Description

Device consisting of bearings and tie rods {ARRANGEMENT CONSISTING OF A BEARING AND A TIE ROD}

The invention relates to an apparatus according to the preamble of claim 1.

In the German patent publication DE 602 10 974 T2 "suspension device of a cab" a combination of bearings and tie rods is known. This combination is used for the purpose of supporting the cab against the body frame.

In this patent publication, the cab is screwed with a bearing fixed to the vehicle body frame by means of a rectangular connecting member, ie a tie rod. The bearing is screwed with the cab cap such that portions of the cab cap are tightly clamped between the two nuts. The nuts are fixed to the rectangular connecting member by screws.

In addition, disc- or plate-type vibration-damping elements are used for the purpose of absorbing load in situations such as accidents. The vibration damping member is likewise connected to a rectangular connecting device and vibrates with the connecting device. Since situations such as accidents occur only once or not much, the vibration damping member is only rarely subjected to abnormal loads.

A disadvantage with known structures is that twisting can occur in the bearing, vibration damping member and / or rectangular connecting member during the assembly process.

In particular, it is considered a disadvantage that a constant torsion in the bearing can be caused. This constant twisting poses a major disadvantage especially when the bearing is designed as an elastomer bearing with a viscoelastic damping action, and when the torsion enters into the load bearing elastomer section.

Torsion can result in reduced bearing life and / or negative variations in bearing usage characteristics depending on the torsion angle.

It is an object of the present invention to provide a device in which a bearing is connected to a support without problems and continuously and stably.

The problem of the present invention described above is solved by the features of claim 1.

The apparatus according to the invention comprises a support, a mass to be disposed and a bearing connected to the mass to be disposed and supported on the support, in which case the mass to be disposed can be moved relative to the support, and A connecting member is provided for connecting the support to the mass to be disposed.

According to the invention, the connecting member consists of a disc-shaped section and a bolt-shaped section formed integrally with each other.

The first manifestation according to the invention is that the bearing must have a connecting member that can be matched to the bearing and act as a tie rod. What is then revealed is that the tie rod, consisting of a disc-shaped section and a bolted section integrally connected with the disc-shaped section, is particularly stable due to its integrity. Furthermore, it is revealed that the bolted section can be accommodated in the support without problems, in which case the disc shaped section can reliably contact the bearing. The support may be arranged in a forced engagement manner on a suitable support surface of the bolted section. In this regard, a device is provided in which a bearing can be continuously and stably connected to a support without problems.

Thus, the problem mentioned in the introduction is solved.

In the connecting member, a through-hole in which the screw is received may be provided, the screw head of the screw abutting the front face of the connecting member. In this case, the connecting member is formed as a tie rod. The through hole is used to fix the tie rod directly to the bearing using screws. The screw can be inserted into the tie rod and secured to the bearing through the tie rod, in which case the screw head abuts the appropriate front face on the tie rod.

Under this background, the thread-end of the screw opposite the screw head can be screwed into the bearing. Thus, the connecting member or tie rod can be fixed without problems by the bearing. The thread end can be tightened into a hydraulic bearing or an elastomer bearing.

In the bearing and connecting member, shear pins extending from the bearing into the connecting member can be accommodated. The shear pins prevent torsion between the connecting member and the bearing or the tie rod and the bearing. These structural features of the device can prevent twisting of the supported elastomer bearing section, especially during the bearing assembly process.

The bolted section may have an annular support surface for the support. Thus, the connecting member can be installed and assembled almost tilt-free by the support.

Bolted sections can have threaded sections. Thus, frictional engagement by threaded connections can occur, which interconnect the threaded sections of the bolted section, the support, the mass to be placed and one or more threaded nuts.

The connection member may be formed with one or more elastomeric stop members. This allows the connecting member to counter the bearing smoothly. In this regard, a gradual stop characteristic can be implemented. Elastomeric stop members may be disposed on opposite sides of the connecting member.

The bearings described herein can be designed as elastomer bearings or hydraulic bearings, which are provided with tie rods of the connecting member type.

The device according to the invention consisting of a bearing and a tie rod can be installed in a motor, a gear, a compressor or a generator.

In particular, the apparatus can be used in equipment for generating energy, ie wind power plants, equipment for extracting, manufacturing or processing raw materials.
