摘要:
The invention relates to a seal arrangement for sealing a radial gap between an inner first component (8) and an outer second component (15) which can be rotated in relation to each other, the first component (8) being rotatable about an axis of rotation and the second component (15) being arranged coaxially to the first component (8). The seal arrangement comprises: a dynamic seal part (14) connected to the first component (8); a static seal part (15) connected to the second component (15); a first labyrinth seal (1) formed by a gap between a first section of opposing surfaces of the dynamic seal part (14) and the static seal part (15); and a leaf seal (2) which is radially arranged inside the first labyrinth seal (1). The invention is characterised in that the seal arrangement comprises a dust protection cover (3) connected to the second component (15), which is arranged radially outside the first labyrinth seal (1).

A gearmotor assembly includes a housing, a rotatable shaft, a bearing, a retaining member, and a seal. The housing defines a gear chamber configured to contain a lubricant. The bearing rotatably supports the shaft. The bearing is disposed between the housing and the shaft. The retaining member at least in part restricts axial shifting of the bearing. The retaining member presents a plurality of retaining member threads. The housing defines a plurality of housing threads threadably engaging the retaining member threads. The retaining member and the housing cooperatively at least in part define an interface. The interface includes a threaded portion and an additional portion. The threaded portion is cooperatively defined by the retaining member threads and the housing threads. The additional portion is fluidly interconnected to the threaded portion. The seal is disposed along the interface to prevent lubricant escaping the gear chamber past the interface

There is described a vehicle chassis arrangement, preferably for use in an agricultural tractor. The chassis has two frame elements and a differential housing, where the ends of the frame elements are connected to the side of the differential housing facing the rear of the vehicle. A tank cover is attached adjacent to that side of the differential housing, to define a fluid storage tank between the tank cover and the surface of the differential housing.

A worm drive power tool includes a driveshaft, a worm, a seal member, and a shield. The driveshaft is configured to rotate about an axis of rotation. The worm is configured for rotation with the driveshaft. The seal member includes an inner seal defining a shaft opening through which the driveshaft extends. The inner seal extends radially away from the axis of rotation no more than a first distance. The shield is mounted on the driveshaft between the worm and the seal member. The shield extends radially away from the axis of rotation for at least a second distance that is equal to or greater than the first distance.
