摘要： An improved clutch and brake unit in combination with a rotatable flywheel, the clutch and brake unit having a housing assembly forming a reservoir chamber around a portion of the drive shaft of a machine and surrounding the clutch and brake unit which permit the housing assembly, clutch and brake unit, and shaft to be removably secured as one unit to the rotatable flywheel. A universal coupling is also disclosed, used in combination with an output shaft of a drive assembly and an extension shaft of a driven assembly, comprising radially outwardly extending flanges at the adjacent ends of each shaft, a mating boss on one shaft matable into a recess in the other shaft to dispose the shafts such that the flanges are adjacent one another, a key inserted in a transversely disposed keyway disposed in part within each shaft, a retainer to hold the shafts together at the flanges and retain the key and securement to secure the retainer to the shafts.

摘要： The invention discloses an improved high-performance drive coupling for a motor, comprising a motor which is connected non-positively to the driven device via a viscous coupling which can be operated selectively by the application of hydraulic pressure. An improved electrically activated control valve serves to control the hydraulic control pressure applied to the coupling and has a control circuit for the actuation of the control valve in order to accelerate the driven device as required. In some applications, a plurality of these drive arrangements can be employed to drive a common device and, in this arrangement, the control devices for the pressurisation of the coupling can be positioned in between in order to achieve a certain progressively delayed pressurisation of the various couplings. The control circuit can also contain a safety correction device which serves to disconnect the coupling in order to decouple the motor from the driven device in the event of abnormal operating conditions.

摘要： There is disclosed herein a clutch-brake unit having a clutch disc pack and a separate brake disc pack which are designed for selective actuation by a single piston arrangement to transmit rotational driving forces from an input shaft to an output shaft via the clutch disc pack and to brake rotation of the ouput shaft via the brake disc pack as desired. An integral oil pump is provided on the input shaft and cooperates with portions of the housing to provide a high volume centrifugal pumping action to continuously circulate oil through passages provided in the housing, input shaft, output shaft and across the clutch and brake disc pads so as to cool them. In one embodiment, the integral oil pump includes a pump chamber separate from the central cavity formed by the housing and also working chambers for the clutch and brake disc packs are separated from the central cavity by annular inner housings. Provisions are also incorporated whereby the oil flow may be directed to external auxiliary apparatus such as oil cooler if desired.

摘要： The brake unit (e.g. for use in controlling draw works of a drilling rig comprises an input shaft (22) which operates to drive a gear pump (96) for circulating oil under pressure over interposed brake discs (136) and plates (140) and through restricted openings (162) during a first direction of rotation such as during lowering of the pipe stands so as both to cool and to lubricate the discs and plates the oil under pressure being operative to move a piston (142) to bring discs and plates into braking relationship upon speed increase to a certain point to provide self-governing speed regulation. During an opposite rotation of the input shaft, such as during raising of the pipe stands, an alternative flowpath is provided by- passing the restricted orifices so as to reduce the drag during raising of the pipe stands. An oil sealing arrangement prevents oil leakage between the input shaft and housing due to the high pressure generated therein, and Figure 7 shows further details of the lubricating system utilizing tanks (212,220).

摘要： 1357061 Friction clutches G M SOMMER CO Inc 29 March 1972 [5 April 1971] 14830/72 Heading F2C In an hydraulically operated multi-disc friction clutch wherein clutch discs 124, 130 are respectively splined to a clutch hub 80 and a drum 136, the clutch hub 80 and drum 136 are detachably secured to driving and driven hubs 40, 42 by bolts 154, 142 to permit transverse removal of the clutch assembly. Removal is facilitated by passing a draw bolt through bores 186 in the hub 80 and into threaded bores 184 in the drum 136 to draw the latter off the hub 42. A pump P supplies pressure liquid through ducts 122, 110, 100 to a clutch actuating cylinder 88 which is axially slidable on a fixed piston 96 and also supplies cooling and lubricating liquid through ducts 160, 164, 169, 170 and orifices 172 to the clutch discs 124, 130. The clutch discs 124 have a steel core with sintered bronze facings that are grooved to produce parallelogram shaped projections.
