Abstract
The utility model provides a belt pulley of an engine. The middle part of the belt pulley (1) is provided with a first axle hole (4); and the belt pulley (1) is provided with a signal gear ring (2). When in use, the belt pulley (1) of the engine and the signal gear ring (2) are integrally installed on a crank axle, thus being capable of reducing the number of parts, simplifying the structure of the engine, and reducing the weight of the engine. In addition, the integral structure can effectively reduce the axial arrangement space, and can avoid assembling error among parts caused by split assembly and improve the reliability of running, thus leading the signals acquired by the signal gear ring (2) to be more accurate and reliable.
Description
Technical field
The utility model relates to engine art, relates in particular to the belt pulley on a kind of motor.
Background technique
Belt pulley provides subsidiary engine parts running required drives such as generator, water pump and air-conditioning as crankshaft front end power output transferring elements.And speed probe comes the collecting crankshaft tach signal by the signal gear ring that is arranged on the bent axle.Traditional belt pulley and signal gear ring are assembled on the bent axle separately, realize function separately respectively.Owing to need to adopt fastening pieces such as bolt, flat key that belt pulley and signal gear ring are contained in respectively on the bent axle, and adopt locating stud, seam etc. to carry out assembling and positioning, so increased number of components and parts, make the structure of motor become complicated, weight increases.In addition, the mode of this split assembling has increased axial arranged space, is easy to generate assembly error, has reduced operating reliability, thereby the signal that makes the signal gear ring gather is accurate inadequately.
The model utility content
The purpose of this utility model is to provide the belt pulley on a kind of simple in structure, reliable motor of running.
The utility model provides the belt pulley on a kind of motor, and the middle part of this belt pulley has first axis hole, wherein, has the signal gear ring on the described belt pulley.
Belt pulley on the motor that the utility model provides in use, belt pulley together with the signal gear ring as an integral installation on bent axle, so can reduce number of components and parts, simplify the structure of motor, make the weight of motor reduce.In addition, this kind integral structure can reduce axial arranged space effectively, and can avoid the assembly error between the parts that split assembling brings, improved operating reliability, thereby the signal that makes the signal gear ring gather is more accurately reliable.

Embodiment
As shown in Figure 1, the utility model provides the belt pulley on a kind of motor, and the middle part of this belt pulley 1 has first axis hole 4, wherein, has signal gear ring 2 on the described belt pulley 1.
As depicted in figs. 1 and 2, described signal gear ring 2 can be the flange that is formed on the outer circumferential face of described belt pulley 1 one ends, is formed with a plurality of teeth 3 on the outer periphery of this flange.Described flange can adopt variety of way well known in the art and belt pulley 1 to combine, for example described flange can be integrally formed with described belt pulley 1, also can be installed together by fastening pieces such as screw, bolt and described belt pulley 1, also can weld together with described belt pulley 1, perhaps the mode by punching press press-fits and is fixed on the belt pulley 1.Processing for convenience, preferably, described flange and described belt pulley 1 are integrally formed.Described flange can adopt variety of way well known in the art and described belt pulley 1 integrally formed, for example can adopt after the first punching press mode of spinning that belt pulley 1 and described flange is integrally formed, also can be belt pulley 1 and described flange is integrally formed by casting earlier the mode of afterwards processing.
In addition, as shown in Figure 3 and Figure 4, described signal gear ring 2 also can be the annular plate that is formed on 1 one end faces of described belt pulley, is formed with a plurality of teeth 3 on the outer periphery of this annular plate, and middle part that should the annular plate is formed with second axis hole of aiming at first axis hole 4 of described belt pulley 15.Described annular plate can adopt variety of way well known in the art and belt pulley 1 to combine, for example described annular plate can be integrally formed with described belt pulley 1, also can be installed together, also can weld together with described belt pulley 1 by fastening pieces such as screw, bolt and described belt pulley 1.Processing for convenience, preferably, described annular plate and described belt pulley 1 are integrally formed.Described annular plate can adopt variety of way well known in the art and described belt pulley 1 integrally formed, for example can adopt after the first punching press mode of spinning that belt pulley 1 and described annular plate is integrally formed, also can be belt pulley 1 and described annular plate is integrally formed by casting earlier the mode of afterwards processing.
The aperture of described first axis hole 4 and second axis hole 5 is determined according to the diameter of the bent axle that is mated, is not repeated them here.
The structure of the tooth 3 of described signal gear ring 2 be arranged as conventionally known to one of skill in the artly, do not repeat them here.
The work of the belt pulley on the motor that the utility model provides is described below.
Belt pulley on the motor that the utility model provides is contained in the front end of bent axle in use, when engine running, belt pulley 1 and signal gear ring 2 are together along with bent axle rotates, thereby belt pulley 1 passes to subsidiary engine parts such as generator, water pump, air-conditioning with power by belt, simultaneously, signal gear ring 2 passes to speed probe with tach signal, realizes the collecting treatment of tach signal.
Because the belt pulley on the motor that provides of the utility model is in use, belt pulley 1 together with signal gear ring 2 as an integral installation on bent axle, so can reduce number of components and parts, simplify the structure of motor, make the weight of motor reduce.In addition, this kind integral structure can reduce axial arranged space effectively, and can avoid the assembly error between the parts that split assembling brings, improved operating reliability, thereby the signal that makes signal gear ring 2 gather is more accurately reliable.
