Several signal teeth on limit and a hypodontia window;The top of several signal teeth described is connected, between adjacent signal teeth
Form window.
Further, the edge at described three non-uniform screw mounting holes is respectively equipped with little convex flat platform.
Further, the circumferential edges at described disk body is provided with continuous print reinforcement.
Further, the height of the little convex flat platform at the edge of described screw mounting hole is 0.15mm to 0.25mm.
Further, the flange of described disk body is 90 ° with the card angle of disk body.
The invention have the advantages that
(1) owing to having three circular grooves at the periphery of the mounting-positioning holes at disk body center, mounting-positioning holes and bent axle are made
Axle journal forms three sections of cooperations, thus at ensureing these three sections while quality of fit, it is possible to decrease the abrasion of drift, reduce
The weight of signal panels.
(2) due to dynamic balancing groove and mounting-positioning holes and stamping-out molding of circular groove, decrease blank operation, carry
High manufacturing efficiency.
(3) stamp out reinforcement due to disk body cylindrical side area, improve the rigidity of disk body, and improve collecting crankshaft
The reliability of tach signal.
(4) stamp out 0.2mm(millimeter due to the bolt hole periphery of disk body Yu bent axle contact surface) left and right little convex flat platform, and
Little convex flat table top is long-pending less, it is possible to well ensures flatness, improves the quality coordinated with bent axle.
(5) it is connected due to the end of signal teeth, forms window-like between adjacent signals tooth, be possible not only to strengthen whole disk body
Rigidity, increase reliability, and be possible to prevent transport and assembling during because of collision cause signal teeth deformation.
(6) simple in construction, quality are little, can be one time punching molded, and low cost is easy for installation, it is adaptable to various gasoline engines..
