A regenerative energy system comprises a power source driving a motor that rotates a drive gear about an axis, the drive gear rotating a driven gear about an axis. The drive and driven gears each comprise radially extending teeth projecting from respective gear peripheries, the teeth meshing when the drive gear drives the 5 driven gear. Permanent magnets are disposed in at least some of the drive and driven gear teeth such that the magnetic poles of the drive gear teeth repel the poles of the driven gear teeth. When magnetic repulsive forces between the drive and driven gear teeth are overcome, the drive gear and driven gear teeth can engage one another. A coil is located in proximity to the permanent magnets. The 0 coil can form part of a solenoid. Electrical current is generated in the coil by a movement of the permanent magnets relative to the coil.

A drive includes an electric motor, having a rotor shaft rotatably mounted in a motor housing by bearing(s), and a transmission, having a transmission housing including a housing part and a cover part connected together. A bayonet guide region is arranged on, and projects into a recess of, the housing part. An adapter flange is connected to the motor housing in a torsion-resistant manner and includes a lug region engageable behind the bayonet guide region. The recess is restricted in the circumferential direction by a holding fin provided on the housing part, extending from a bearing receptacle of the bearing of the input shaft of the transmission in the radial direction and is restricted counter to the circumferential direction by a further holding fin provided on the housing part, extending from a bearing receptacle of the bearing of the input shaft in the radial direction.

A waterproof structure for a speed reducer according to one aspect of the disclosure includes: a speed reducer for decelerating a rotational driving force of an electric motor and transmitting the decelerated rotational driving force to a rotationally driven portion; a motor flange housing the speed reducer; a cover externally covering the speed reducer in a liquid-tight manner; and a holding plate and a first fixing bolt provided on an inner peripheral side of the cover to fix the cover to the motor flange.

A motor-gearbox assembly includes a housing, a motor, and a gearbox. The housing includes a first alignment mechanism and a second alignment mechanism. The first alignment mechanism is at a first end of the housing and the second alignment mechanism is at a second end of the housing. The motor is mechanically positioned within the housing in accordance with the first alignment mechanism. The gearbox is mechanically positioned within the housing in accordance with the second alignment mechanisms to mechanically couple to the motor.

A shaft and sprocket assembly having an elongate shaft, a sprocket wheel and at least one bracket member. The sprocket wheel encircles and engages the shaft wherein torque is transferrable between the shaft and the sprocket wheel. The sprocket wheel includes radially outwardly extending teeth and is formed by a plurality of sprocket members. Each of the sprocket members defines an angular portion of the sprocket wheel less than 360 degrees. The bracket member detachably secures the individual plurality of sprocket members together thereby allowing the sprocket members to be easily removed from and installed on the shaft. The bracket member is positioned such that no torque is directly transferred from the shaft to the bracket member. The shaft and sprocket assembly can be used in a variety of applications including in the feederhouse of an agricultural combine.

A motor-gearbox assembly includes a housing, a motor, and a gearbox. The housing includes a first alignment mechanism and a second alignment mechanism. The first alignment mechanism is at a first end of the housing and the second alignment mechanism is at a second end of the housing. The motor is mechanically positioned within the housing in accordance with the first alignment mechanism. The gearbox is mechanically positioned within the housing in accordance with the second alignment mechanisms to mechanically couple to the motor.

A geared motor series includes several motors with different dimensions, which respectively have a motor shaft with a receiving bore on the free end thereof. The nominal outer diameters of the motor shafts of the individual motor dimensions are different from each other. At least one plug-in pinion having a pinion journal is provided with a nominal outer diameter corresponding to the nominal diameter of one of the receiving bores, such that the push-in pinion is fixable to the corresponding motor shaft using a press assembly. The nominal diameter of a receiving bore of a motor shaft of a motor of a first motor dimension corresponds to the nominal diameter of a receiving bore of a motor shaft of a motor of at least one other motor dimension, such that the at least one push-in pinion is fixable to motor shafts of motors having different dimensions using a press assembly.

The transmission holder according to the invention for a roller press has a two-part structure with a transmission part which is connected to the transmission and a separate torque supporting part which is to be connected to the machine base frame or foundation. Transmission and torque supporting part of the transmission holder can be detachably connected to one another, preferably by means of a screw or bolt connection. In one embodiment this connection has two screws or bolts. Advantageously the dismantling or assembly of the rollers can thus be accomplished significantly more simply than according to the prior art since merely the screw or bolt connection between transmission and transmission holder of the transmission holder must be released. Advantageously significantly fewer screws/bolts need to be released for dismantling the transmission which in addition are more readily accessible and have a significantly greater distance from one another than according to the prior art. In addition, no unilateral gravitation forces act after dismantling as a result of the symmetrical transmission part. Likewise the tightening torque of the screws/bolts advantageously does not play a very important role. As a further advantage the transmission holder according to the invention can be manufactured simply and cost-effectively. As a result of the compact shape of the transmission part, advantageously low moulding and manufacturing costs are also incurred.

A bevel gear drive includes an input shaft which includes an input bevel gear and has an input interface at one shaft end thereof. The input shaft is arranged vertically in operation and supported by a bearing at a side of the input bevel gear facing away from the input interface. An output shaft includes an output bevel gear in direct meshing engagement with the input bevel gear, with the output shaft being overhung-mounted and having an output interface at one shaft end thereof which faces away from the output bevel gear. Both, the input shaft and the output shaft are mounted in a drive housing.

A transmission housing includes a profile body configured to enclose transmission components, two side walls configured to enclose the transmission components in the profile body, and a hub rail inserted into a recess of one of the two side walls and fastened to the one of the two side walls. The hub rail includes at least two hubs and is defined by a hub width which is higher than a wall thickness of each of the two side walls. The profile body, the two side walls and the hub rail are each configured without joints in a radial direction of the at least two hubs in order to prevent radial insertion of a one of the transmission components into the hubs.
