A conical feed housing (54) surrounds the ribbon.

The whole adapter assembly is removed from the tapered hub by twisting the cap in a second direction which is the same direction as the threads of the threaded lock.

The improved pin includes a tapered or truncated conical-shaped portion (151) which nests in a tapered enclosure (164) when the pins are in the fully extended or locked position.

A conical feed housing (54) surrounds the ribbon.

The bevel gear (22) and the bevel pinion (21) are surrounded by a gearing housing (4) which comprises bearing seats for a bevel gear shaft and a bevel pinion shaft (23).

The shaft (30) includes a tapered portion (31) adapted for engagement with the corresponding tapered portion (135) of the sleeve (130) on one side of a housing (15) when the shaft is inserted into the housing bore.

A gear case (11) supports a motor (10) with a shaft (12) extending into the gear case and provided with a bevel pinion (13).

The main valve seat is formed by a conical seat surface in the housing.

A conical crusher, comprising: an upper housing (20); a tubular axle (30) lodging a supporting rod (40).

In the method, a conical bore (18, 27) is first produced in the housing part (10, 25).

The pressure bearing (10) is composed of a conical arrangement (11, 12) between the case (3) and the axle (8).

A filler part (19) is provided, which is made of a similar material as the housing part (12) and has a cone-shaped lateral surface (21) that fits into the conical bore (18, 27).

A cylindrical guide member is located in the field case housing and a conical guide member is located in the fan baffle.

The output-side bevel gear and the center shaft can be attached to the housing from the radial direction.

The invention relates to a transmission housing for a bevel gear transmission, which housing has a surface that consists of sections and surfaces for add-on pieces.
