Abstract
The utility model is related to tensioning apparatus technical fields, specifically disclose a kind of adjustable tensioner, and including axis, tensioner arm and tensioning wheel, tensioner arm is sheathed on axis, it is characterised in that：The tensioning wheel is connect by balance staff with tensioner arm, and the side of tensioner arm is equipped with two convex blocks, and balance staff, which is swung, to be set between two convex blocks, and adjusting screw hole is respectively equipped on two convex blocks, the adjusting screw for adjusting and fixing balance staff swing angle is equipped in adjusting screw hole；The abrasion that belt deviation causes extra friction to bring can be reduced, makes belt more robust, operating is more steady.
Description
Technical field
The utility model is related to tensioning apparatus technical fields, and in particular to a kind of adjusting tensioning for belt tension fills
It puts.
Background technology
Tensioning apparatus is belt, common holding meanss on chain transmission system, its main feature is that belt, chain is kept to pass
Can possess appropriate tensile force during dynamic, so as to avoid belt slippage or avoid synchronous belt occur to jump tooth, de- tooth and drag
Go out.
At present, existing belt stretcher is typically all that the both sides of tensioning wheel are provided with boss, to limit belt
Position.But if belt deviation, belt will rub against the side of tensioning wheel always, and belt is caused in the course of time
Abrasion reduces the service life of belt.
Utility model content
In order to overcome tensioning apparatus there are the defects of, the utility model provides a kind of adjustable tensioner, can reduce
Belt deviation causes the abrasion that extra friction is brought, and makes belt more robust, and operating is more steady.
Technical solution is used by the utility model solves its technical problem：A kind of adjustable tensioner, including
Axis, tensioner arm and tensioning wheel, tensioner arm are sheathed on axis, it is characterised in that：The tensioning wheel passes through balance staff and tensioning
Arm connects, and the side of tensioner arm is equipped with two convex blocks, and balance staff, which is swung, to be set between two convex blocks, and adjusting spiral shell is respectively equipped on two convex blocks
Hole, the interior adjusting screw being equipped with for adjusting and fixing balance staff swing angle of adjusting screw hole.
As preference, the tensioner arm is the trapezoid block at right angle, two convex blocks are set on the oblique side of trapezoid block.
Further, adjusting screw hole there are two being all provided on two convex blocks.
Preferably, the tensioner arm turning set is set on axis, and the tensioner arm is equipped with fixing threaded hole, fixed spiral shell
The fixed screw for adjusting and fixing tensioner arm rotational angle is equipped in hole.
Preferably, the both ends of the axis are respectively equipped with mounting bracket.
The beneficial effects of the utility model are：Arbitrary adjustment can be carried out, while belt can be reduced to the tensioning degree of belt
Sideslip causes the abrasion that extra friction is brought, and makes belt more robust, and operating is more steady.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the usage state diagram of adjustable tensioner.
Specific embodiment
The technical issues of in order to solve the utility model, technical solution and advantageous effect are more clearly understood, below
With reference to attached drawing and embodiment, the utility model is further described.
As shown in Figure 1, a kind of adjustable tensioner of the utility model, including axis 1, tensioner arm 2 and tensioning wheel 3,
2 turning set of tensioner arm is set on axis 1, and tensioner arm 2 is equipped with fixing threaded hole, is equipped with to adjust and fix tensioning in fixing threaded hole
The fixed screw 7 of 2 rotational angle of arm.Tensioning wheel 3 is connect by balance staff 4 with tensioner arm 2, and the side of tensioner arm 2 is equipped with two convex blocks
5, as preference, tensioner arm 2 is the trapezoid block at right angle, two convex blocks 5 are set on the oblique side of trapezoid block, and balance staff 4, which is swung, is set on two
Between convex block 5, two adjusting screw holes are respectively equipped on two convex blocks 5, is equipped in adjusting screw hole and is swung for adjusting and fixing balance staff 4
The adjusting screw 6 of angle.
As shown in Fig. 2, the both ends of axis 1 are respectively equipped with mounting bracket 8, adjustable tensioner passes through mounting bracket 8
It is fixedly mounted on cross bar 9, unclamps fixed screw 7, tensioning wheel 3 suppresses belt 10, adjusts the rotational angle of tensioner arm 2, can be right
The tensioning degree of belt 10 carries out arbitrary adjustment, and be then locked screw 7, its angle is fixed.If the past tensioning of belt 10
When taking turns 3 side sideslip, it can squeeze balance staff 4 by adjusting the adjusting screw 6 on convex block 5 and rotate proper angle, so as to adjust tensioning
The gradient of wheel 3 makes the recovery of belt 10 fall the boss in the centre position of tensioning wheel 3, avoiding belt 10 again with tensioning wheel 3 and rubs
It wipes, reduces 10 sideslip of belt and cause the abrasion that extra friction is brought, make belt more robust, operating is more steady.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Any modification, equivalent replacement and improvement made within novel spirit and principle etc., should all fall the protection in the utility model
Within the scope of.
