Definitions
- the object of the invention is a friction protector for a rubber drive wheel, which includes slip-stops set on the surface of the circumference, circumference supports providing radial support on either side of the drive wheel, the slip-stops and circum ⁇ ference supports being connected by attachment chains.
- Rubber drive wheels are in general use in the transfer of long objects such as logs and similar, for example in the felling grab of timber-harvesters.
- Several species of trees have, during their growth, a stage when the bark is easily detached, the so-called bast time. It is then difficult for harvesters to handle timber, as the drive wheels tend to slip during operations.
- rubber drive wheels have good properties when com ⁇ pared to metal drive wheels, but in some special types of forest very hard, dry branches form on the trees, which cause great wear on rubber drive wheels.
- protector chains are used in excavators and similar.
- Figure 1 shows the use of a rubber drive wheel friction protec- tor in connection with the opposing drive wheels of a timber harvester.
- Figure 2 shows a partial enlargement of Figure 1.
- Figure 3 shows a form of application of another friction protector.
- Figure 4 shows a form of application of a third friction protector.
- Figure 5 shows a slip-stop from the friction protector in
- the drive wheels are shown as they would appear seen from beneath the harvester, when log 6 is moved as the drive wheels 1 rotate.
- the pressure of the wheels 1 against the log 6 can be adjusted, which at the same time adjusts their gripping power in relation to the log.
- friction protectors which consist of slip- stops 2 covering the entire circumference and are formed from separate plates. Gripping spikes 3 are welded onto them.
- the plate-like slip-stops are connected to one another by means of triangular connector pieces 4, the length of which can be adjusted by turning them to different positions.
- auxiliary slip-stops which prevent the plate-like slip-stops from moving along the circumferential surface of the rubber drive wheel 1.
- This auxiliary slip-stop can also be arranged in other ways on these plate-like slip- stops 2.
- the plate-like slip-stops 2 are connected to the circumference support 7 by means of the connector pieces 4 and chains 5.
- Figure 2 shows schematically the operation of a friction protec ⁇ tor as it presses against the surface of a tree 6 being moved.
- the situation is such that there is great pres- sure from the drive wheels.
- the friction protector can be made to grip the surface of the timber in different ways.
- the pressure is small, the outer grip ⁇ ping spikes 3 of the plate-like slip-stops 2 press very flexibly onto the surface of the timber.
- pressure is increased, when, due to the flexibility of the rubber drive wheel 1, one or two friction plates are pressed in their entirety against the trunk 6.
- FIG. 3 shows another form of application of a friction protec ⁇ tor in accordance with the invention.
- the same reference numbers are used as above.
- the abovementioned triangular connector pieces are not used, instead each plate-like slip-stop 2 is attached to the circumferential support 7 by means of its own attachment chain 5.
- the edges of the slip-stops 2 on the side of the chains 5 are shaped as auxiliary slip-stops 8, which correspond to the aforementioned connector pieces 4 in that they prevent the slip- stops 2 from slipping along the circumference of the rubber drive wheel.
- the friction protector in Figure 4 is similar to that shown in Figure 3.
- the same reference numbers as above are used for operationally similar components.
- the circumference of drive wheel 1 is covered with slip-stops 2, which are secured by means of chains 5 to the circumference support 7.
- the circumferential support 7 consists of U-loops 9 tightened by nuts 10. In this manner it is easy to tighten the slip-stops 2 to the desired pressure.
