Abstract
The utility model discloses a prevent copper sheathing rotary device, include, copper sheathing and main arm hinge ear, the copper sheathing insert in the earhole of main arm hinge ear, inboard the opening of copper sheathing have the half -thread hole, the half -thread hole has also been opened to the earhole of the main arm hinge ear that corresponds, two half -thread hole shapes become a complete screw hole. Copper sheathing and the cooperation of main arm hinge ear to open threaded hole at copper sheathing and main arm hinge ear, and cooperate with the screw, can prevent effectively that the copper sheathing from cutting with scissors the rotation of ear relatively.
Description
Technical field
The utility model relates to a kind of anti-copper sheathing whirligig.
Background technique
Copper sheathing is comparatively extensive in machinery design ap-plication, is usually used in improving component local wear resistance.The effect of " sliding bearing " can be played under liquid lubrication condition, greatly reduce friction and surface abrasion.For ensureing using effect, preventing the relative rotation in work between copper sheathing with mounted structural member, accelerated wear test, between copper sheathing and mounted structural member, generally adopting interference fit.During as installed, often utilize principle of expanding with heat and contracting with cold, first copper sheathing is dipped in the low temperature environments such as liquid nitrogen and installs again after cooling.Even so, in equipment working procedure, because the factors such as heavy duty, friction and vibration still there will be the situation of copper sheathing rotation, accelerated wear test, makes the practical effect of copper sheathing have a greatly reduced quality, and is unfavorable for the Long-Time Service of equipment.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of anti-copper sheathing whirligig, effectively can prevent the rotation of copper sheathing.
To achieve these goals, the technical solution adopted in the utility model is: a kind of anti-copper sheathing whirligig, comprise copper sheathing and principal arm hinge ear, described copper sheathing loads in the earhole of principal arm hinge ear, the assembling fitting surface that copper sheathing and corresponding principal arm cut with scissors ear earhole is joined and is drilled with at least one tapped hole, cut with scissors inside ear earhole with principal arm outside described copper sheathing and respectively account for half tapped hole, outside each copper sheathing, partial thread hole and corresponding principal arm cut with scissors partial thread hole inside ear earhole and form a complete thread hole.
Described copper sheathing inside has lubrication channel.
Described copper sheathing and principal arm cut with scissors to join between ear earhole and bore several tapped holes.
Described tapped hole is provided with screw.
Copper sheathing and principal arm cut with scissors ear and coordinate, and cut with scissors ear fitting surface and have tapped hole, and install attachment screw with screw hole at copper sheathing and principal arm, can effectively prevent copper sheathing relative to cutting with scissors rotating of ear.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is copper sheathing and principal arm hinge ear plan view.
1, copper sheathing, 2, principal arm hinge ear, 3, tapped hole, 4, lubrication channel, 5, screw.
Embodiment
Below in conjunction with accompanying drawing 1, the utility model is described in further detail.
As shown in Figure 1, a kind of anti-copper sheathing whirligig, comprises copper sheathing 1 and principal arm hinge ear 2.Described copper sheathing 1 loads in the earhole of principal arm hinge ear 2, the assembling fitting surface that copper sheathing and corresponding principal arm cut with scissors ear earhole is joined and bores at least one tapped hole 3, cut with scissors with principal arm inside ear 2 earhole outside described copper sheathing 1 and respectively account for half tapped hole, outside copper sheathing 1, partial thread hole and corresponding principal arm cut with scissors partial thread hole inside ear earhole and form a complete thread hole 3, and attachment screw 5 is installed, the copper sheathing 1 made is relative fixing with principal arm hinge ear 2.In order to further fix the relative position of copper sheathing 1 and principal arm hinge ear 2, the quantity of described tapped hole 3 according to circumstances can use several, as 2,3 can, the corresponding screw of each tapped hole 3.
Described copper sheathing 1 inside has lubrication channel.
Copper sheathing 1 and principal arm cut with scissors ear 2 and coordinate, and cut with scissors ear fitting surface and have tapped hole, and install attachment screw at copper sheathing and principal arm, can effectively prevent copper sheathing relative to cutting with scissors rotating of ear.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope of the utility model request protection.
Claims (4)
