Abstract
The utility model relates to a self-locking tensioning wheel mechanism which comprises a supporting arm, a tensioning wheel and a tensioning spring, wherein the middle segment of the supporting arm is movably connected with one end of an L-shaped tensioning support through a rotary shaft; a pull rod retention hole is formed in the other end of the L-shaped tensioning support, and the tensioning wheel is arranged at the corner of the L-shaped tensioning support; and one end of the L-shaped tensioning support is also connected with the top of the supporting arm through the tensioning spring. The self-locking tensioning wheel mechanism has the advantages of simple structure, convenience in operation and high working efficiency.
Description
Technical field
The utility model relates to the driving belt controlling device of agro-farming machinery, is specifically related to a kind of self-locking Idle wheel mechanism.
Background technique
The tension pulley of agro-farming machinery is very important assembly in the power transmission.During operation in the past, the effect of the long-term tension power of belt will inevitably produce plastic deformation and relaxation phenomenon occur, influences the transmission of power; During actual job, the staff makes it obtain required tension force often by adjusting the centre distance of two belt wheels, and its operation is consuming time, take a lot of work.
Summary of the invention
At the deficiencies in the prior art, problem to be solved in the utility model provides a kind of simple in structure, and operation is a kind of self-locking Idle wheel mechanism efficiently.
For solving the problems of the technologies described above, a kind of self-locking Idle wheel of the utility model mechanism comprises support arm, Idle wheel, tension spring; Described support arm stage casing flexibly connects by rotating shaft and " L " shape tensioning support one end; Described " L " shape tensioning support the other end is provided with the pull bar fixed hole, and " L " shape tensioning support corner is provided with Idle wheel; One end of described " L " shape tensioning support also is connected with the top of support arm by tension spring.
The utility model self-locking Idle wheel mechanism is fixed on driving belt one side, and the Idle wheel of the self-locking Idle wheel mechanism after fixing is parallel with the belt outside; When belt slack influences the power transmission, the staff drives " L " shape tensioning support by pull bar fixing on the pull bar fixed hole and clockwise rotates along rotating shaft, when " L " shape tensioning support rotates, the Idle wheel that its corner arranges progressively compresses belt, normal operation behind the belt recovery tension force.In the operation process, tension spring is according to the degree of tightness state Automatic Fine Tuning of belt, so that it reaches best working state.
The utility model is simple in structure, and operation is convenient efficient, and it can regulate the driving belt elasticity automatically increases power output.
Description of drawings
Fig. 1 is the front view of the utility model self-locking Idle wheel mechanism;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is embodiment's one operation schematic representation;
Fig. 4 is embodiment's two operation schematic representation.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As Fig. 1, Fig. 2, shown in Figure 3, a kind of self-locking Idle wheel of the utility model mechanism comprises support arm 5, Idle wheel 2, tension spring 3; Described support arm 5 stage casings flexibly connect by rotating shaft 4 and " L " shape tensioning support 1 one ends; Described " L " shape tensioning support 1 the other end is provided with pull bar fixed hole 6, and " L " shape tensioning support 1 corner is provided with Idle wheel 2; One end of described " L " shape tensioning support 1 also is connected with the top of support arm 5 by tension spring 3.
Driving belt C one side is fixed in the utility model self-locking Idle wheel mechanism, the Idle wheel 2 of the self-locking Idle wheel mechanism after fixing is parallel with the driving belt C outside, when driving belt C is lax when influence the power conveying, the staff drives " L " shape tensioning support 1 by pull bar 7 and clockwise rotates along rotating shaft 4, when " L " shape tensioning support 1 rotates, the Idle wheel 2 that its corner arranges progressively compresses driving belt C in parallel, normal operation behind the driving belt C recovery tension force; Can produce the pulling force self-locking by the tension spring 3 of " L " shape tensioning support 1 and 5 settings of support arm during operation.
Embodiment one:
As shown in Figure 3, occur lax after the high-intensity operation of driving belt C, its power transfer efficiency reduces, the staff drives " L " shape tensioning support 1 by pull bar fixing on the pull bar fixed hole 67 and clockwise rotates along rotating shaft 4, the Idle wheel 2 that its corner arranged when " L " shape tensioning support 1 rotated is compacting driving belt C progressively, and driving belt C recovers proper functioning in tight back; Tension spring 3 can make it be in optimum Working all the time according to the degree of tightness state Automatic Fine Tuning of belt C.
Embodiment two:
As shown in Figure 4, during concrete enforcement, can be according to actual needs, Idle wheel 2 also can parallelly place driving belt C inboard, after driving belt C is lax, the staff drives " L " shape tensioning supports 1 by pull bar 7 and rotates counterclockwise along rotating shaft 4, arrange it on Idle wheel 2 outwards compress driving belt C simultaneously, its normal operation after driving belt C tension force recovers.Tension spring 3 can make it be in optimum Working all the time according to the degree of tightness state Automatic Fine Tuning of belt C.
A kind of self-locking Idle wheel of the utility model mechanism structure is simple, and operation is convenient, efficient, can regulate driving belt C elasticity automatically, makes it remain optimum Working.
