摘要： A gear pump includes a plurality of gear wheels rotatably retained in a pump housing and that engage in one another for the conveyance of a medium. One of the gear wheels is driven by a pump shaft, which can be coupled to a drive by means of a coupling end. To maintain a uniform conveyance flow, in particular with strongly fluctuating operational pressures, during alternating load states, within a single rotation, a brake ring is disposed on the circumference of the pump shaft, which acts with at least one brake surface on a friction surface of the pump shaft or on a friction surface of the pump housing.

摘要： A gerotor motor including a brake package, and a method for setting the load holding torque of the brake package. The endcap assembly (21) defines a set of internal threads (85) disposed adjacent a brake package piston member (75). An enclosure member (87) defines a spring seat (115) for a set of Belleville washers (105), and defines a set of external threads (88) engaging the internal threads (85). Upon assembly of the motor and brake package, a resistance load is applied to a motor output shaft (43) corresponding to a desired load holding torque. The motor is pressurized sufficiently to rotate the output shaft in opposition to the resistance load. The enclosure member (87) is rotated so that it moves axially in a direction to increase the bias preload on the Belleville washers (105) until the output shaft (43) no longer rotates.

摘要： A fluid pressure motor of the type including a gerotor gear set (15) including a star member (31) which orbits and rotates. The motor includes valving (41) which is disposed forwardly of the gerotor gear set, and an end cap assembly (21;111) disposed rearwardly of the gerotor gear set. The star member (31) defines a central opening (89;127) at the rearward end thereof, which may be defined by a separate insert member (125). Within the end cap assembly (21;111) is a lock piston (75;133) biased by a pair of Belleville washers (85,87;121) toward an engaged position (FIG. 1; FIG. 4) in which a lock portion (79) has its beveled portion (91;135) in engagement with the central opening (89;127) of the star (31), thus preventing any further orbital motion of the star, and serving as a parking lock. The lock piston (75;133) and end cap assembly (21;111) define a pressure chamber (99;119) which may be pressurized by an external signal (95) to move the lock piston to its disengaged position (FIG. 2) in which the beveled portion (91;135) is out of engagement with the central opening (89;127), and the star member (31) is permitted to orbit and rotate in the normal manner.

摘要： A gerotor motor (11) of the type having a spool valve (45) disposed opposite a main drive shaft (35). The motor also includes a set of brake discs (104) in engagement with an extension (45e) of the spool valve (45), and a set of brake discs (106) in engagement with internal splines (108) defined by an end cap (41). A piston (109) operable to engage the brake discs (104,106) is disposed in a chamber defined by the valve housing section (19), disposed adjacent the end cap (41). A valve drive shaft (57) having splines (53) engaging the main drive shaft (35) at its rotating end (33), also has splines (55) engaging the spool valve (45) to transmit the pure rotation of the drive shaft (35) to the spool valve (45). The result is a very compact valve drive and brake arrangement.

摘要： The assembly of a fluid motor with two cubic capacities and of a brake which is coupled thereto, is disclosed. According to the invention, the large cubic capacity of the motor can be selected only when the brake is in its brake-release configuration. One application of the invention is the production of a "braked" motor provided with a relatively small, but operationally reliable brake.

摘要： A rotary hydraulic motor which comprises a brake which is adapted to be applied under the pressure of springs and to restrain the output shaft of the hydromotor when the hydromotor is not pressurized and which is arranged to a supply of hydraulic liquid under pressure to the hydraulic motor. In order to ensure that the hydraulic liquid can be withdrawn from the hydraulic cylinder in a simple manner when the motor has stopped so that the brake can subsequently be applied, the piston of the hydraulic cylinder is provided with an orifice plate or a throttle bore through which the hydraulic liquid can enter a chamber of the hydraulic motor.

摘要： The present disclosure relates to a hydraulic drive having a stationary housing. The hydraulic drive also has a drive shaft that extends through the stationary housing. Furthermore, the hydraulic drive has a hydraulic motor for rotating the drive shaft relative to the stationary housing. Additionally, the hydraulic drive includes a driven hub adapted to be connected to a rotatable driven element. The hydraulic drive also has a coupling/decoupling arrangement that allows the hydraulic drive to be operated in an engaged mode where the drive shaft is coupled to the driven hub in a direct drive arrangement and a disengaged mode where the drive shaft is decoupled from the driven hub. When the hydraulic drive is operated in the engaged mode torque from the drive shaft is transferred to the driven hub causing the driven hub to rotate relative to the stationary housing. When the hydraulic drive is operated in the disengaged mode the driven hub can free wheel relative to the drive shaft.
