Abstract
The utility model discloses a belt tight adjustment mechanism that rises for engine, including rise tight bracket, adjusting bolt and can by the adjusting bolt drive along adjusting bolt axial back -and -forth movement and be used for driving the belt and rise by the tight pulley and move the belt tight regulating block of adjusting that rises that rises, be provided with the bar guiding hole on the tight bracket that rises, but rise and be provided with that welt shape guiding hole moves and the guiding orientation piece of location on the tight regulating block, be provided with the guiding orientation piece owing to rise on the tight regulating block, not only can be in the good location of the downthehole formation of bar on the tight bracket that rises to be used for the drive to rise by the adjusting bolt of tight regulating block when making the assembly and aim at the regulating block screw hole easily, improve assembly efficiency, and form direction, limit function can remove in the tight regulating block welt shape hole of rising the time, appear rocking in preventing the use.
Description
Technical field
The utility model relates to engine art, particularly a kind of belt tension controlling mechanism.
Background technique
Belt is the conventional transmission part of engine accessory parts (as compressor or Generator), but is difficult to consistent due to the length of one group of belt, and strapping rubber easily stretches elongated, and belt needs the adjustment of regular tensioner.Dynamo belt tensioner controlling mechanism is by dynamo belt tensioner, and keeps belt to have certain expanding force, reduces vibration and the wearing and tearing of belt, to ensure the normal operation of motor.Existing belt tension controlling mechanism is many carries out compressing formation tensioner by driving regulating block to drive expansion tightening wheel to move to belt, but in practical set process, for driving the adjusting bolt of regulating block not easily to aim at regulating block tapped hole when easily there is assembling in belt tension regulating block, and the situation such as rocking of in use occurring of regulating block.
Therefore, be necessary to provide a kind of belt tension controlling mechanism, make its each parts alignment precision high, assembling is easy, and in adjustment process, guide effect is good, not easily occurs rocking.
Model utility content
In view of this, the utility model provides a kind of motor belt tension controlling mechanism, and its each parts alignment precision is high, and assembling is easy, and in adjustment process, guide effect is good, not easily occurs rocking.
Motor belt tension controlling mechanism of the present utility model, comprise tensioner bracket, adjusting bolt and can drive along adjusting bolt axially movable and for driving belt tightening wheel to move tensioner regulating block belt being carried out to tensioner adjustment by adjusting bolt, described tensioner bracket is provided with bar shaped pilot hole, described tensioner regulating block is provided with and can moves along bar shaped pilot hole and the guide-localization block of locating.
Further, tensioner regulating block is formed with expansion tightening wheel attachment hole, described guide-localization block is arranged around expansion tightening wheel attachment hole periphery.
Further, adjusting bolt and described tensioner regulating block form screw slider mechanism.
Further, tensioner bracket is formed with a snap arm, described adjusting bolt is stuck in the interior also single-degree-of-freedom of the draw-in groove formed between the body of snap arm and tensioner bracket and is rotatably assorted.
Further, tensioner regulating block is fixedly connected with belt tightening wheel with the expansion tightening wheel bolt of bar shaped pilot hole through expansion tightening wheel attachment hole by one.
The beneficial effects of the utility model: motor belt tension controlling mechanism of the present utility model, due to tensioner regulating block being provided with guide-localization block, not only can form good location in the bar hole on tensioner bracket, for driving the adjusting bolt of tensioner regulating block easily to aim at regulating block tapped hole during to make assembling, improve efficiency of assembling, and guiding, limit function can be formed when tensioner regulating block moves along bar hole, prevent from occurring in using process rocking.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation;
