摘要:
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 wails. 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.

A modular transmission system selectively coupled to an electric motor arranged on a vehicle according to a first example of the present disclosure includes a front housing, a first rear housing and a second rear housing. The front housing has a transmission motor mount and at least one transmission chassis mount. The transmission motor mount is configured to mount the front housing relative to the electric motor. The first rear housing has a first gear set. The first rear housing is configured to selectively couple to the front housing to provide first gear ratios in the first modular transmission configuration. The second rear housing has a second gear set. The second rear housing is configured to selectively couple to the front housing to provide second gear ratios in the second modular transmission configuration.

Disclosed, is a drive (101) for a sedimentation tank (1000) comprising a main ring gear (160) operatively connected to a cage (150) via a web portion (152). A bearing transfer ring (170) is provided to the web portion (152) such that a gap (172) is provided between the bearing transfer ring (170) and the main ring gear (160). The bearing transfer ring (170) is connected to a first bearing race (144) which communicates with a second bearing race (142) that is fastened to a base portion (136) of the drive (101). Torque (T) is delivered to the cage (150) to turn a rake assembly (1002). The gap (172) provides clearance for deflections, distortions, or deformations of the main ring gear (160) caused by bending stresses (B) in the main ring gear (160) may. The bearing transfer ring (170) absorbs stresses imparted to the main ring gear (160) and prevents fasteners (188) connected to stiff bearing races (144) from shearing. Also disclosed is a retrofit kit for a sedimentation tank drive, a sedimentation tank (1000) having a drive (101) according to the above description, and a method of thickening/clarifying slurry (1008) utilizing a drive (101) according to the above description.

The invention relates to a mobile apparatus and a method for concrete production, comprising a cooling apparatus for cooling bulk material, in particular aggregates for concrete production. The cooling apparatus (100) comprises a bulk material hopper (110), a wetting apparatus (120) and an air supply apparatus (130). The cooling apparatus has a bulk material feeder (140) for feeding bulk material into the bulk material hopper via a bulk material feeder path (141), the bulk material feeder and the wetting apparatus being adapted and disposed in such a way that bulk material to be fed comes into contact on at least one part of the bulk material feeder path with water that is being discharged from the wetting apparatus.

A method of retaining and sealing a cover (1) to a housing (2) of a machine includes applying a fluent adhesive material (4) to one or both of the surfaces of the cover and housing which confront one another when the housing and cover are in an assembled condition, assembling the cover to the housing such that the fluent adhesive material is interposed between the cover and the housing over at least part of their confronting surfaces, applying holding elements (5) to the cover and the housing with the adhesive material interposed therebetween to retain them in their relative positions and then effecting an increase in the mechanical strength of the adhesive material sufficient to retain the cover in position on the housing in normal operation of the machine.
摘要:
A variable speed belt drive of the type having a pair of shiftable discs received on respective input and output shafts with a drive belt entrained thereabout further includes a cooperating housing backbone and support bracket. The housing backbone supports one axial end of the output shaft, and supports the support bracket, which extends through the loop of the drive belt to support the opposite end of the output shaft. The straddle support arrangement permits use of a nonload bearing housing cover and permits the performance of maintenance procedures for the drive belt and input shaft without disengaging alignment and support of the output shaft. One end of the input shaft is supported by the housing and the opposite end is supported with a thrust bearing which is received in a pivot mounted shifting yoke. The yoke cooperates with a member which is axially moved along a shifting screw, to transmit axial shifting force through the thrust bearing to the input shaft so as to change speeds for the variable belt drive. The output shaft support bracket cooperates with the housing to support the shifting screw. The body of the housing serves an alignment function for the fixed constant speed disc of the input shaft. Mounting the support bracket automatically aligns discs on the output shaft per snap rings received in predetermined slots on such shaft for axially situating bearings supporting the output shaft.
