Description
Technical field
The utility model relates to a kind of belt pulley, relates in particular to motor car engine twin shaft belt pulley, belongs to mechanical field.
Background technique
Belt pulley transmission advantage is a lot, and for example the belt pulley transmission can relax load impacting, and the belt pulley transmission operates steadily, low noise, low vibration; Belt pulley transmission simple in structure; easy to adjust; the belt pulley transmission is strict unlike engagement driving for manufacture and the installation precision of belt pulley; the belt pulley transmission has the function of overload protection; the diaxon centre distance regulation range of belt pulley transmission is larger etc., and these advantages make the application area of belt pulley originally wider.Its middle belt pulley is also component the most frequently used in motor car engine, but belt pulley of the prior art mostly exists following problem, 1), belt pulley of the prior art is established line bearing, uses the mode of injection machine injection moulding to realize by injection mould; 2), nonstandard bearing preparation process is more complicated, answers the reason that demand is little, domestic large bearing producer does not produce basically, little bearing machining factory is based on reasons such as equipment, technical forces, quality of product can not be guaranteed, and therefore, directly affects the performance of motor car engine; 3) nonstandard bearing is because of above reason, and purchasing price is more expensive, and purchase quantity and time can not be guaranteed; Therefore, a kind of new structure of exigence solves above-mentioned technical problem.
Summary of the invention
The utility model, just for the technical problem existed in prior art, provides a kind of twin shaft belt pulley simple in structure, easy to operate, lower-cost, and this belt pulley adopts standard rolling bearing to produce, and buying is convenient, and quality is guaranteed, and cost is lower.
To achieve these goals, the technical solution of the utility model is as follows, a kind of twin shaft belt pulley, it is characterized in that, described twin shaft belt pulley comprises the belt pulley shell, is arranged on the standard rolling bearing of enclosure, described standard rolling bearing inside is provided with back shaft, between described standard rolling bearing and back shaft, press-fit fixing, described standard rolling bearing be set to two, be separately positioned on the both sides of belt pulley.This technological scheme overall structure is simple, and production and processing is convenient, and belt pulley is that standard rolling bearing uses the mode of injection machine injection moulding to realize by injection mould, the Application standard Production of bearing, and manufacturing process is simple and convenient, is convenient to control; Automobile tension pulley application specific standard Production of bearing producer is many, and because amount of purchase is larger, the manufacturing equipment versatility is good, and quality and quantity all can be guaranteed.
As a kind of improvement of the present utility model, described back shaft comprises upper support axle and lower support axle.Back shaft is the common machine workpiece, and quantity and quality can be guaranteed, and processing cost is lower.
As a kind of improvement of the present utility model, on described upper and lower back shaft, be provided with the flange projection, described flange projection press-fits fixing with standard rolling bearing.Back shaft and bearing press mounting, upper and lower back shaft all has the flange projection, after compression, makes two bearings and upper and lower back shaft become an integral body.
As a kind of improvement of the present utility model, on described upper support axle, be provided with step, described step is for equipping bolt.The upper support axle has the countersunk head step, is convenient to installation and the locking of assembling bolt, and product appearance is similar to former design, and usability is all higher than former deisgn product.
With respect to prior art, advantage of the present utility model is as follows, 1) overall structure is simple, production and processing is convenient, 2) belt pulley is that standard rolling bearing uses the mode of injection machine injection moulding to realize by injection mould, the Application standard Production of bearing, manufacturing process is simple and convenient, is convenient to control; 3) automobile tension pulley application specific standard Production of bearing producer is many, and because amount of purchase is larger, the manufacturing equipment versatility is good, and quality and quantity all can be guaranteed; 4) back shaft is the common machine workpiece, and quantity and quality can be guaranteed, and processing cost is lower; 5) back shaft and bearing press mounting, upper and lower back shaft all has the flange projection, after compression, makes two bearings and upper and lower back shaft become an integral body, the upper support axle has the countersunk head step, be convenient to installation and the locking of assembling bolt, product appearance is similar to former design, and usability is all higher than former deisgn product.
