Abstract
The utility model relates to flywheels for engine, including a flywheel body. A mounting hole and a connecting hole are arranged at the center of the flywheel body and a friction plate fixing groove and a dust exhaust passage are disposed on the flywheel body; a balance hole is arranged on the flywheel body and several sensor holes are arranged on the outer annulus of the flywheel body; because the balance hole is disposed on the flywheel body, the rotational balance of the flywheel is ensured by the balance hole and the rotational balance of the flywheel is good; because several sensor holes are arranged on the outer annulus of the flywheel body, signal collection is realized via sensor holes; the flywheel body and signal collection structure is an integrated structure, and the structure of the flywheel is simple, and easy processing, greatly reduces the cost of production.
Description
Technical field
The utility model relates to a kind of motor component, relates to a kind of motor flywheel specifically.
Background technique
Motor is arranged between motor car engine and the clutch with flywheel, usually flywheel is directly installed on the engine crankshaft rear end by bolt, be used for the balance transferring power, and bent axle is turned round in each work cycle evenly, to guarantee that cycle irregularity is in claimed range.In addition, flywheel can also guarantee the stability of motor empty wagons running, and motor is operated steadily, and improves the working life of bent axle.
The structure that now usually need flywheel be provided with signals collecting, at present, corner signal dish in the existing fly wheel assembly and flywheel body are split type, corner signal dish and flywheel body are processed respectively, machine laggard luggage and join, the processing essence is had relatively high expectations, and installs to cooperate difficulty big, improved cost of production, and the spin balancing of assembling rear flywheel is difficult for guaranteeing.
The model utility content
Problem to be solved in the utility model is at above problem, and the motor flywheel that a kind of cost of production is low, spin balancing is good is provided.
For addressing the above problem, the technological scheme that the utility model adopted is: a kind of motor flywheel, comprise the flywheel body, the center of described flywheel body is provided with mounting hole and attachment hole, described flywheel body is provided with friction plate mounting groove and dust discharge passage, described flywheel body is provided with equalizing orifice, and the excircle of described flywheel body is provided with the plurality of sensors hole.
A kind of concrete optimized project, described equalizing orifice are positioned at the outer circumferential position place near the flywheel body.
As a kind of optimized project, described gauge hole is along the radially setting of flywheel body.
A kind of concrete optimized project, the axis of described first gauge hole is 80 ° with the angle of vertical center line, all the other gauge holes circumferentially arranging counterclockwise from first gauge hole along the flywheel body.
A kind of concrete optimized project, the angle between the axis of first gauge hole and the axis of last gauge hole is 18 °, the angle between the axis of adjacent gauge hole is 6 °.
A kind of concrete optimized project, beginning in the counterclockwise direction from first gauge hole, the 13 gauge hole is provided with the setting circle cambered surface.
A kind of concrete optimized project, the quantity of described gauge hole are 58.
A kind of concrete optimized project, described dust discharge passage comprises dust discharge groove and dust exhausting hole, described dust discharge groove and dust exhausting hole are communicated with.
The utility model is taked above technological scheme, have the following advantages: because the flywheel body is provided with equalizing orifice, so can guarantee the spin balancing of flywheel by equalizing orifice, the spin balancing of flywheel is good, again because the excircle of flywheel body is provided with the plurality of sensors hole, so, can realize the collection of signal by gauge hole, flywheel body and signal acquisition structure are structure as a whole, and flywheel structure is simple, be easy to process, greatly reduce cost of production.
The utility model is described in further detail below in conjunction with drawings and Examples.
