Product Details:
Lovejoy 69790406151 grid coupling hub with a keyway is designed to attach to a shaft on one side and to a grid coupling on the other side, allowing seamless torque transmission between two shafts.
Features:
- It is made of high-quality steel that helps to resist bending, cracking and other forms of damage that can occur during the operation.
- The grid-style design dampens vibration and cushions shock loads that otherwise could damage both the driving and driven equipment.
- It has a tapered grid spring that absorbs impact by spreading the energy evenly over the full length of the grid spring while protecting the connected equipment from damage.
Frequently Asked Questions:
Q. What is the use of Lovejoy grid coupling?
A. A grid coupling is designed to connect two rotating shafts and transmit torque between them while accommodating any misalignment that occurs during application.
Q. What is the benefit of a curved hub tooth profile?
A. A curved hub tooth profile in a Lovejoy hub creates progressive contact with the flexible grid spring as the application torque increases, providing efficient transmission of power in properly aligned couplings.
Q. What is a keyway?
A. A keyway is a groove or slot cut into a shaft or other parts of a machine to accept a key. The keyway also prevents using the wrong key in the wrong slot.
