A chain guide element having a first guide rail and a second guide rail which is spaced from the first guide rail to guide a moving chain therebetween. On each lateral side of the chain guide element connecting elements connect the two guide rails in spaced relationship to slidably receive a moving chain. First supporting elements are positioned on the laterally arranged connecting elements that connect the first and second guide rails, and second supporting elements are carried by a stationary component to cooperate with the first supporting elements so that the chain guide element is pivotable and is linearly movable relative to the second supporting elements.

A clutch ring gear assembly and method of construction thereof are provided. The assembly has a bearing seat including a flange extending radially outwardly from a central axis. The flange has a plurality of holes spaced circumferentially from one another about the central axis. A ring gear carrier includes a rim extending radially outwardly from the central axis. The rim has a plurality of through openings. Each of the through openings of the rim has an annular boss extending axially away from the rim in generally parallel relation to the central axis. The annular bosses are disposed within the holes and have hollow, annular end portions flared radially outwardly into engagement with the flange of said bearing seat to fixedly attach the ring gear carrier to the bearing seat.

The invention relates to a centrifuge (10), having a drive shaft (12), a rotor (40) mounted on the drive shaft (12) so as to be detachable axially in a removal direction (66), a quick-action closure (54) integrated in the rotor (40) and the drive shaft (12), which closure can be used to secure the rotor (40) relative to the drive shaft (12) in a removal direction (66), an abutment (50, 52) in the drive shaft (12) which is engaged by a locking member (46) of the rotor (40), at least one blocking element (76), which—when activated—fixes the rotor (40) relative to the drive shaft (12) and which acts between the locking member (46) of the rotor (40) and the abutment (50, 52) of the drive shaft (12), which quick-action closure (54) includes a force-transmitting element (58, 72). The invention is characterized in that said blocking element (76) is actively connected to an actuating element (100, 100a) via the force-transmitting element (58, 72), that unlocking the quick-action closure (54) is effected by moving the actuating element (100, 100a), the force-transmitting element (58, 72) and the blocking element (76) relative to the locking member (46) in a direction in parallel to the drive shaft (12), and that during unlocking, the actuating element (100, 100a) is moved toward the drive shaft (12), and during locking, the force-transmitting element (58, 72) and the blocking element (76) on the one side and the locking member (46) on the other side are relatively moved toward each other.

The present invention relates to a mechanical assembly for measuring rpm of a rotating shaft in devices including rotating shaft. Said mechanical assembly comprises an rpm measuring device, which includes a rotating axis for the measurement, a base support which houses and keeps fixed thereto said rpm measuring device, a casing to which said support is fixed and which allows the passage of said rotating shaft, a first rotation drive pulley fixed to the rotating shaft of the rpm measuring device, a second rotation drive pulley fixed to the rotating shaft of the device to which the rpm measurement is to be conducted, the casing being connected to said device, and a belt operatively connected to the first and second drive pulleys, being aligned in the same level. This assembly is totally mechanical, lacking electrical and/or electronic elements, so the risk of generating sparks is not present. The assembly is useful in several industries, especially those in which flammable solvents are used, for example, automotive paint industry.

A system includes an electrically-actuated clutch arranged to selectively connect a shaft to a motor shaft. Ratchets brake the shaft against rotation in either direction when the output is not within either of the predetermined ranges. Thus, when the motor shaft is connected, via the clutch, to the shaft, the ratchets may act as a brake on the motor shaft.

A drive device that drives a detachable unit detachably attached to an image forming apparatus includes a drive coupling, a rotary shaft, a relay member, a contact member, and a compression spring. The drive coupling contacts and separate from a driven coupling of the detachable unit along with movement of the detachable unit. The relay member transmits rotation force of the rotary shaft to the drive coupling to rotate together. The compression spring has an axial end contacting the contact member disposed away from the driven coupling from the relay member and another axial end contacting the relay member. The drive coupling includes an outer circumferential restrictor restricts radial movement of the compression spring. The relay member includes an inner circumferential restrictor restricts radial movement of the compression spring.

A wave spring is disclosed herein that creates hysteresis between two components. The wave spring includes an annular body having a wave-shaped profile, and a plurality of axially extending fingers extending from the annular body. The wave spring is dimensioned to be received in a space between at least two axially opposed hub components.
