Abstract
The utility model is a kind of for the automatic takeup in V belt translation and chain drive system, by regulating wheel, pole, bearing and formed by the Elastic Node Mechanism that pole and bearing link together, promote by the elastic force of Elastic Node Mechanism the tensioning that regulating wheel realizes transmission band chain.The utility model structure is simple, and make easily, reliable operation, both can realize unidirectional tensioning, also can conveniently realize two-way tensioning, may be used for various occasion.
Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of V belt translation and Chain conveyer automatic takeup.
Background technology
V belt translation and Chain conveyer are used widely in various low speed rotation system, and are mostly provided with automatic takeup, band chain can be made to remain suitable rate of tension, ensure to operate steadily.But the most complex structure of existing auto-tensioning technology, is unfavorable for practice.And some technology, although through updating, still there is the comparatively complicated or otherwise deficiency of structure and defect.If publication number is the patented technology of CN202646563U, tensioning connecting lever one end and regulating wheel pivot joint, and the other end and fixed axis pivot joint, structure is comparatively complicated, and manufacture difficulty is larger; Publication number is the patented technology of CN102330799A, regulating wheel is articulated in the elastic rod of a basing, although relatively simple for structure, but elastic rod needs sufficient length, be easy to twist and be displaced sideways, affect regulating wheel and chain interoperation, especially when transmission system is level, problem will be more serious.
Summary of the invention
The purpose of this utility model is to provide a kind of structure simple and the chain return automatic takeup of reliable operation, solves the deficiency in background technology.
To achieve these goals, the scheme that the utility model adopts is: rigidity pole one end and regulating wheel pivot joint, and the other end is connected with bearing by very short Elastic Node Mechanism; The connecting hole of bearing and Elastic Node Mechanism is chute hole, highly to regulate; Bearing settlement near two drives, can inside and outside driving-belt or driving-chain any side; Elastic Node Mechanism is made by the leaf spring of enough width.During work, regulating wheel passes through Elastic Node Mechanism elastic force to driving-belt or driving-chain applying effect, thus keeps effective object to have enough rates of tension all the time.Because Elastic Node Mechanism length is less, width is comparatively large, and pole is rigid member in addition, can ensure that it can not twist and be displaced sideways, and ensures the close fit of regulating wheel and band chain.Two covering devices with the use of, conveniently can realize the two-way tensioning of transmission system, and a bearing can be shared.
The utility model structure is simple, easily makes, reliable operation, easy to use and flexible, is applicable to various occasion.

Detailed description of the invention
Embodiment 1:
As depicted in figs. 1 and 2, for the unidirectional tensioning apparatus of one, wherein rigidity pole 2 one end is the fixed disc by cantilevered axle and regulating wheel 1 pivot joint, and the other end is the inboard rectangular slab being at least drilled with two fixing holes of deflection, and mid portion is the less rod-like structure in cross section; Bearing 4 is L shape, and its horizontal segment is at least drilled with two fixing holes, and its vertical section is longitudinally provided with chute-type fixing hole 5; Elastic Node Mechanism 3 is rectangular plate-like, be made up of leaf spring, its width is substantially equal with pole 2 rectangular slab one end width, its length should have certain distance between integrally mounted rear guarantee pole 2 and bearing 4, its thickness is determined according to the layout type of itself material characteristic, regulating wheel own wt, tensioning object own wt and transmission system, one end and pole 2 are riveted, and the other end is by fixing hole 6 and slide block type hold-down nut 5 and bearing 4 bolt.
As shown in Figure 3, unidirectional tensioning apparatus is installed between driving wheel 7 and driven pulley 9, is rotated counterclockwise when driving wheel 7 works, and is straightened condition and downside occurs lax on the upside of driving-belt or chain 8, regulating wheel 1 automatically on move, make to keep tensioning on the downside of driving-belt or chain 8.
Embodiment 2:
As shown in Figure 4, be the two-way tensioning apparatus of one, save a bearing 4 by the unidirectional tensioning apparatus in two cover embodiments 1 and combine.
As shown in Figure 5, two-way tensioning apparatus is installed between driving wheel 7 and driven pulley 9, and upper and lower two regulating wheels 1 act on driving-belt or chain about 8 both sides respectively.When driving wheel 7 is rotated counterclockwise, is straightened condition on the upside of driving-belt or chain 8, regulating wheel 1 moves in drive, on the downside of driving-belt or chain 8, then upwardly keeps tensioning down at lower regulating wheel 1; When driving wheel 7 turns clockwise, be straightened condition on the downside of driving-belt or chain 8, drive lower regulating wheel 1 to move down, on the upside of driving-belt or chain 8, then under upper regulating wheel 1 promotes, keep tensioning downwards.
