Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail;

[0018] Such as figure 1 , 2 As shown, it is an assembly drawing of the flywheel assembly of the present invention, which includes a signal disc 1, a ring gear 2 and a flywheel body 3, and a flywheel mounting hole 4 is provided on the flywheel body 3 for connecting the flywheel body 3 to the crankshaft of the engine. Flywheel installation pin holes 5 and positioning pins 6 are also set on the flywheel body 3 for the positioning of the installation of the clutch cover. A production process for a flywheel assembly for an automobile engine is characterized in that it includes the following steps:

[0019] (1) Production of signal discs: Take steel plates of corresponding thickness, blank and punch holes on the die, and punch out signal disc blanks with crankshaft holes at one time, then position the signal disc blanks and punch out the edge of the ...

Abstract

The invention discloses a production process of a flywheel assembly for an automobile engine. The production process of the flywheel assembly for the automobile engine comprises the following steps: (1) a signal disc is produced; (2) a gear ring is produced; (3) a flywheel body is produced; (4) assembling is conducted in a pressing mode, namely, the signal disc produced in the first step and the gear ring produced in the second step are assembled on the flywheel body produced in the third process, wherein the signal disc is riveted with a connecting disc at first, and then the gear ring is heated for 30-60 minutes under the environmental temperature of 200-300 degrees, is arranged on the flywheel body in a hot pressing mode through a pressing assembling machine after being taken out and is naturally cooled; (5) gravity balancing is adjusted; and (6) cleaning and packaging are conducted. Because the gear ring is heated for 30-60 minutes under the environmental temperature of 200-300 degrees, is arranged on the flywheel body in a hot pressing mode through the pressing assembling machine after being taken out and is naturally cooled, quality of the flywheel assembly is greatly improved, production steps are reduced, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile parts manufacturing, and more specifically relates to a production process of a flywheel assembly for an automobile engine. Background technique [0002] The flywheel is the key starting part of the automobile engine. It is generally a thick disc. Its weight and balance performance seriously affect the performance of the engine. Therefore, it has certain weight requirements and certain dynamic balance requirements. With the improvement of automobile engine performance requirements, the requirements for flywheel dynamic balance also increase accordingly. [0003] The traditional flywheel assembly consists of a flywheel disc, a flywheel ring gear, and a triangular support plate. The flywheel ring gear is shrunk onto the flywheel disc to form a flywheel tray assembly. The flywheel disc has rectangular teeth for transmitting speed signals. The flywheel disc Connected with the engine crankshaft, th...
