It is designed to be able to move across the supply line P.

Each wedge member 16 for each carrier has spaced apart wedges 17 which are each raised and lowered by a lead screw 18 rotated by a manual shaft 19 via a common drive shaft. each wedge 17
engages with one of the pair of inclined surfaces 2o of the carrier 14. Further, each key 11) 714 is connected to the piston rod 22 of a cylinder 23 by a trunnion 21 between the wedges, and the cylinder 23 is connected to the frame 10 via a trunnion 24. After completing the adjustment of the desired roll gap by manual operation of the wedge, when the piston rod 22 is retracted by the actuation of the cylinder 23, the wedge 17 is forcibly engaged with the inclined surface 20, and the wedge member is Eliminate play.

The carrier 14 is fixed to the gearbox 25,
The gearbox includes an input shaft 26 that is connected via a telescopic shaft 27 to a prime mover 28 consisting of an electric motor. Each gearbox 25 includes a pair of pinions 29a,
29b, and their reduction ratio is 1.25:1 in the illustrated example. The pinion 29a on the input side of the gearbox is connected via a spline connection 30 to a bevel gear/'M star gear mechanism with a high reduction ratio of 72:1 in the illustrated example. In this way, each gearbox 25 as a whole has a high reduction ratio of 90:1 in the illustrated example.

Each carrier 14 has an upwardly facing horizontal surface 31 (FIG. 4), and a vertical flange 33 is integrally erected from this horizontal surface to form a vertical support surface 32. Each carrier 1
A hole 34 is provided in the base 14a of the spline socket 3 as an output element of the gearbox 25.
6 is attached to the hole, and a wheel stopper mechanism 3 is attached to this socket.
The end portion 37 of the drive shaft 38 of No. 9 is splined.

The m width 39 is the horizontal surface 31 of the carrier and the support surface 3.
2 and is freely detachably combined with the carrier.

As described above, due to the engagement of the socket 36 and the end portion 37 that can be freely released, and the sufficient relative movement in the axial direction between the shaft 38 and the socket 36, the spline connection relationship can be freely released. ing.

As shown in FIG. 3, each wheel weighting mechanism 39 includes a trunnion-shaped housing 40 in which two parallel arms 41 are installed horizontally and a vertical member 42.
is placed between these arms, and is connected by bolts 43.
It is connected.

A roller bearing 44 of a normal mechanism is attached to the arm 41, and these bearings are rotatably attached to a roll member 45, and the inner race of the bearing 44 engages with a neck 46 that is integral with the roll member 45. . The roll member 45 has the drive shaft 38 as described above.

The roll member may also be a roll ring fixed in a conventional manner to a shaft on which the roll bearing 44 engages.

The drive shaft 38 of the roll member is connected to the central hole 47 of the roll member.
The torque is transmitted through a key 48 on the top of the drive shaft 38. As a result, the drive@1138 is not subjected to roll loading or distorted.

As shown in FIG. 4, in order to attach each wheel weight mll 139 to the carrier 14, the mechanism is positioned on the upper part of the rear A7 rear 14, and then lowered to lower the lower surface 49 of the lower arm 41. The outer surface 50 of the vertical surface 42 is brought into contact with the upward horizontal support surface 31 and the vertical support surface 32, and then the bolt 51 is screwed from the through hole 52 of the housing 40 into the bolt hole 53 of the carrier 14. Just put it in. When the wheel stopper mechanism 39 is lowered from the fourth position to the assembled position of FIG. 1, the end 37 of the roll member drive shaft 38 is splined to the spline socket 36 of the pinion 29b.
