  • Ship's Steering Gear Motor Problem Diagnosed Using IR Technology (.pdf)
    The Queen of Saanich Ro-Ro Passenger Ferry experienced a high temperature bearing problem with one of its main steering gear motors. IR analysis showed the non drive end thrust bearing as the source of the heat being generated. It was thought at the time that the bearing was in failure mode
  • Replacing a Mechanical Adjustable Speed Drive with a Variable Speed Drive
    motor is connected to a variable diameter sheave (item A in Figure 1) that transmits power through a belt to another variable diameter sheave (Item B). An internal gearbox can then be used to further reduce speed as necessary. The variable sheave/belt assembly will act as a reduction gear up
  • Direct Drive (DDR) Rotary Table Construction
    Torque motors are also called "frameless" motors. They don't have housings, bearings, or feedback devices. In this sense the motor is a kit and meant to be part of the machine structure. Torque motors are designed as direct drives. They eliminate the need for gearboxes, worm-gear drives, and other
  • No 6 Cement Mill Gearbox Input Pinion Bearing
    ' was on the Drive Motor Bearings. The Bearings had been leaking oil, so new sealing gland was fitted and the only gland packing available was Graphite based so this was used. It was agreed to purchase new bearings for the Input Shaft (24148 C the problematic axial bearing and 23052 C the gear load bearing
  • Gearmotors: Principle of Operation for Engineers
    can be either clockwise or counter clockwise. The direction of rotation of motor gearbox units is generally specified by the gearbox output shaft (drive-side, see DIN EN60034-7, IEC 60050-411). Ratio. A gearbox is characterized by its gear ratio i or its time T. Gear ratio i is the ratio of input
  • The Top 5 Trends In Medical Device Manufacturing In 2019 And Beyond
    are just a few examples of how Johnson Electric's product technology is fueling innovation in the medical device industry: 1) A State of the Art IPS Drive Platform for Insulin Pumps. A coreless, brushless motor technology was the inspiration for Johson Medtech's IPS Miniature Drive Platform
