Patent number: 4614134Abstract: A gearing unit with planetary gearing stages employs a load sensor and a clutch for disengaging drive through the gearing should the sensor detect overloading. The load sensor is in the form of a stationary pin provided with a strain gauge transducer easily accessible via a bore in a housing. The pin bears on a rotatable component of one of the planetary gearing stages to hold this component stationary during operation and is subjected to force proportional to dynamic loading on the gearing. The clutch serves as a brake to hold a rotatable component of another planetary gearing stage stationary and on release permits this component to rotate to interrupt the drive.Type: GrantFiled: June 20, 1984Date of Patent: September 30, 1986Assignee: Gewerkschaft Eisenhutte WestfaliaInventor: Werner Bohle

Patent number: 4604883Abstract: A mass flow control system for a wire drawing machine wherein wire is drawn through a die by a rotating block driven by a variable speed motor. The thus drawn wire is accumulated as a plurality of windings on the block before being removed therefrom via a guide. The guide is arranged on a carrier ring which rotates independently of the block about the axis of block rotation when a difference exists between the rates at which wire is wound onto and removed from the block. The control system includes a motion detector for generating electrical signals representative of the direction and speed of rotation of the carrier ring. Controls associated with the drive motor and responsive to the aforesaid signals adjust the rotational speed of the block in order to reach a steady state condition where wire is being wound onto and removed from the block at the same rate, and the carrier ring remains motionless.Type: GrantFiled: October 17, 1985Date of Patent: August 12, 1986Assignee: Morgan Construction CompanyInventors: William R.

Patent number: 4601218Abstract: A gearing unit with planetary gearing employs a load sensor in the form of a stationary pin provided with a strain gauge transducer easily accessible via a bore in its casing. A brake with respective plate carriers is associated with the planetary gearing. One of these carriers is held stationary with the aid of the load sensor while the other of the carriers meshes via teeth with a rotatable component of the gearing. During operation the carriers lock together to hold the component of the planetary gearing stationary to permit drive to be transmitted. The load sensor is then subjected to force proportional to the dynamic loading on the gearing and brake. In the event of overloading the carriers are disengaged by hydraulic force in response to a signal from the sensor to permit the planetary gearing component to rotate and thus interrupts the drive.Type: GrantFiled: June 20, 1984Date of Patent: July 22, 1986Assignee: Gewerkschaft Eisenhutte WestfaliaInventor: Werner Bohle
