The invention relates to a process of repair equipment, in particular to devices for repair of high pressure hoses hydraulic forestry machines.

The closest analogue is the device for repair of high pressure hoses hydraulic forestry machines containing cylindrical body mounted in the housing matrix, in which evenly spaced around the circumference with the possibility of radial movement posted lobes oblong, two internal surfaces with a metallic clutch repair sleeves, and outer with screw-down mechanism.

A disadvantage of this device is its lack of effectiveness, because it does not provide the result of our pursuit of the coupling end, which reduces the reliability of the coupling sleeve.

The technical result, which directed the inventive device is to increase efficiency by providing the result of our pursuit of the coupling end, which increases the reliability of its connection with the sleeve.

For this purpose, the proposed device for repair of high pressure hydraulic forestry machines, the body is made in the form outside the sm in the form of bolts, wrapped in the outer ring, and each of the bolts associated with the outer surface of the Cam by means of a spherical joint formed by the ball head on the end of the shank of the bolt is installed with a gap in the spherical socket of the Cam, the face surface is limited to the perpendicular axis of the housing to one plane, passing in a different plane, inclined to the axis and communicating with the surface of the corresponding groove of the inner ring, and the angle of inclination of the other specified plane is selected in the range from 5 to 9about.

In Fig.1 shows a device for repair of high pressure hoses hydraulic forestry machines, front view; Fig. 2 is a side view, and Fig.3 the junction of the Cam with the clutch sleeve high pressure, in an enlarged scale.

The device for repair of high pressure hoses hydraulic harvesting machine comprises a cylindrical housing in the form of an outer ring 1, which has a matrix made in the form of the inner ring 2, concentrically mounted in the outer ring. In the grooves of the ring with the possibility of radial movement mounted Cams 3 are oblong in shape. Each Cam his brogna surface of the Cam 5 is connected with the bolt of the adjusting mechanism, wrapped in the outer ring by means of a spherical joint. This hinge is formed ball head 7 of the bolt and the socket 8, made in the Cam 3, in which the head is mounted with a clearance. One end surface of the Cam is limited to the perpendicular axis of the housing plane 9 and related plane 10, which interacts with the surface of the groove of the inner ring 2.

The angle of the plane of the 10 selected within 5-9aboutreasons, the maximum efficiency of the bending end part of the coupling. When the value of angle less 5aboutwill be provided by bending the end part of the coupling. When the value of the angle, the greater the 9aboutincreases the force on the bolt, and the ACC will be before there will be a complete interaction of the inner part of the Cam 3 with the clutch 5.

The other end surface 11 of the Cam perpendicular to the axis of the housing and mounted with a gap b relative to another surface of the groove. Clearances a and b are equal. The rotation of the bolt is at its head 12. Each bolt is located in the same radial plane with the corresponding Cam 3. The inner surface 4 of each of the Cam 3 is made with a curved section 13 for bending the end part of the coupling 5 and the Popper.

Prepared by the sleeve 6 high pressure put on him by the sleeve 5, the nipple and coupling nut is inserted into the middle part of the inner ring 2. Pre-bolts for the head 12 turn on the required value to move the Cam 3 in a position in which the sleeve 6 with the clutch 5 can be freely inserted between the jaws 3. Then manually turn the bolts that their ball heads 7 move the Cams to contact with the clutch 5. After that, putting the head 12 of the bolt force with a torque or a regular wrench, alternately tighten the bolts in diametrically opposite directions. While the Cams 3 press their internal surfaces 4 on the clutch 5, firmly connecting it with the high-pressure hose. At the same time bending the end part of the coupling due to the fact that at the end of the movement of the Cam to its plane 10 slides on the surface of the ring groove 2, which facilitates the movement of the Cam in the axial direction and the effective bending the end part of the clutch, which ends after the selection of the gaps a and b.

Further increasing the strength of the coupling 5 with the sleeve 6 high pressure is achieved by obtaining Galenia HYDRAULIC FORESTRY MACHINES, containing cylindrical body mounted in the housing matrix, in which evenly spaced around the circumference with the possibility of radial movement posted lobes oblong, two internal surfaces with a metallic clutch repair sleeves, and external with external mechanism, wherein the body is made in the form of an outer ring, and the matrix in the form of an inner ring concentrically mounted in the outer ring, and the compression mechanism in the form of bolts screwed into the outer ring, and each of the bolts associated with the outer surface of the Cam by means of a spherical joint formed by the ball head on the end of the shank of the bolt, installed with a gap in the spherical socket of the Cam, the end surface of which is restricted perpendicular to the axis of the housing to one plane, passing in a different plane, inclined to the axis and communicating with the surface of the corresponding groove of the inner ring, and the angle of inclination different plane selected within 5 9o.
