摘要:
A method for changing the pre-stretch level of a stretch-film wrapping machine, in which method the pre-stretch level is changed by changing the transmission ratio of a power transmission gears (3, 4; 13, 14) coupling a first pre-stretching roller and a second pre-stretching roller of a pre-stretching device, wherein the pre-stretch level in changed by replacing the power transmission gears (3, 4; 13, 14) coupling the first and second pre-stretch roller located on a surface of the pre-stretching device. The invention relates also to a pre-stretching device, a stretch-film wrapping apparatus and a detachable gearbox (12).

The aim of the invention is to provide an especially light-weight main shaft or countershaft for a transmission. The transmission of high torques, such as is the case for the main shaft or countershaft of a transmission, is problematic when the base of the shaft consists of a fiber composite material. A metal element (20, 22) is laminated into the base, a gear (28, 30) being force-lockable with the metal element (20, 22) in such a manner that high torques can be transmitted.

A drive train (22) for a rescue hoist includes a first stage (60), a second stage (62), and a third stage (64). The first stage receives an input from a motor and the third stage provides rotational power to a cable drum. The first stage, second stage, and third stage are disposed coaxially within a common housing. The first stage provides a first speed reduction, the second stage provides a second speed reduction, and the third stage provides a third speed reduction between the motor and the cable drum. The common housing includes a mounting flange for mounting the drive train to the rescue hoist.

A mounting system for a planetary gear train (30) in a gas turbine engine (10) comprises a support strut (56), a deflection flange (74) and a deflection limiter (52). The support strut extends between a stationary engine case (42) and a rotating engine shaft (22) that provides input to the planetary gear train in the gas turbine engine. The deflection flange extends from a rotating output component (68) of the planetary gear train. The deflection limiter is connected to the support strut and engages the deflection flange when the gear train becomes radially displaced.

A power take off unit includes an output gear having a hydraulic circuit. The hydraulic circuit is an internal hydraulic circuit that is in fluid communication with an internal clutch assembly. The hydraulic circuit includes a flow-restrictive passage that modulates the flow of hydraulic fluid in order to provide a soft start clutch engagement that reduces shock loads associated with loads produced when starting torque is applied to the attached equipment.

A lubricating device for transmission includes a rotational shaft (112) provided in a transmission housing (101), bearings (121,122) attached to the transmission housing (101) for supporting the rotational shaft (112), a cylindrical rotational member (11) fixed to the rotational shaft (112) between the bearings (121,122) at an outer peripheral of said rotational shaft (112), at least one oil delivery groove (11b.11c) which is spirally formed on an outer peripheral surface of the cylindrical rotational member (11), the outer peripheral surface of the cylindrical rotational member (11) being covered by a rotational member housing portion (101a) of the transmission housing (101).
摘要:
A gear shaft (305) allows a ceramic bearing to be used in environments where gear steel is desirable for driving a gear (337). The gear shaft (305) includes a gear region and a bearing region. A bearing can be disposed about the bearing region of the gear shaft (305). A gear (337) can be disposed about the gear region of the gear shaft (305). The bearing includes a ceramic material. The gear region of the gear shaft (305) includes gear steel, whereas the bearing region of the gear shaft (305) includes a bearing-region material that has a coefficient of thermal expansion (CTE) that is close to the CTE of the ceramic material.
