Problems solved by technology

Furthermore, the pin neck receptacle in the hub needs to be extensively reworked in order to repair the wear occurring there
This rework in the pin neck housing is also usually done only once, which severely limits the life of the hub with the pin neck housing and requires the procurement of replacement parts

Embodiment Construction

[0023] exist figure 1 shows a rolling mill or a rolling mill drive train in which a roll 1 , also called a work roll, is driven via a cardan shaft 2 with two cardan joints by means of a motor 3 in the form of an electric motor. The cardan shaft 2, in particular embodied as a universal joint shaft, is supported by means of bearings 4 and is mounted via the figure 2 The roller drive connection 5 described in detail in is connected to the roller 1 .

[0024] exist figure 2 It can be seen in the roller transmission connection part 5, which consists of the pin neck 6 of the roller 1 and the universal joint shaft (in figure 2 (not shown in ) or the corresponding hub of the cardan shaft constitutes the pin neck receptacle 7 . The pin neck receptacle 7 has a base body 8 in which an opening 9 is arranged, into which opening the pin neck 6 of the roller 1 is introduced. Two wear linings 10 are inserted opposite each other into the opening 9 in such a way that they delimit the ope...

Abstract

The invention relates to a pin receiving portion (7) for a hub for receiving the pin (6) of a connection unit, in particular of a roller (1), said pin receiving portion (7) having a main part (8) with an opening (9), which is at least partly lined with at least one wear plate (10), for inserting the pin (6). The wear plate (10) has a front surface (10.1) for bearing on the pin (6), said front surface delimiting the opening for the pin (6), and the wear plate (10) has a rear surface (10.2) which faces away from the front surface (10.1) and which rests against a receiving surface (8.1) of the main part (8) at least temporarily. The wear plate (10) has a lower hardness on the wear plate rear surface (10.2) than the receiving surface (8.1) of the main part (8).

Description

technical field [0001] The invention relates to a pin neck receptacle for a hub according to the preamble of claim 1 for receiving a pin neck of a coupling device, in particular a roll, for example a work roll. Background technique [0002] In rolling mills, as the invention relates in certain applications, the drive to the work rolls is established via a roll drive connection, where cardan shafts, especially heavy cardan shafts with a rotational diameter exceeding 550 mm, At the axial end there is a hub with a pin neck receptacle which slides onto the end-side pin pin at the end of the driven roller. Such hubs are also known as impactor hubs. Usually, the roller has a flat pin neck, which generally comprises two oppositely facing flattened circumferential areas for torque transmission, which act on correspondingly flattened areas of the opening of the pin neck receptacle, wherein , The pin neck accommodation is also called the impactor, and the connection with the roll ne...
