    摘要： Transmission housing (1) having a body (2) formed by two shells (2A, 2B) and comprising a rotary input shaft (4) and an output shaft (5), the rotary input shaft (4) comprising a driving end (6) and a threaded portion (7) and having mounted on it a rolling-element bearing (8) arranged between the threaded portion (7) and the driving end (6), said housing (1) creating, inside the enclosure (3), a station (12) for receiving the rolling-element bearing (8) and a station (13) for receiving the threaded portion (7). The housing (1) comprises a barrier (14) positioned between said stations (12, 13), this barrier (14) extending around said input shaft (4), creating a through-passage (15) for access for the input shaft (4) from one station (12) to the other (13), this barrier (14) being formed in at least two portions (16, 17), each barrier portion (16, 17) being produced in a single piece with the associated shell (2A, 2B), at least one of the barrier portions (16, 17) being shaped so as to create at least one deflector (161) formed at least partially by an inclined surface having a slope that descends from the body (2) of the housing (1) towards the input shaft (4), when the input shaft (4) is positioned vertically with the rolling-element bearing (8) extending above the threaded portion (7) of the input shaft (4).

    摘要： A sorghum cutting header and a sorghum harvester with large feed volume and multiple reeling pans includes a reeling header, a rod crushing device, and a reciprocating cutter device. The rod crushing device is located under the reeling header. The reeling header includes reeling pans, frame rods, bearing seats, reeling pan shafts, tandem shafts, and tandem shaft bearing seats. The reeling pan shafts are installed in parallel on the frame rod through bearing seats. The adjacent reeling pan shafts are in transmission connection, and at least one reeling pan shaft is in transmission connection with the power device. An inner part of any reeling pan shaft penetrates the tandem shafts. Both ends of the tandem shafts are supported on the frame rods, and one end of the tandem shafts is fixed on the tandem shaft bearing seats. The reeling pans are mounted on any reeling pan shaft.

    摘要： A shifting device for a transmission is disclosed. The shifting device comprises a transmission shaft, a shift gear being mounted thereon, wherein the shift gear is configured with a connecting hub which is axially displaceable relative to the transmission shaft, wherein the connecting hub has an internal toothing in engagement with an external toothing of the transmission shaft, so that the shift gear is drive-connected to the transmission shaft in an axially displaceable manner therewith. A latching device is further provided, the shift gear being axially displaceable thereby into a plurality of latching positions. The latching device comprises a spring-pretensioned setting pin displaceably mounted radially to the transmission shaft and in engagement with a setting shaft rotatably mounted in the transmission shaft, such that the setting shaft and the setting pin can be brought out of an unlocked position into a locked position and vice-versa by rotating the setting shaft.

    摘要： The present invention is directed to a string trimmer having a blower feature incorporated therein. The string trimmer has a cutting head for holding a spool with cutting line. The cutting line is rotated at high speed to cut grass and other vegetation. The cutting head also includes a fan for generating an airflow to act as a blower. The string trimmer can be operated in two modes. In a first mode, both the fan and the spool housing are engaged with the motor so that the rotation of the spool housing performs a cutting operation. In a second mode, the motor engages only the fan to blow air, and the spool housing is disengaged so no cutting operation is performed.
