Description
Technical Field
The utility model belongs to the technical field of a belt pulley, concretely relates to crank pulley for engine.
Background
Crankshaft pulley is the device commonly used that is used for transmitting the effort on the existing equipment, and at present, crankshaft pulley on the market can influence life and transmission stability because of inertia is big, in the not enough condition of belt pulley intensity, and engine crankshaft pulley is made by grey cast iron mostly now, does not have the design of lightening fabrication hole, and middle weight is piled up more.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims to provide a crank pulley for engine, it solves the problem that belt pulley intensity is not enough through spinning integrated into one piece's axle sleeve, wheel hub and wheel rim to can solve the big problem of inertia through the lightening hole of symmetrical design on the wheel rim right side.
In order to solve the above-mentioned object, the utility model adopts the following technical scheme:
the utility model provides a crank pulley for engine, includes spinning integrated into one piece's axle sleeve, wheel hub and wheel rim (3), its characterized in that: the wheel hub is located in the middle of the shaft sleeve and the wheel rim, mounting holes are evenly formed in the wheel hub, a plurality of lightening holes are symmetrically formed in the right side of the wheel rim, two groups of multi-wedge grooves including a first multi-wedge groove and a second multi-wedge groove are formed in the wheel rim, and a left edge and a right edge are arranged on two sides of each multi-wedge groove.
Preferably, the first and second multi-wedge grooves have different groove numbers, wherein the multi-wedge groove with the small groove number is close to the hub.
Preferably, the diameter of the hole of the shaft sleeve is larger, and the mounting hole is close to the rim.
Preferably, the inner side of the rim is provided with a drawing angle of 2 degrees.
Compared with the prior art, the utility model discloses possess following beneficial effect:
one, the utility model discloses a crank pulley for engine, through the axle sleeve of large aperture and the design of mounting hole, can make crank pulley's suitability better, can improve the reliability of rotating the in-process moreover through the installation of mounting hole, the mounting hole is close to the wheel rim and can increases pivoted stability.
Second, this practical crankshaft pulley for engine through a plurality of lightening holes that are equipped with on the wheel hub, can make the belt pulley cost lower when reducing the belt pulley material, and weight is lighter, and transmission inertia is little.
Third, this practical for the engine crankshaft pulley, the left edge and the right edge that polywedge groove both sides set up provide spacingly to the belt, prevent that the pivoted in-process belt is unexpected to drop.
