Abstract: A drive train protection system includes an input pulley providing rotary movement to an implement drive gearbox, at least one sensor, and at least one clutch selectively engagable to provide rotary movement to the input pulley from the driver. The sensor is disposed to sense the rotation of an annular toothed surface of the input pulley to monitor input pulley speed and provide a signal indicative of the speed. The clutch is disengagable to disengage the input pulley from the driver in response to the signal indicative of the speed of the input pulley.

Abstract: A method of protecting a drive train from sudden shocks in a machine having a rotatably-mounted implement selectively couplable to a driver by the drive train includes sensing the movement of teeth of an annular toothed surface of the input pulley to monitor the rotational speed of the input pulley, and disengaging the clutch if a programmable controller identifies at least one of a rapid deceleration of a speed of the input pulley, and a difference between the speed of the input pulley, and a calculated speed provided to the input pulley by the input belt from the driver.

Abstract: A tool mounting block is disclosed for use with a milling drum. The tool mounting block may have a flighting portion with a base surface configured to engage an outer cylindrical surface of the milling drum, and a mounting portion integrally formed with the flighting portion at a location opposite the base surface. The mounting portion may be configured to receive a separate tool holder. The tool mounting block may further have at least one locating feature integrally formed with the flighting and mounting portions. The at least one locating feature may be configured to interlock with at least one locating feature of an adjacent tool mounting block.

Abstract: A tool holder is disclosed for use with a milling drum. The tool holder may have a generally cylindrical body defining a first end configured to be received within a tool mounting block of the milling drum, and a second end configured to receive a cutting bit. The tool holder may also have a flange located between the first end and the second end, and a first blind bore initiating at the second end and stopping at the flange such that the generally cylindrical body is substantially solid at the flange. The tool holder may further have at least one sloped surface located at a side of the flange facing the first end of the generally cylindrical body.

Abstract: A chamber for a milling machine includes a milling rotor rotatably mounted transversely on the chamber. The chamber also includes a side plate mounted on the chamber, adjacent to the milling rotor, in a substantially vertical position. The side plate includes a side plate support. The chamber further includes a rotor bearing coupled with the milling rotor and a bearing support configured to receive the rotor bearing. The chamber also includes at least one fastening element to removably couple the bearing support with the side plate support and the rotor bearing.
