AI Technical Summary

Problems solved by technology

Excessive bearing clearances shorten bearing life and cause the rotor shaft to tilt, which in turn causes increased wear on the gear meshes that drive the rotor wheels

Embodiment Construction

[0035] exist figure 1 In , an axial section through a hydrodynamic brake with a rotor 1 and a stator 2 can be seen. Therein, a first embodiment of the invention is shown above the axis of rotation of the rotor shaft 1.2 carrying the rotor wheel 1.1 and the transmission gear 7, and a second embodiment is shown below the axis of rotation of the rotor shaft 1.2.

[0036] According to a first embodiment, the rotor wheel 1.1 is arranged axially to the right of the stator wheel 2.1, such that the two wheels 1.1, 2.1 form the torus-shaped working space 3 shown. On the right side of the working space 3, a transmission gear 7 with an oblique meshing gear 7.1 is arranged on the rotor shaft 1.2. The rotor shaft 1 . 2 is supported on both sides, particularly exclusively, by the drive gear 7 via roller bearings 4 , 5 in the form of tapered roller bearings.

[0037] As one can see, when the transmission gear 7 and the inclined meshing gear 7.1 are driven, the force F acting on the rotor s...

Abstract

The invention relates to a hydrodynamic brake with a rotor comprising a rotor blade wheel and with a stator comprising a stator blade wheel, the rotor blade wheel and the stator blade wheel, together, forming a working space that can be filled with a working medium for transmitting driving power from the rotor to the stator. The rotor comprises a rotor shaft, which supports the rotor blade wheel and which is rotationally mounted by means of a bearing having at least two or exactly two antifriction bearings.; The invention is characterized by the following features: the bearing of the rotor shaft comprises a first antifriction bearing that can absorb a predetermined first axial force and further comprises a second antifriction bearing, which is arranged in an axially lateral manner with regard to the first antifriction bearing and which can absorb a predetermined second axial force, the second axial force being greater than the first axial force, and the rotor blade wheel is arranged laterally opposite the stator blade wheel on the same axial side as the first antifriction bearing opposite the second antifriction bearing so that an axial force from the rotor blade wheel toward the stator blade wheel is absorbed by the second antifriction bearing.

Description

technical field [0001] The present invention relates to a hydraulic brake, also known as a hydraulic downhill buffer. In particular, the invention relates to a hydraulic downhill damper whose rotor shaft 5 is supported by two tapered roller bearings. Background technique [0002] Hydraulic brakes are well known in a variety of devices. The hydraulic brake has a stator with a stator impeller and a rotor with a rotor impeller, wherein the rotor impeller and the stator impeller are arranged axially opposite each other so that they form an approximately toroidal working space filled with Use the working medium to transmit the transmission power such as torque from the rotor to the stator, thereby braking the rotor. [0003] The rotor is carried by a rotor shaft. The rotor shaft often also carries a transmission gear at the same time, by means of which the rotor blade is driven in rotational movement. The rotor wheel is usually supported by two tapered roller bearings. [00...
