Embodiment 3

[0037] Example 3 of coating powder: the coating powder is composed of the following materials according to the mass fraction ratio: 75% of ultrafine calcium carbonate with a particle size of 0.01-0.08 μm, 20% of atomized copper powder of -200 mesh, and 0.75% of colloidal graphite. Micro wax powder is 0.75%, binder is 3.5%.

[0038] The adhesive is ceramic tile adhesive or epoxy resin adhesive.

[0039]2. The body 2 of the insert sleeve is pressed into an integrated structure with the boot cover 1 of the outboard motor when the boot cover 1 is thermally expanded. Select various working parameters through the automatic press-in equipment, and control the press-in and pause time.

[0040] 3. When making the insert sleeve body 2, the precision of all the external dimensions of the insert sleeve body 2 is within the range of 0-0.04mm in advance.

[0041] 4. At the same time, when making the insert sleeve body 2, the gap between all the external dimensions of the insert sleeve bod...

Abstract

The invention discloses a wear-resistant sleeve for a starting wheel of an outboard engine and an assembly process method thereof. The wear-resistant sleeve is characterized in that an insert sleeve body is sequentially provided with a plurality of sections with outer diameters from large to small, wherein a middle section is a cone; the outer diameter of the section with the minimum diameter in three sections is in interference fit with an bearing inner hole of a starting cover of the outboard engine; a plurality of lug bosses extending in a radial direction are arranged at the end of the section with the minimum diameter of the insert sleeve body; an arc chamfer is arranged at the end of the inner hole of the section with the minimum diameter of the insert sleeve body; and the insert sleeve body and the starting cover of the outboard engine are laminated into an integrated structure when the starting cover of the outboard engine is in a thermal expansion state. The insert sleeve bodyformed through compression molding by adopting bakelite powder has high wear resistance and high accuracy and is free from the influence of outward friction force when a nylon starting rope is pulledso as to avoid falling; the fluffing and breaking phenomena of the nylon starting rope are reduced, and the personal safety of a user is ensured; and the qualified rate of starting cover combinationproducts is greatly improved.

Description

technical field [0001] The invention relates to the technology of an outboard motor of a hull engine, in particular to a wear-resistant sleeve for a starting wheel of an outboard motor and an assembly method thereof. Background technique [0002] There are various kinds of wear-resistant bushings in the prior art, and there are various designs according to the characteristics of specific products. For example, the patent publication number is CN101387197A, a non-magnetic wear-resistant sleeve of a logging-while-drilling tool used to protect drill string type petroleum drilling downhole instruments against wear. Groove, composed of trapezoidal diamond strips: 9 trapezoidal grooves are uniformly distributed on the outer edge of the non-magnetic wear-resistant sleeve body, and the protruding part of the wear-resistant sleeve body is uniformly cut by wire cutting. Cut the cut non-magnetic trapezoidal strips into 20mm short sections, put the diamond and nonmagnetic trapezoidal s...
