Abstract

A protective element for a cross member or shaft housing of a frame in a screening arrangement. The protective element is attachable to the cross member or shaft housing by wrapping the protective element around the cross member or shaft housing and clamping a first portion of the protective element to a second portion of the protective element by at least one clamping device. The protective element has an outwards facing surface, which is wear-resistant to withstand wear from piece goods or particle goods impinging or sliding on the outwards facing surface.

Claims (32)

1. A protective element for a cross member or shaft housing of a frame in a screening arrangement, comprising:

a body portion that is attachable to said cross member or shaft housing by wrapping said body portion around said cross member or shaft housing and clamping a first portion of said body portion to a second portion of said body portion by a first clamping device,

wherein said body portion has an outwards facing surface, which is wear-resistant to withstand wear from piece goods or particle goods impinging or sliding on said surface;

and wherein said body portion includes a second clamping device for clamping said body portion to at least one other protective element.

2. The protective element according to claim 1 , wherein said body portion exhibits a tight fit around said cross member or shaft housing.

3. The protective element according to claim 1 , wherein said protective element comprises elastomeric material.

4. The protective element according to claim 1 , wherein said protective element includes at least one material from the group consisting of:

elastomeric materials, ceramic materials, mineral materials and metal materials.

5. The protective element according to claim 1 , wherein said protective element includes at least two elastomeric materials with different hardness.

6. The protective element according to claim 1 , wherein said protective element comprises polyurethane.

7. The protective element according to claim 1 , wherein said protective element comprises rubber.

8. The protective element according to claim 5 , wherein said protective element further comprises reinforcement material.

9. The protective element according to claim 1 , wherein said outward facing surface of said body portion is provided with at least one wear resistant body.

10. The protective according to claim 9 , wherein said at least one wear resistant body includes at least one material chosen from the group consisting of:

elastomeric materials, ceramic materials, mineral materials and metal materials.

11. The protective element according to claim 1 , wherein said first clamping device includes at least one projection.

12. The protective element according to claim 11 , wherein said at least one projection has a semicircular shape and an undercut so that it has a cross sectional radius that increases with increased distance when moving outwards normal to said outward facing surface.

13. The protective element according to claim 1 , wherein said first clamping device includes at least one hole.

14. The protective element according to claim 1 , wherein said first clamping device includes at least one projection and at least one hole.

15. The protective element according to claim 1 , wherein said first clamping device includes at least one additional clamping device.

16. The protective element according to claim 15 , wherein said at least one additional clamping device includes at least one clamp ring.

17. The protective element according to claim 16 , wherein said at least one clamp ring is an elastic O-ring.

18. The protective element according to claim 15 , wherein said at least one additional clamping device includes at least one pin or bolt.

19. The protective element according to claim 1 , wherein said outward facing surface of said body portion is provided with at least one ridge.

20. A protection for a cross member or shaft housing of a frame in a screening arrangement, wherein said protection is attachable to said cross member or shaft housing by wrapping said protection around said cross member or shaft housing and clamping a first portion of said protection to a second portion of said protection by at least one clamping device, and wherein said protection has an outwards facing surface, which is wear-resistant to withstand wear from piece goods or particle goods impinging or sliding on said surface, wherein said protection consists of a plurality of protective elements comprising:

a body portion that is attachable to said cross member or shaft housing by wrapping said body portion around said cross member or shaft housing and clamping a first portion of said body portion to a second portion of said protective element by a first clamping device,

wherein said body portion has an outwards facing surface, which is wear-resistant to withstand wear from piece goods or particle goods impinging or sliding on said surface;

and wherein said body portion includes a second clamping device for clamping said body portion to at least one other protective element.

21. A screening arrangement including at least one protective element comprising:

a body portion that is attachable to said cross member or shaft housing by wrapping said body portion around said cross member or shaft housing and clamping a first portion of said body portion to a second portion of said protective element by a first clamping device,

wherein said body portion has an outwards facing surface, which is wear-resistant to withstand wear from piece goods or particle goods impinging or sliding on said surface;

and wherein said body portion includes a second clamping device for clamping said body portion to at least one other protective element.
