The utility model discloses simple structure, it is easy, with low costs to implement, through the rate of tension that the engine belt was adjusted to manual mode, adjusts convenient operation, swift, laborsaving to the good reliability that belt tensioning adjusted all is suitable for on polytype engine.
Description
Technical field
The utility model relates to a kind of engine belt pulley tension device, particularly relates to a kind of engine belt pulley manual tension device.
Background technique
In prior art, engine belt pulley many employings engine tensioner carries out tensioning to it automatically.On the Timing Belt that stretcher acts on motor or timing chain, guiding and tensioning are play a part to it, makes it be in best tensioning state all the time.Stretcher is generally divided into oil pressure and machinery two kinds of modes, and they can carry out the adjustment of rate of tension automatically to Timing Belt and timing chain.But stretcher is adopted in motor, add the cost of engine production, be unfavorable for the economic benefit of producing.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of engine belt pulley manual tension device.
Technical solutions of the utility model are as follows: a kind of engine belt pulley manual tension device, comprise the tension pulley with erection column, described erection column is through the waist type groove that tensioner bracket is arranged in left-right direction, and be fixedly connected with the belt tension block in waist type groove front, described belt tension block is threaded with adjusting bolt, and adjusting bolt and above-mentioned erection column perpendicular, the key of described adjusting bolt snaps in the U-groove bevel of opening upwards, load boss is formed with near the position of head in adjusting bolt, the head of adjusting bolt and load boss are positioned at the both sides of U-groove bevel.
Adopt above technological scheme, when needing adjusting belt tension degree, rotate adjusting bolt with hand, adjusting bolt original place is rotated, because adjusting bolt and belt tension block form feed screw nut pair, under the effect of adjusting bolt, belt tension block does straight line motion in adjusting bolt; Waist type groove is the space that erection column provides motion, and the function of also restricted erection column rotation simultaneously, while the motion of belt tension block, erection column and tension pulley move together, thus achieve the adjustment to belt tightening.The utility model is arranged in outside motor, is not only convenient to install, and saved cost of production, and adjustment operation is convenient, laborsaving.The head of adjusting bolt and load boss are positioned at the both sides of U-groove bevel, and adjusting bolt coordinates spacing by its head, load boss with U-groove bevel, can not move axially, thus ensure that the reliability that belt tension regulates.
In order to simplified structure, facilitate processing and fabricating, make spacing better reliability, described load boss is ring.
In order to protect the not modulated bolt head scratch in the surface of U-groove bevel, dispersion adjusting bolt head, to the pressure of connected piece, is provided with pad between the head and described U-groove bevel of described adjusting bolt.
Conveniently dismounting, makes belt tension block be connected with erection column firm, and described belt tension block is threaded with described erection column.
Guide pad is symmetrically arranged with in the left and right sides of described erection column, this guide pad and described belt tension block one-body molded, guide pad is arranged in described waist type groove and is slidably matched with waist type groove, the opposing side of two guide pads is arc surface, and the arc surface of guide pad is partly looped around the periphery of erection column shaft.Above structure directing block plays guiding, makes erection column only in waist type groove, do straight line motion, and can not teetertotter and circumference rotation, reliability is secure.
Beneficial effect: the utility model structure is simple, implement easily, cost is low, mode manually regulates the rate of tension of dynamo belt, adjustment operation is convenient, fast, laborsaving, and the good reliability that belt tension regulates, all applicable on polytype motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the decomposition texture schematic diagram of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model is made up of tensioner bracket 1, adjusting bolt 2, belt tension block 3 and belt pulley 4 etc.Wherein, one end of erection column 4a is connected with belt pulley 4, the other end of erection column 4a through the waist type groove 1a that tensioner bracket 1 is arranged in left-right direction, and is threaded with the belt tension block 3 in waist type groove 1a front, makes between erection column 4a and belt tension block 3 detachable.Belt tension block 3 is provided with two guide pad 3a also one-body moldedly, and these two guide pad 3a symmetries point occupy the both sides of erection column 4a, and two guide pad 3a are positioned at waist type groove 1a, and guide pad 3a and waist type groove 1a is slidably matched.The opposing side of two guide pad 3a is arc surface, and the arc surface of two guide pad 3a is circumferentially same, and the arc surface of guide pad 3a is partly looped around the periphery of erection column 4a shaft.
As shown in Figure 1 and Figure 2, belt tension block 3 is threaded with adjusting bolt 2, and this adjusting bolt 2 is perpendicular to erection column 4a, and adjusting bolt 2 parallels with waist type groove 1a.Position near head in adjusting bolt 2 is formed with load boss 2a, and load boss 2a is ring.Part in adjusting bolt between its head and load boss 2a snaps in the U-groove bevel 1b of opening upwards, and U-groove bevel 1b is integrally formed on tensioner bracket 1.Between the head and U-groove bevel 1b of adjusting bolt 2, be provided with the pad for compressing, pad is set in adjusting bolt 2.
Working principle of the present utility model is as follows:
When needing adjusting belt tension degree, the head of adjusting bolt 2 is rotated with hand, under the head of adjusting bolt 2 and the position-limiting action of load boss 2a, adjusting bolt 2 original place rotates, because adjusting bolt 2 and belt tension block 3 form feed screw nut pair, under the effect of adjusting bolt 2, belt tension block 3 does straight line motion in adjusting bolt 2; Waist type groove 1a is the space that erection column 4a provides motion, and the function of also restricted erection column 4a rotation simultaneously, while belt tension block 3 moves, erection column 4a and tension pulley 4 move together, thus achieve the adjustment to belt tightening.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
