(57) Abstract:

The invention relates to the field of repair of armored vehicles and armament in the field of military repair services. The method reduces the time and effort, save material resources. The inventive before vipresume with three wypracowania bolts outer cone side due to the efforts of the pressure of the ice. To do this, in the cavity formed by wrapped in the shaft side of the transmission tube and a cover with rubber seal, bogatoi to the outer cone of the three mounting bolts through the filling tube is filled with water. Then freeze the water by feeding liquid nitrogen from a cylinder. 1 Il.

The invention relates to the field of repair of armored vehicles and armament in the field of military repair authorities.

The most loaded element chassis tanks is a leading wheel, transmitting torque from the transmission to the tracked mover. When interacting with caterpillar wear crowns wheels. During maintenance N 1 and 2, when the production of tanks for storage and after fording provides Chi graphite grease, sealing the outer cone putty LPC.

Due to lack of maintenance materials, poor funding maintenance is delayed. Due to corrosion the most time-consuming operation when removing the drive wheel is supressive outer cone.

There is a method of removing a cone drive wheel of the tank (See. Instructions for use single sets of universal fixtures and special keys with military repair of armored vehicles and armament. - M.: Voenizdat, 1985. C. 64 - prototype).

He is loosening the tube drive wheel, ipressive outer cone with three wypracowania bolts and wedges which are driven into the slot of the cone.

When you try to compress thus the cone is often twisted body wypracowania bolts flush with the surface of the cone, which significantly complicates the work. To reduce the duration of the removal of the drive wheel when ipressive cone use two sledge hammers to impact on the hub of the drive wheel. If the cone is not vypressovyvaetsya, then tear the leading wheel of the rope together with the cone using a different tank, and remonter is orogovenia cut the hub of the drive wheel with the cone, there is a risk of damaging the shaft side of the transmission.

Thus, the existing method of removing the outer cone of the drive wheel tank unreliable, uneconomical, as it requires in the event of disruption wypracowania bolts raise additional funds.

The task of the invention is to increase the capacity of repair organs, reducing the time and labor saving of material resources when ipressive outer cone of the leading wheels of the tank.

The invention is illustrated in the drawing, where

1 - drive wheel; 2 - cone; 3 - wypracowanie bolts 175.95.118; 4 - water (ice); 5 - gas tube; 6 - shaft side gear; 7 - tube turnkey; 8 - cover; 9 - rubber seal; 10 - bolts; 11 - a container with liquid nitrogen.

This task is achieved by the fact that the tube turns the drive wheel 1, the outer cone 2 vypressovyvaetsya with three wypracowania bolts 3 and additionally due to the efforts of 4 ice formed by the freezing of water 4 poured through the tube 5 into the cavity formed by wrapped in the shaft side of the transmission 6 tube under the key 7 and the cover 8 with a rubber seal 9, bogatoi to cone three mounting boltenia cover l depends on the distance 1 between the lid and the tube under the key the ratio of the densities of waterinand icel: l = l(in/l-1).

As a rule, it is enough to move the cone and its subsequent removal is wypracowanie bolts.

When implementing the inventive method expands the possibilities of repair bodies repair of chassis tanks in the field, decreasing the duration and complexity of removing the drive wheel, reduces the cost of repairs.

The technical result of this method is fade in efforts of removing first due to freezing water, then use wypracowania bolts, it also increases the reliability of the removal of the cone and is not damaged part of the drive wheel.

The method of removing the outer cone of the leading wheels of the tank, including the loosening of the tube drive wheel, vipresume outer cone with three wypracowania bolts, characterized in that the original side of the cone due to the efforts of the pressure of the ice formed by the freezing of water, which is poured through the filling tube into the cavity formed by wrapped in the shaft side of the transmission tube and a cover with rubber seal, bogatoi to cone three credit
