Spring-loaded wheel guiding KVO 40 SE P1, P2

The spring-loaded wheel guiding KVO 40 SE serves for the rolling guiding of transport vessels – skips – on the steel guide rails. It is innovation of the existing wheel guiding of the types KVO 350 and KVO 40. It is manufactured in two versions – P1 and P2, which differ in the execution of the side wheels.

Dynamic impulses called during the run by asperity of the guide rails traction are eliminated with resistance and hysteresis of the rubber rings bunch. The flexible fixation of these forces fundamentally reduces impacts of dynamic impulses on the transport vessel construction and on the working pit equipment. The operation spring-loading follows the fractional characteristics of rubber springs; the characteristics can be modified by the composition of the springs according to needs. The springs hysteresis assures attenuation of the spring-loading counter-motion. After the clearance between the guide rail and the transport vessel is exhausted the transport vessel fixed-guides sit down on the guide rail.

Description: For the transport vessel equipment there are necessary four sets of the wheel guiding placed on the faces of the upper and bottom part of the skip vessel.

The set is formed by three independent mounted units assembled on a baseplate – two swing spring-loaded arms with wheels for side guiding and one swing spring-loaded arm with an axle for front guiding. The spring-loaded arms have the same design. They consist of 2 side frames as fix-parts carrying rods for rubber rings. The side frames are placed through self-lubricating sliding bushings on a tubular axis, that is reposed in split casings welded on the baseplate. The side frame are indented in the back part for the passage through the corner guiding and they are connected with a crossbeam forming together with a screw and nuts a thrust setting construction. The swing spring-loaded part of the arm consists of a drum with forks. In the concentric tubes of the drum there are placed the outside parts of the rubber rings. The forks welded on the drum coat bear the split casings for inserting the guiding wheel axes.

The side wheel P1 consists of a replaceable ring with a rubber back-cloth placed in split discs on ball bearings. The axis is reposed in split casings of the arm.

The side wheel P2 consists of a replaceable rubber tire inserted in a two-part screw-disc placed on cone-bearings on the eccentric axis. One side of the axis is reposed in the tapered socket,
the other one is reposed in the split casing.
