Abstract
The utility model provides a pulley with adjustable pitch diameter, which is characterized in that one side or both sides of a fixing side wheel are provided with connecting screw threads and platform notch structures; both sides of the fixing side wheel are provided with two movable side wheels in a screw thread connection mode; consequently, a wheel groove with adjustable width and pitch diameter is formed. When the movable side wheel is rotated, the width of the wheel groove can be adjusted conveniently. Furthermore, the pitch diameter can be changed. The movable side wheel can be tightly fixed on a wheel hub by adopting the mode of connection through holding screws or keys. The utility model has the advantages of simple structure, convenient manufacture, installation, adjustment and use, and wide range of application.
Description
The utility model relates to the pulley element of translatory movement, specifically a kind of adjustable pitch diameter belt pulley.
We know: V-Belt Drive is the mechanical transmission form of extremely general translatory movement of a kind of use and moment of torsion, it is to be made of one group of Vee pulley V and V belt, it is big to have transferring power, speed ratio is steady, easy to install, advantages such as manufacturing cost is low, it has been widely used in industry, agricultural, building, numerous technical fields such as instrument and Motor Vehicle, at present, generally the Vee pulley V of Shi Yonging is to get on the bus at wheel hub by standard measure to make fixing race and form, in general, in case car system is finished, the wheel well width and the pitch diameter of Vee pulley V are changeless, when its working environment and technical requirements need change wheel well width or pitch diameter, the corresponding Vee pulley V of car system again then, and original Vee pulley V is discarded, this certainly will cause manpower, the significant wastage of material resources and financial resources.Chinese patent CN2112727U discloses the utility model patent of a kind of adjustable " speed change V belt wheel ", its race is to be made of one group of fixed edge and active edges, can active edges be moved by thrust disc, thrust-bearing and rolling disc by the flexible of driving and reversing mechanism, thereby change the wheel well width, and then change the drive wheel pitch diameter.But this " speed change V belt wheel " structure is comparatively complicated, and the manufacturing cost height is installed and used maintenance management and comparatively bothered, and is difficult to promote the use of.
The purpose of this utility model be on the prior art basis, propose a kind of simple in structure, reasonable in design, manufacturing cost is low, widely applicable, installation and maintenance and use and regulate adjustable extremely easily pitch diameter belt pulley.
The purpose of this utility model is achieved by the following technical solution:
A kind of adjustable pitch diameter belt pulley, it is to make the fixedly wheel hub of cincture, on the wheel hub of fixed edge wheel side, be shaped on connecting thread and platform breach, be threaded be fitted to the movable cincture of wheel hub and fixedly cincture constitute the race of adjustable-width and pitch diameter, the rotary moveable cincture can be regulated the width of race easily and then change the pitch diameter of belt pulley, on movable cincture, be separately installed with Cock screw, movable cincture can be fixed on the wheel hub firmly.
The utility model also has following technical characteristics:
In the dowel hole that wheel hub platform breach and movable cincture are done, be fitted with key, the movable cincture that regulates wheel well width and pitch diameter can be fixed on the wheel hub firmly, applicable to the working environment that transmits bigger torque load.
The utility model is to be shaped on connecting thread and platform breach structure on the wheel hub of fixing cincture one or both sides, adopt the mode that is threaded to be fitted with two movable cinctures in fixing cincture both sides, two movable cinctures and fixedly cincture constitute its width of can regulate, and then the race of change pitch diameter, can regulate the width and the pitch diameter of race easily according to the needs rotary moveable cincture of working environment technical requirements, according to the situation that transmits the torque load size, can adopt Cock screw or key ways of connecting that movable cincture is fixed on the wheel hub firmly gets final product, the utility model is simple in structure, make and install, regulate very easy to use, widely applicable, remarkable in economical benefits has excellent popularization and uses prospect.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Below in conjunction with accompanying drawing the utility model is further described:
A kind of adjustable pitch diameter belt pulley, it is to make the fixedly wheel hub 2 of cincture 1, on the wheel hub 2 of fixing cincture 1 one or both sides, be shaped on connecting thread 9,10 and platform breach 11, adopt the mode that is threaded on wheel hub 2, to be fitted with movable cincture 3 in fixing cincture 1 both sides, 4, movable cincture 3,4 constitute the race 7 of adjustable-width and pitch diameter with fixing cincture 1,8, movable cincture 3, hexagonal Cock screw 5 in being separately installed with on 4,6, according to technical requirements, hexagonal Cock screw 5 in unscrewing, 6, rotary moveable cincture 3,4 regulate belt pulley race 7,8 width and pitch diameter, hexagonal Cock screw 5 in tightening again, 6, can be with movable cincture 3,4 are fixed on the wheel hub 2 firmly.Under the situation of needs transmission than high pulling torque load, equipped key 12 in the dowel hole that the platform breach 11 and the movable cincture 3,4 of wheel hub 2 are done, movable cincture 3,4 can be fixed on the wheel hub 2 firmly, be specially adapted to transmit the working environment of bigger torque load.The utility model is simple in structure, and manufacturing installation, adjusting are manipulated very convenient, have splendid economic benefit.
