Technical field
The utility model relates to belt auto-tensioning equipment technical field, relates in particular to a kind of automatic belt tensioning device.
Background technique
The application of belt is very extensive, and the little life household electrical appliances that arrive, arrive greatly train steamer, invariably need belt to carry out connection for transmission.The model utility of belt, can be described as a large invention of mechanical field.The belt of various materials is not elastomer completely, under the effect of pretightening force, after running after a while, will relax because of plastic deformation, cause pulling force to reduce, in order to ensure bel-drivenn ability, need make regular check on the numerical value of pulling force, if find deficiency, need re-tensioning normally to work.In prior art, in the time that the centre distance between drive pulley regulates, also need to use tension device.
Model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, automatic belt tensioning device that tensioning dynamics is stable is provided.
For solving the problems of the technologies described above, the technological scheme the utility model proposes is:
A kind of automatic belt tensioning device, comprise bearing, belt pulley, ratchet limit stoper and rocking arm, one end of described rocking arm is articulated with on bearing, described belt pulley is connected in the other end of described rocking arm, and described ratchet limit stoper is installed on bearing and coordinates to limit the rotation angle of rocking arm with rocking arm.
Described rocking arm and described ratchet limit stoper are installed on described bearing by a rotating shaft, and described rocking arm and described ratchet limit stoper are all sheathed in rotating shaft, and can rotate by phase countershaft, and described rotating shaft is fixedly connected with bearing.
Described ratchet limit stoper comprises ratchet and pawl, and described ratchet is articulated with on bearing, and described ratchet is installed in a side of ratchet to form engagement fit with ratchet.
Described rocking arm and ratchet hinge are all coaxial shape by rotating shaft and are articulated with on described bearing.
In described rotating shaft, be arranged with torque spring, described torque spring one end is fixedly connected with rocking arm, and the other end is fixedly connected with described ratchet, and is tensioning shape and is installed between rocking arm and ratchet.
Compared with prior art, the utility model has the advantage of:
Automatic belt tensioning device of the present utility model, is adjusted, is limited the pendulum angle of rocking arm by ratchet limit stoper, thereby the position of idler is changed, and adjusts the tensioning dynamics of belt.The utility model is by regulating the occlusal position of ratchet and pawl to regulate the position of belt pulley, and ratchet and pawl coordinates stable, ensures that after adjusting, the tensioning dynamics of belt keeps certain numerical value.The utility model is simple in structure, and production and processing is easy and expense is cheap.
Brief description of the drawings

Embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is further described.
Fig. 1 to Fig. 3 shows a kind of embodiment of the utility model automatic belt tensioning device, comprise bearing 1, belt pulley 2, ratchet limit stoper and Rocker arm 5, belt 7 is set around on belt pulley 2; one end of Rocker arm 5 is articulated with on bearing 1; belt pulley 2 is connected in the other end of Rocker arm 5, and ratchet limit stoper is installed on bearing 1 and coordinates to limit the rotation angle of Rocker arm 5 with Rocker arm 5.Adjust, limit the pendulum angle of Rocker arm 5 by ratchet limit stoper, thereby the position of belt pulley 2 is changed, adjust the tensioning dynamics of belt 7.
In the present embodiment, ratchet limit stoper comprises ratchet 3 and ratchet 4, ratchet 3 is articulated with on bearing 1, ratchet 4 is installed in a side of ratchet 3 to form engagement fit with ratchet 3; Rocker arm 5 and ratchet 3 are all coaxial shape by a rotating shaft 8 and are articulated with on bearing 1; Rocker arm 5 and ratchet 3 can rotate by phase countershaft 8, and rotating shaft 8 is fixedly connected with bearing 1.
In the present embodiment, in rotating shaft 8, be arranged with torque spring 6, torque spring 6 one end are fixedly connected with Rocker arm 5, the other end is fixedly connected with ratchet 3, and be tensioning shape and be installed between Rocker arm 5 and ratchet 3, ratchet 3 and Rocker arm 5 form the rotation of opposite direction by the lashing force of torque spring 6, the rotation of ratchet 3 is regulated and is locked by ratchet 4; rotation of Rocker arm 5 limits by belt 7; ratchet 3 and ratchet 4 coordinate stable; ensure that after adjusting, the tensioning dynamics of belt 7 keeps certain numerical value, prevents that tensioning torque spring 6 is lax.
Taking the brush belt in Separators and High Tension Separation as example, working principle of the present utility model is described:
In bearing 1 and high tension separation, the support of cylinder electrode 9 is integrated, belt 7 is set around on central shaft, the central shaft of rolling hairbrush 10 and the belt pulley of tensioning 2 of cylinder electrode 9, when driving source drives cylinder electrode 9 to rotate, by the gearing of drivign belt 7, the belt pulley 2 of rolling hairbrush 10 and tensioning can drivenly rotate.In the time of rolling hairbrush 10 shift in position, ratchet 3 and Rocker arm 5 form the rotation of opposite direction, regulate the occlusal position of ratchet 3 and ratchet 4, make the clockwise or counterclockwise rotation of ratchet 3, torque spring 6 compresses Rocker arm 5 makes the belt pulley 2 of tensioning stressed, the position of the belt pulley 2 of tensioning changes, thereby can adjust the tensioning dynamics of belt 7.
