Abstract
The moveable roll of a rolling mill is locked in the engaged position by lock means which include a tension shaft. The tension shaft is telescoped through and biased by a compression spring toward the stationary roll. The end of the tension shaft has an eccentric which causes a housing pad to engage arms carrying the bearings of the moveable roll. pg,6
Claims12
In a roller mill having:
- a. a frame,
- b. a stationary roll and
- c. a moveable roll,
- d. each roll having two ends,
- e. a frame bearing mounted to the frame upon each end of the stationary roll,
- f. a moving bearing on each end of the moveable roll, and
- g. an arm pivoted to the frame at each end of the moveable roll having one of said moving bearings mounted thereon;
- the improved structure for locking the arms in an engaged position comprising:
- h. a pair of two ended spring holders, each one having
- i. a clevis end attached to the frame near one of the frame bearings, and
- ii. a nut end,
- j. a two ended helical compression spring in each spring holder,
- k. one end of each spring bearing against the nut end of the spring holder,
- l. a tension shaft having a spring end and a distal end telescoped in each spring,
- m. a spring nut on a spring end of each tension shaft bearing against the other end of each spring,
- n. a pair of lock means for moving and locking the arms in the engaged position,
- o. one of said lock means on a distal end of each tension shaft,
- p. a connecting shaft extending from one lock means to the other, and
- q. a handle on the connecting shaft for rotating the connecting shaft which operates said lock means,
- r. a clearance adjustment nut on the nut end of each of the spring holders bearing against the arm in the engaged position,
- s. said clearance adjustment nut has a bore therethrough, and
- t. said tension shaft extends through said bore in said adjusting nut.
