Description
Technical field
The present invention relates to vessel engines shipboard technology, especially a kind of shipboard starting wheel wear-resistant sleeve and its assembly side
Method.
Background technique
Anti-wearing liner in the prior art is numerous in variety, has various designs according to the feature of specific product.Such as
Patent publication No. is CN101387197A, it is a kind of protect drill stem type oil drilling downhole instrument abrasionproof LWD tool without
Magnetic wear-resistant sleeve, by no magnetic wear-resistant sleeve ontology, the outer dovetail groove of wear-resistant sleeve, both ends dovetail groove, trapezoidal diamond long strip block composition: in nothing
Magnetic wear-resistant sleeve ontology outer rim is equipped with the outer dovetail groove of 9 uniformly distributed wear-resistant sleeves, on wear-resistant sleeve carcass protrusion part, with wire cutting work
Skill cuts uniform 9 dovetail grooves, the pipe nipple that 20mm long is cut into without the trapezoidal item of magnetic that will be cut down, by diamond and without magnetic ladder
Shape pipe nipple intersection is put into the dovetail groove of wear-resistant sleeve carcass, after all dovetail grooves are filled up, uses argon arc welding welding；In wear-resistant sleeve
Both ends are equipped with both ends dovetail groove.A kind of for another example wear sleeve that patent publication No. designs for CN102812272A, including along axial direction
It is extended with the sleeve part of cylindrical sliding sealing surface, radially from the outwardly extending flange section in sleeve part, and connection
Sleeve part and flange section and the predetermined fracture zone for making flange section be easy to separate from sleeve part, in addition to this further include setting
Tearing position on flange section, so that flange section is easy to radially tear to predetermined fracture zone.
In the shipboard field for being installed on propelling motor on the outside of hull (ship side), the outside of stern trimming flag is usually hung on, again
Claim machine outside.During shipboard for many years is manufactured, there is a component manufacturing to annoying industry development always,
And become a problem.Since the outer ring of starting wheel is wrapped the nylon start rope of 3-4 circle, whenever needing to start engine,
With 1.5 meters of speed per second pull-out, bushing (the bakelite part) of start rope and exit site can generate biggish frictional force, be at this time
Make nylon rope institute through there are some burrs on access, under multiple working in reciprocating mode state, will also result in nylon rope gradually fluffs, directly
To fracture, to cause shipboard user's personal injury.In prior art, entire starting cover is substantially infused using engineering plastics
It moulds, and bakelite part will be inlayed wherein, bakelite part can bear higher frictional force and be unable to undergo gently to hit.In injection moulding process
In, mold is often performed fighting once, and bakelite part is just hit once, is not kissed if the external form of bakelite part and the depressed section of mold have
It closes, just will affect the quality of moulding, there is the possibility for leading modeling in the inside of especially bakelite part, so yield rate is low.
