Description
Technical field
The utility model relates to a kind of chain tensioning device, particularly relates to the device that a kind of wheelbase do not changed between driving wheel and follower can realize chain tensioner.
Background technique
Chain transmission is widely used as a kind of common power delivery mode, the tensioner of chain must be related in its embody rule, present most tensioner mode is all that the wheelbase by changing two sprocket wheels (i.e. driving wheel and follower) realizes, because structure limit, the mode changing wheelbase is not necessarily suitable for some occasion.For the application that wheelbase is less, also have and carry out adjusting chain tensioner degree by increasing expansion tightening wheel, but traditional expansion tightening wheel complex structure, is also difficult to be suitable for for comparatively reel chain.
Model utility content
The purpose of this utility model is just to provide a kind of chain tensioning device realizing chain tensioner by increasing expansion tightening wheel to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of chain tensioning device, be installed on support, described support is provided with driving wheel by live axle, chain is around on described driving wheel, described chain tensioning device comprises tension bolt, tensioner nut, tightening piece, tension shaft and expansion tightening wheel, described tensioner nut to be installed on described support and freely can to rotate and can not be shifted, described tension bolt is connected with described tightening piece through after described tensioner nut, described tightening piece is connected with described tension shaft, described expansion tightening wheel is installed on described tension shaft by bearing, described expansion tightening wheel walked around by described chain, described expansion tightening wheel is positioned at one side of described driving wheel and is positioned at the inner side of described chain.
In said structure, utilize the screw-thread fit of tension bolt and tensioner nut, the movement of tension bolt can be realized by rotary expansion jack panel, thus drive the movement of tightening piece, thus the distance changed between expansion tightening wheel and driving wheel, realize the object of adjusting chain degree of tightness.
For the ease of installing and regulating, described tensioner nut is installed on the top of described support, and described tension bolt is from top to bottom through described tensioner nut.
In order to dust-proof, be provided with protective housing outside described support, the nut of described tensioner nut and described tension bolt is placed in outside described protective housing, and described tightening piece, tension shaft and expansion tightening wheel are all placed in described protective housing.
In order to lead so that install to chain, described chain tensioning device also comprises and is placed in upper saw pulley in described protective housing and the axis of guide, the described axis of guide is installed on described support, described upper saw pulley is installed on the described axis of guide by bearing, described upper saw pulley walked around by described chain, and it is other and be positioned at the outside of described chain that described upper saw pulley is positioned at another of described driving wheel.
The beneficial effects of the utility model are:
The utility model is by arranging expansion tightening wheel on driving wheel side, coordinated the spacing regulated between expansion tightening wheel and driving wheel with tension bolt by tensioner nut, thus the angle that can change between chain and driving wheel finally reaches the object changing chain tensioner degree, for the tensioner effect that reel chain has also had, and outward appearance is neat, structure simple, easy accessibility, be convenient to maintenance, be easy to processing, reliable operation, also prevent tensioner nut too loosening by self-locking nut or double nut locking.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of chain tensioning device described in the utility model;
Fig. 2 is the A-A sectional view in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, chain tensioning device described in the utility model is installed on support 4, protective housing 1 is installed outside support 4, support is provided with driving wheel 8 by live axle 9, chain 7 is around on driving wheel 8, described chain tensioning device comprises tension bolt 2, tensioner nut 3, tightening piece 12, tension shaft 5, expansion tightening wheel 6, upper saw pulley 10 and the axis of guide 11, tensioner nut 3 is installed on the top of support 4 and freely can rotates and can not move, this mounting structure is conventional structure, be easy to realize, tension bolt 2 is from top to bottom connected with tightening piece 12 through after tensioner nut 3, tightening piece 12 is connected with tension shaft 5, expansion tightening wheel 6 is installed on tension shaft 5 by bearing (unmarked in figure), expansion tightening wheel 6 walked around by chain 7, expansion tightening wheel 6 is positioned at one side of driving wheel 8 and is positioned at the inner side of chain 7, the axis of guide 11 is installed on support 4, upper saw pulley 10 is installed on the axis of guide 11 by bearing (not shown), upper saw pulley 10 walked around by chain 7, it is other and be positioned at the outside of chain 7 that upper saw pulley 10 is positioned at another of driving wheel 8, the nut of tensioner nut 3 and tension bolt 2 is placed in outside protective housing 1, and tightening piece 12, tension shaft 5, expansion tightening wheel 6, upper saw pulley 10 and the axis of guide 11 are all placed in described protective housing.
As depicted in figs. 1 and 2, during application, by rotating forward tensioner nut 3, due to tensioner nut 3 can not move and with tension bolt 2 screw-thread fit, so tension bolt 2 can move up, tension bolt 2 drives tightening piece 12, tension shaft 5 and expansion tightening wheel 6 to move up, and the angle between chain 7 and driving wheel 8 also changes thereupon, and the tensioner degree of chain 7 is increased, otherwise, counterrotating tensioner nut 3, the tensioner degree of chain 7 just reduces, and is convenient to dismounting and maintenance after chain 7 is lax.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technological scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
