Abstract
Description
State of the art:
[0001] A bolt in mechanical engineering is often a cylindrical element. Its primary function is to absorb static or dynamic forces. A bolt can also be used as an axial guide. Bolts in mechanical engineering are joined to other assemblies using force, form, or material bonding.
[0002] The problems underlying the invention: Point 1
[0003] To reduce manufacturing costs in mechanical and plant engineering, it is advisable to use standardized components. Flange bearing units according to ISO 3228 or ABMA 14 are not suitable as bolt mounts. The ball bearings inside the housings have spherical outer rings, as required by DIN 626-1. This allows the bearing axis to move. Therefore, they cannot absorb radial forces. Point 2
[0004] It is often necessary for a bolt to be radially movable, for example, when it serves as a mount for a tension pulley.
[0005] This requires that the bolt must be designed as a detachable connection. Point 3
[0006] When a bolt is joined to a thin-walled housing, the radial force acting on the bolt can create a bending moment at the joint. This can lead to plastic deformation of the housing.
[0007] This could impair the function of the machine. Problem solving
[0008] The invention involves standardized flange bolts as a supplement to flange bearing units similar to ISO 3228 or ABMA 14. The bolt diameters are based on these standards. The bolt lengths are variable. (Solution Point 1)
[0009] The bolt is connected to the flange in a form-fitting and force-fitting manner.
[0010] The bolt is made of metallic materials
[0011] Depending on the diameter of the bolt, the flange is made of plastic or metallic materials.
[0012] The surface finish is modified to protect the flange bolts from corrosion.
[0013] The locking and securing of the components to be held by the bolt is done, for example, using clamping rings, shaft retaining rings, threaded holes as well as screw connections, split pins, nuts or similar.
[0014] The flange plate is provided with through holes and can be force-fitted to existing machine housings. The through hole can also be threaded, allowing installation from either side. If the housing has elongated holes, the flange bolt can be screwed through them. This allows for movement and locking. (Solution point 2)
[0015] The thickness of the flange plate depends on the bolt diameters and lengths.
[0016] This distributes the resulting torques evenly across the machine housing. Solution (point 3) List of reference symbols 1 bolt 2 flange plate 3 Hole
