An installation piece for supporting a roller in a roller stand of a roller frame. The installation piece includes a main bore for receiving a journal of the roller, an inlet for a lubricant, an outlet for the lubricant, and a pump device for pumping the lubricant leaving the installation piece through the outlet. The pump device has a housing, an inlet channel, and an outlet channel. The inlet channel communicates with the inlet and the outlet channel communicates with the outlet for the flow of the lubricant. The pump device is driven by the flow of the lubricant in the inlet. The housing of the pump device is equipped with a screw pump and a turbine, which is driven by the pressurized inflowing lubricant, in the inlet channel for driving the screw pump.

An articulated spindle () which is arranged in particular in a drive of a rolling mill, comprises a coupling sleeve for establishing a connection to an articulated head, or an articulated head () for establishing a connection to a coupling sleeve (), wherein the tongue () of the coupling sleeve () engages with a cylindrical opening () of the articulated head () that is located transverse to the rotational axis. A sliding block () is arranged between the articulated head and the tongue (), said block being formed by two sliding bodies (), which have rotational body contours () in two portions, said sliding bodies being arranged rotatably in a rotational body-shaped recess () adjusted to the shape of the sliding bodies () such that they can perform a pivoting motion in the articulated head (). The articulated spindle () is characterized in that the rotational body contours () are designed to be concave or convex and the recess () is designed to be accordingly convex or concave.

The invention relates to a converter gearing, comprising a gear rim (), which is connected to the pivoting axis () of a converter box, said gear rim being engaged with at least one drive pinion () of the converter gearing () and at least one locking device, which can be pivoted to engage with and be disengaged from the toothed gearing of the gear rim, () in the form of a locking arm () that is positioned on a horizontal shaft () and configured with toothed gearing (). The aim of the invention is to improve said locking device. To achieve this, the shaft () of the locking arm () is mounted in at least one terminal bearing (') and the locking arm () can be engaged with and disengaged from the toothed gearing of the gear rim () in a non-positive manner, preferably by means of active force elements (14, 14&#x2032;) in its end regions. In addition, the shaft () of the locking arm () is mounted in the housing of the converter gearing () by means of two eccentric bushes (), which rotate freely within one another, at each of its ends. The mounting is configured in such a way, that by the independent rotation of the same, an ideal mutual engagement position of the two interacting toothed gearing regions of the locking device () and the gear rim () can be set.
