Abstract
The utility model relates to a belt transmission type stepless speed-variator composed of a tank body, a transmission sprocket, a driven sprocket, an adjusting rod component, a lever mechanism, a stepless speed changing belt, a pressurizing spring, etc.; a transmission sprocket is arranged on a transmission shaft which is supported on the tank body; the driven sprocket is arranged on a driven shaft; the stepless speed changing belt is arranged on the transmission sprocket and the driven sprocket; the adjusting rod component for adjusting transmission and a lever mechanism are arranged in the tank body; the adjusting rod component is composed of a hand wheel, an adjusting screw rod and a cantilever rod connected with the adjusting screw rod. The space between two wheel bodies of the transmission sprocket is adjusted by an adjusting lever of the lever mechanism, and the adjusting lever of the lever mechanism driven by adjusting the screw rod. Adopting the way of adjusting rod and the lever to adjust, the utility model has simple structure and convenient adjustment; adopting the way of diagonal displacement to adjust speed, the adjustment is flexible and the utility model realizes stepless and constant speed adjustment; because the structure is simple, the cost is low.
Description
Technical field
The utility model relates to a kind of band transmission type stepless speed variator.
Background technique
Relevant by retrieval patent documentation, the present diagonal displacement formula stepless speed variator that does not retrieve employing band transmission the carry out stepless speed regulation identical as yet with the utility model structure.Existing stepless speed variator generally has hydraulic type and two kinds of structural types of band transmission.Because the speed governing of band transmission type stepless speed variator is convenient, simple in structure, so be widely used in weaving, dynamo-electric, metallurgical, automobile and other industries.But also, be subjected to certain restriction for production cost and the universal of use because structural reason makes structure go back more complicated comparatively speaking, thus be necessary existing band transmission type stepless speed variator is improved, better to increase economic efficiency.
Summary of the invention
The purpose of this utility model is that a kind of improvement on existing band transmission type stepless speed variator will be provided, and has a kind of diagonal displacement formula stepless speed variator simple in structure, easy to maintenance, that applicability is strong.
Technical characteristics of the present utility model is: at a kind of diagonal displacement formula stepless speed variator of considering to be designed on the basis simple in structure, easy to adjust to be made up of casing, transmission shaft, drive sprocket, driven sprocket, adjustable lever parts, leverage, driven shaft, cvt belt, pressing spring, adjusting nut, drive sprocket is housed on the transmission shaft, and is bearing on the casing; Driven sprocket is contained on the driven shaft, the end of driven sprocket is provided with pressing spring and is used to regulate the adjusting nut of pressure, cvt belt is contained on drive sprocket, the driven sprocket, also be provided with adjustable lever parts and a leverage that is used to regulate transmission in the inside of casing, described adjustable lever parts by handwheel, regulate screw mandrel and the cantilever lever that is attached thereto constitutes, and regulate spacing between drive sprocket two wheel bodys by regulating adjustment (adjusting) lever that screw mandrel promotes leverage; One end of the adjustment (adjusting) lever of described leverage is connected with casing by the bearing axle, and the other end links to each other with cantilever lever.The adjustment (adjusting) lever of described leverage is that an end connects by pivot pin, and the other end is the structural type of opening.
During work, transmission shaft drives drive sprocket, drives driven sprocket to driven shaft by cvt belt and rotates.When needs were adjusted the driven shaft output speed, the handwheel of rotation adjustable lever parts made and regulates the positive and negative rotation of screw mandrel, by the adjustment (adjusting) lever of cantilever lever promotion leverage, made regulating ring drive drive sprocket and produced displacement.When drive sprocket during to middle displacement, make cvt belt to the big position displacement of diameter, transmission radius increases, and then to the little position displacement of diameter, transmission radius reduces the band on the follower.Make drive sprocket to the axle head displacement if regulate, then to the little position displacement of diameter, transmission radius reduces cvt belt, and the band on the follower is then to the big position displacement of diameter, and transmission radius increases.The displacement of two wheel bodys by the diagonal angle during speed governing realizes infinite variable speed.
The utility model has the advantages that: owing to adopt the mode of adjustable lever and lever to regulate, thus make simple in structure, easy to adjust; Owing to adopt the mode of diagonal displacement to carry out speed governing, regulate flexibly thereby make, realize stepless uninterrupted speed governing; Because simple in structure, cost of production is low, so very big practical and popularizing value is arranged.
