Roller bearing having a brake device
First Claim
1. A rolling bearing having a braking device, comprising:
- an outer hearing ring and an inner bearing ring, between which rolling bodies are in rolling motion on associated raceways,an electromagnet having one of the bearing rings as soft iron core and a coil which encloses the former,a ferromagnetic armature plate connected to the one of the bearing rings, the armature plate being pressed in a direction of a pressure plate connected to the other of the bearing rings to achieve a braking effect, the armature plate being pulled away from said pressure plate in response to actuation of said coil to cancel the braking effect, wherein the pressure plate is of annular design and is received via a thread by an associated thread of the other of the bearing rings, andat least one disk is arranged between the armature plate and the pressure plate, the at least one disk being operatively connected on both sides to brake linings and connected for rotation with the one of the bearing rings or the other of the bearing rings via locating pins which are configured separately.

Abstract
A roller bearing, which has a brake device made of outer and inner bearing rings, between which rollers roll on corresponding rings, a displaceable braking element connected to one of the bearing rings pressed against an associated opposite surface connected to the other bearing ring to generate a braking effect due to a frictional fit, which can be neutralized by an electromagnet. The electromagnet is made of one of the hearing rings as a soft iron core, and a coil encompassing the ring. A ferromagnetic armature plate is connected to one of the bearing rings and is pressed towards a pressure plate, which is connected to the other bearing ring. At least one disc is disposed between the armature plate and pressure plate. The disc is operationally connected to brake linings on both sides, and each have a form-fit connection to one of the bearing rings by guide pins.
