Durable magnetic flywheel

Abstract

The invention discloses a durable magnetic flywheel which comprises a base made of aluminum alloy by compression molding and an impeller made of plastic, wherein a mounting pillar made of aluminum alloy is arranged on the base and integrally formed with the base by compression casting; outer ratchets are formed on the outer surface of the mounting pillar and matched with inner ratchets of an engine clutch block in a rotary retaining manner; the outer ratchets are arranged to be one third of the mounting pillar in length; the central part of the base bulges outwards to form a convex part; a fitting groove used for accommodating the engine clutch block is formed in the convex part; the axes of the mounting pillar, the convex part and the fitting groove are positioned in the same straight line; an annular side surface is arranged on the outer surface of the base in an encircling manner; the impeller comprises a first fixing ring and a second fixing ring which are concentrically arranged, as well as plastic blades uniformly distributed on each of the fixing rings in the circumferential direction. According to the durable magnetic flywheel, the blades are made of plastic, thereby being less prone to damage; the base is integrally formed by compression casting, so that the flywheel is light-weight, high in rotation speed, low in cost, high in working efficiency and good in heat dissipating effect.

Description

Technical field [0001] The invention belongs to the technical field of flywheels, and particularly relates to a durable magnetic flywheel. Background technique [0002] The flywheel is often used in the assembly of small engines. The traditional magnetic flywheel structure. During the assembly process of the whole machine, the flywheel needs to be connected with the clutch block. The clutch connection between the flywheel and the clutch drives the rotation of the drive shaft. Therefore, during the assembly process, a stainless steel sleeve needs to be provided at the upper end of the flywheel as a mounting post for the installation of the clutch block. This structure not only increases the cost of the parts, but also because the steel sleeve is small, it is inconvenient in the assembly process, making the installation process complicated. Secondly, both the steel sleeve and the clutch block are smooth surfaces, and only pressure clamping is used to realize the anti-rotation fit ...

AI Technical Summary

Problems solved by technology

This structure not only increases the cost of parts, but also makes the installation process complicated due to the small size of the steel sleeve, which is inconvenient in the assembly process.

Secondly, both the steel sleeve and the clutch block have a smooth surface, and only pressure clamping is used to realize the anti-rotation fit between the two. During the rotation process, the two are prone to slipping, which affects work efficiency.

Moreover, the base of the flywheel and the impeller are integrally die-cast, not only the cost is high, but also the blades pressed by the impeller are thinner, which is prone to breakage during the rotation of the flywheel

Due to the one-piece molding, the entire flywheel needs to be replaced if the blade is broken, and the maintenance cost is high
