A crank-operated packer mechanism includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings. The connection further includes a locking feature for locking the connection, such as a locking nut screwed onto a threaded outer end of the crank pins when inserted into the opening. Fixing of rotary bearings onto the crank pins is done by a fixing nut which at the same time serves as a disassembling aid for the spline connection. The crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced about its central rotation axis. Also a baler including the aforementioned packer mechanism.

A method for spin set bearing setting verification in a preload state on a shaft. An inertia wheel may be disposed on the shaft. The inertia wheel or the shaft is rotated. A first rotational speed is measured at a first time. The inertia wheel may decelerate over time to achieve a second rotational speed measured at a second time. The second speed is less than first speed. The change in time between the first time and the second time is measured. The bearing setting may be adjusted if the change in time is outside a predetermined time range. The bearing setting may remain unchanged if the change in time is within a predetermined time range.

Aspects hereof relate to a control system for a terrain working vehicle having an operator protection apparatus. In some aspects, the control system instructs and ceases an actuation of the operator protection apparatus to and between a raised position and a lowered position.

An integral hammer (M) designed for the assembly of a sowing disc (D) which is fixed with the bolts (22) and nuts (23) is described. It stands out due to the fact that it includes machining on its internal face of a first raceway (10) and a second raceway (11) for the direct assembly of a first conical roller (12) and a second conical roller (13), thus eliminating the need to incorporate the cups that make up conventional bearings from the outset. For the assembly of said first conical roller (12) and second conical roller (13), the first internal cone (14) and a second internal cone (15) that define the inner bearing rings are used. In this way, the integral hammer works as a single unit that includes the aforementioned first internal cone (14) and a second internal cone (15) with their respective first cage (16) and second cage (17) constituting the hammer-bearing set.

An axle assembly includes a spindle to receive a drive shaft having a rotational input about an axis and a wheel hub rotatably supported by at least one roller bearing disposed on the spindle. A tire inflation system defines a spindle gas passage to route pressurized gas from an onboard source through the spindle. The tire inflation system includes a seal chamber between the spindle and wheel hub to transfer gas from the spindle to the wheel hub, and a hub gas passage in fluid communication with the seal chamber is arranged to route the pressurized gas to a tire. A lubrication system having a reservoir is located axially outboard of the seal chamber and at least one hub lubricant passage routes lubricant between the reservoir to a roller bearing located axially inboard of the seal chamber. The hub lubricant passage routes lubricant radially outward of the seal chamber.

An apparatus includes a housing; a spherical bearing disposed within the housing; a shaft disposed in part beneath the housing and penetrating a portion of the spherical bearing; a bellow circumscribing a lower portion of the housing and providing an interface between the spherical bearing and the shaft; and a cover adjacent a lower end of the bellow and having a circumferential groove configured to enable rotational movement of the bellow, the cover extending to and circumferentially surrounding a portion of the shaft to seal the shaft.

A joint element provided with a swing dampener element and comprising a first joint part, a second joint part, and a swing dampener brake. The second joint part comprises a second end part which is detachably fixed to a first end part of the second joint part by a joint part coupling which is adapted to allow the second end part to be moved in an axial direction to a detached position in relation to the first end part, the detached position allowing replacement of active components of the swing dampener brake while the first end part remains bearing-mounted to the first joint part, the active components of the swing dampener brake comprising at least one first brake disc member and at least one second brake disc member.

The invention relates to a linking device for coupling working equipment, such as a head for harvesting trees, to the end of a crane boom on a working machine, said end comprising crane ears, wherein the linking device comprises a linking device body that supports a first rotation shaft defining a first rotation axis and a second rotation shaft defining a second rotation axis that runs substantially transverse to the first rotation axis, wherein the linking device is intended to be suspended by the first rotation shaft between the crane ears for free rotation of the linking device around the first rotation axis on the crane boom, wherein the linking device comprises first braking means for braking the rotational movement of the linking device around the first rotation axis, wherein the first braking means are arranged to move at least one of the crane ears towards the other to clamp the linking device body between the crane ears.

An axle assembly includes a spindle to receive a drive shaft having a rotational input about an axis and a wheel hub rotatably supported by at least one roller bearing disposed on the spindle. A tire inflation system defines a spindle gas passage to route pressurized gas from an onboard source through the spindle. The tire inflation system includes a seal chamber between the spindle and wheel hub to transfer gas from the spindle to the wheel hub, and a hub gas passage in fluid communication with the seal chamber is arranged to route the pressurized gas to a tire. A lubrication system having a reservoir is located axially outboard of the seal chamber and at least one hub lubricant passage routes lubricant between the reservoir to a roller bearing located axially inboard of the seal chamber. The hub lubricant passage routes lubricant radially outward of the seal chamber.

A hub bearing assembly for the rotatable mounting of a soil cultivating disc (D) on a support shaft (A) of an agricultural machine, the assembly being provided with a hub bearing unit which in turn is provided with a flanged outer ring carrying two integral outer raceways for respective rows of rolling bodies, a flange fixed to the flanged outer ring for mounting a disc (D), and, for each outer raceway, an inner ring axially adjacent to the other inner ring, both of which can be engaged by the support shaft (A); and a sealing device mounted on a side of the hub bearing assembly opposite the side of the flange, composed of a first sealing stage and a second sealing stage arranged sequentially along the support shaft (A) and housed in respective seats formed directly in the flanged outer ring.
