Abstract

A formed bearing assembly and a method of making the bearing is provided. The bearing assembly includes a housing and a bearing space formed therein. A slide is disposed within the bearing space and is movable along its longitudinal extent. A bearing is formed in the bearing space between the housing and the slide. The bearing is a solid, formed in the bearing space while in liquid state. At least a portion of the bearing forms the shape of at least a portion of the slide.

Claims

1. A formed slide bearing assembly comprising:

a housing having a longitudinal extent and having a bearing space formed along the longitudinal extent;

a slide disposed within the bearing space of the housing and movable along its longitudinal extent; and

a bearing formed in the bearing space between the housing and the slide;

wherein at least a portion of the bearing forms the contour of at least a portion of the slide which is movable there along; and

wherein the bearing is a solid, formed in the bearing space while in liquid state.

2. The formed slide bearing assembly of claim 1, further comprising an impact member attached to the slide.

3. The formed slide bearing assembly of claim 1, wherein the bearing is configured to receive an impact force external of the housing.

4. The formed slide bearing assembly of claim 1, wherein the bearing is a resilient bearing.

5. The formed slide bearing assembly of claim 1, wherein the housing comprises at least one opening to receive a portion of the bearing when in liquid state to assist securing the bearing to the housing.

6. The formed slide bearing assembly of claim 2, wherein the impact member comprises an impact surface configured to receive an impact force.

7. The formed slide bearing assembly of claim 6, wherein the impact surface is oriented in tandem with at least a portion of the bearing and wherein the bearing is configured to receive the impact force.

8. The formed slide bearing assembly of claim 6, wherein the impact surface is oriented askew to at least a portion of the bearing and wherein the bearing is configured to receive the impact force.

35. The impact assembly of claim 1, wherein the impact member is oriented in tandem with at least a portion of the slide and at least a portion of the bearing wherein the force of the impact is directed to the bearing.

9. A formed slide bearing assembly comprising:

a housing having a longitudinal extent and having a bearing space formed along the longitudinal extent;

a slide disposed within the bearing space of the housing and movable along its longitudinal extent; and

a bearing formed in the bearing space between the housing and the slide;

wherein at least a portion of the bearing forms the contour of at least a portion of the slide which is movable there along; and

wherein the bearing is a resilient material and configured to mitigate effects from an impact force exerted on the slide.

10. The formed slide bearing assembly of claim 9, further comprising an impact member attached to the slide.

11. The formed slide bearing assembly of claim 9, wherein the impact member comprises an impact surface configured to receive an impact force.

12. The formed slide bearing assembly of claim 9, wherein the impact surface is oriented in tandem with at least a portion of the bearing and wherein the bearing is configured to receive the impact force.

13. The formed slide bearing assembly of claim 9, wherein the impact surface is oriented askew to at least a portion of the bearing and wherein the bearing is configured to receive the impact force.

14. A method of making a slide formable bearing assembly comprising:

providing a housing having a bearing space formed therein;

disposing a core in the bearing space;

disposing liquid bearing material in the bearing space between the core and the housing;

allowing solidification of the bearing material;

removing the core exposing a cavity; and

inserting a movable member into the cavity.

15. The method of claim 14, further comprising the steps of attaching the movable member to an actuator.

16. The method of claim 14, further comprising the steps of attaching the housing to a guide assembly.

17. The method of claim 14, further comprising the steps of the guide assembly comprising a base back plate.

18. The method of claim 14, further comprising the steps of attaching a core guide to the core.

19. The method of claim 18, further comprising the steps of providing a space configured to receive the core guide to locate the core in the bearing space.

20. The method of claim 14, further comprising the steps of providing a space in the housing to receive liquid bearing material.

21. The method of claim 14, further comprising the steps of providing a wall in the housing with an opening disposed therethrough to receive bearing material.

22. The method of claim 21, further comprising the steps of sealing the wall during the disposition of the liquid bearing material in the bearing space.

23. The method of claim 14, further comprising the steps of securing the housing to the base during the disposition of the liquid bearing material in the bearing space.

24. The method of claim 14, further comprising the steps of securing the housing to the back plate during the disposition of the liquid bearing material in the bearing space.

25. The method of claim 14, further comprising the steps of coupling the housing to a slide assembly.

26. The method of claim 14, further comprising the steps of coupling the housing to an actuator.

27. The method of claim 14, further comprising the steps of coupling the housing to a cylinder actuator.

28. The method of claim 14, further comprising the steps of coupling the housing to a pneumatic actuator.

29. An impact assembly comprising:

a housing having a longitudinal extent and having a bearing space formed along the longitudinal extent;

a slide disposed within the bearing space of the housing and movable along its longitudinal extent;

a bearing formed in the bearing space between the housing and the slide; and

an impact plate coupled to the slide and configured to receive an impact member;

wherein an impact against the impact member causes the slide to exert a force against the bearing; and

wherein the bearing is configured to absorb the force from the slide.

30. The impact assembly of claim 29, wherein the impact plate is oriented in tandem with at least a portion of the bearing.

31. The impact assembly of claim 29, wherein the impact member is oriented askew to at least a portion of the bearing.

32. The impact assembly of claim 29, wherein the impact member is oriented in tandem with at least a portion of the slide.

33. The impact assembly of claim 32, wherein the impact member is attached to the slide.

34. The impact assembly of claim 33, wherein the impact member is formed integral with the slide.
