New to BMG’s range of Tsubaki cam clutches is the BR-HT series, designed for use in inclined conveyors and bucket elevators. These backstop cam clutches, which offer optimised speed over-running and higher torque than conventional cam clutches, prevent reverse rotation of drive shafts, thus avoiding damage to machinery and expensive equipment.
The BR-HT series, which is available in 65 units, with bore sizes from 20 to 320 mm, provides torque capacities from 105 Nm to 366 000 Nm and maximum over-running speeds from 1000 rpm to 3600 rpm.
“These new robust backstop cam clutches are ideal for OEM applications and have a special integrated design with lift-off cams that provide mechanical engagement only when needed and optimised speed overrunning, with no contact between cams and races,” says Carlo Beukes, BMG’s power transmission product manager. “At all other times, the cam clutch rotates freely, with no mechanical contact in the clutch mechanism. The result of this non-contact operation is extended service.”
The high torque capacity of the BR-HT clutch is the result of a design featuring a full complement of cams to provide the maximum number of load transmitting members per given diameter. This means greater torque capacity size-for-size compared to other types of one-way clutches.
The simple design, in which the cam clutch mechanism is incorporated in a cage between standard dimension inner and outer bearing races, allows the cam clutch to be easily integrated into a wide range of mechanical systems. The facility for this type of mounting is further enhanced by a keyway that simplifies installation by ensuring positive location and fixing of the clutches onto shafts. With the outer race of the clutch anchored to a stationary member, the inner race can overrun freely in one direction of rotation, even at high speed. Reverse rotation is instantaneously prevented by the automatic engagement of the clutch.
South Africa’s Mine Health and Safety Act states that the installation of incline conveyor belts must include the fitting and use of one or more devices to prevent run-back or run-on which could cause injury through materials or minerals falling from a conveyor belt. Tsubaki back stop cam clutches – designed for safety in high or low speed applications – meet the requirements of this legislation.
BMG’s technical team advises on the selection of the correct cam clutch for each application and the appropriate installation and usage for optimum performance and improved safety standards.
