Abstract:
A method for fabricating an input pinion for an automotive differential that includes: providing a shaft; forging a pinion with a plurality of teeth such that each tooth is formed to at least a near-net size, forming a hole in the pinion, pressing an end of the shaft into the hole in the pinion, and securing the shaft to the pinion.
Abstract:
An axially compact and highly integrated bevel pinion and bearing assembly (A1, A2) wherein a pinion gear (10) is integrated with a first support bearing (B1), and the pinion shaft (12) is integrated with a second support bearing (B2) axially displaced from the first support bearing (B1). With the first support bearing (B1) arranged axially under the pinion gear teeth (11), loads from the pinion gear (10) are transferred primarily through the first support bearing (B1). As a result, the second support bearing (B2) can be reduced in size and brought axially closer to the first support bearing (B1) to reduce the axial length of the pinion and bearing assembly. The integration of the pinion gear (10) with the first and second support bearings (B1, B2) optimizes material utilization and reduces overall weight of the pinion and bearing assembly, leading to a power density improvement.
Abstract:
An oblique contact ball bearing adopted to support a pinion shaft, where a sufficient range of rotation torque is provided for the oblique contact ball bearing to facilitate highly accurate setting, adjustment, and management of preload. To achieve the above, in the oblique contact ball bearing, a rust preventive oil (35) having kinematic viscosity at 20°C of 1 - 30 mm /s is provided at the portions where raceways (11a, 11b, 13a, 13b) of inner and outer rings (11, 13) and balls (17, 18) are in contact with each other. This increases rotation torque of the bearing and preload setting is made in this state. As a result, when a predetermined pressure-contact force (thrust load) is applied to the balls (17, 18) and to the raceways (11a, 11b, 13a, 13b), an oil-less state is relatively easily obtained and only an oil amount necessary for rust prevention stays on the raceways (11a, 11b, 13a, 13b) etc.
Abstract:
Rodamiento de piñón de ataque (6), que comprende una carcasa (2) y dos rodamientos de rodillos cónicos de una hilera (1) que están unidos entre sí por sus aros de rodadura interiores (4, 5) mediante un anillo (3), estando el anillo (3) posicionado entre los extremos de los aros interiores (4, 5) y la superficie periférica del eje del piñón de ataque (6). Gracias a esta disposición del anillo de unión (3) resulta más sencilla la operación y verificación del montaje del conjunto y se facilita un eventual desmontaje al evitar que el anillo pueda romperse al extraer el eje del piñón de ataque (6).
Abstract:
The present invention relates to a device for a parking brake for a forklift truck and a construction equipment vehicle, and more specifically, to a device for a parking brake for a forklift truck and a construction equipment vehicle being mounted simply by using a reduction gear on an axle input shaft, which is connected to a transmission, so as to enable easy parking braking with a small amount of force by means of a reduction ratio. In other words, the purpose of the present invention is to provide the device for the parking brake for the forklift truck and the construction equipment vehicle, which enables reducing the length of the axle input shaft having a more simple structure and easy parking braking with a small amount of force by means of the reduction ratio, by installing a reduction gear set for parking between a pair of thrust bearings that are mounted on the outer circumference of the axle input shaft for simultaneously operating as a spacer for each of the thrust bearings as well as a parking brake, and by connecting and mounting a hydraulic (automatic) or a mechanical (manual) brake control means to the reduction gear set for parking.
