The invention relates to a method for assembling (S) a planet carrier (16), comprising the following steps: separately producing (S1) the cage (20) and the cage carrier (30), providing a machining allowance at one element from among the through-holes (23, 25) in at least one upright (21) of the cage (20) or the through-hole (32) in a finger bar (31) of the cage carrier (30), and/or at one element from among a bearing seat (26) or a rolling bearing seat (41, 42); assembling (S2) the cage (20) and the cage carrier (30) and securing (S3) same to produce a one-piece assembly; determining (S4) the position of a reference axis (Y1, Y2) linked to the cage (20), to the cage carrier (30) and/or to the shaft (40); and, taking account of the position of the reference axis (Y1, Y2), machining (S5) all or part of the machining allowances.

A jig includes: a first gear part that can be meshed with an input gear disposed in a casing by being inserted into the casing from the outside of the casing; a torque application part that is fixed to the first gear part, is disposed outside the casing in a state in which the first gear part is meshed with the input gear, and is capable of applying a torque about a first axis, which corresponds to an axis of the first gear part, to the first gear part; and a phase indicator provided on the torque application part to indicate the phase of the first gear part about the first axis.

A modular gearbox assembly for a wind turbine having improved up-tower serviceability includes a low-speed gear stage module, a separate, intermediate-speed gear stage module adjacent to the low-speed gear stage module, and a separate high-speed gear stage module adjacent to the intermediate-speed gear stage module. The gearbox assembly also includes a first flange removably connecting the intermediate and high-speed gear stage modules and a second flange removably connecting the intermediate and low-speed gear stage modules. Thus, the low-speed gear stage module converts a low-speed, high torque input from a rotor shaft of the wind turbine to a high-speed, low torque output for a generator of the wind turbine via the intermediate and high-speed gear stage modules. In addition, the first and second flanges allow for easy disassembly of the gear stage modules such that the various stages can be easily repaired, replaced, and/or inspected.

The invention relates to equipment (40) for disassembling a planet carrier (14), said planet carrier (14) comprising: a cage (20) comprising an inner bridge (24) and an outer bridge (26); a cage carrier (30) comprising at least one finger bar (31) to be inserted between the inner bridge (24) and the outer bridge (26); and a connection shaft (14) housed in through-holes (25, 27, 33) formed in the bridges (24, 26) and in the finger bar (31), such as to retain the cage (20) on the cage carrier (30). The equipment comprises: a jack (41) including a body and a piston (42), said piston (42) being designed to apply a force to the connection shaft (14); and a support (43) designed to bear on the finger bar (31) when the piston (42) applies a force to the connection shaft (14).

A tool system for installing a parking pawl includes a tool that includes a base, a plate, and an actuator. The base includes a base surface configured to support a parking pawl in a predetermined position. The plate includes a protrusion that extends upward from a front portion of the plate. A rear portion of the plate is coupled to a front portion of the base. The plate is movable relative to the base between a retention position in which the protrusion is positioned to retain a pawl spring loaded on the parking pawl in a pretensioned state, and a release position in which the protrusion is configured to release the pawl spring. The actuator is operably coupled to the plate such that activation of the actuator moves the plate between the retention position and the release position.

Disclosed is a transmission remover and installer, for removing and installing transmissions, which comprises a plate defined by a top surface and bottom surface; a connecting means at a first end of the plate traversing through a hole in the plate, installed using a first securing means on the top surface and a second securing means on the bottom surface of the plate; a mounting means securing the top of the connecting means using a first protrusion located at the bottom of the mounting means; and a jack adapter coupled at the bottom surface at a second end of the plate. The mounting means has a first hole and a second hole configured to couple with a transmission after identifying a balance point of the transmission and the jack adapter has a coupling means enabling the jack adapter to be coupled with a jack after identifying a balance point.

A removal tooling for a clutch of a gearbox includes an upper bracket, a lower bracket, a main screw and a pulling claw. The upper bracket has a middle portion vertically provided with threaded holes, and a bottom surface fixedly connected with connecting posts distributed at equal angular distances around an axis of the threaded hole. The lower bracket has a main body fixedly connected to a lower end of the connecting post, and a circumference of the main body has cantilevers distributed at equal angular distances around the axis of the threaded hole. The main screw penetrates through the threaded hole from top to bottom. There are a plurality of pulling claws which are fixed on a bottom surface of the cantilever in one-to-one correspondence, and a lower end of the pulling claw forms a claw portion which is buckled inward.

A planetary gear mechanism includes a plurality of planetary gears, an outer gear, a sun gear, a carrier, and a stick mount. The outer gear meshes with the plurality of planetary gears. The sun gear is coaxially disposed on the same axis as the outer gear and transmits force to the planetary gears. The carrier rotatably supports the plurality of planetary gears and is rotatably and floatingly supported. The carrier includes a hole through which a stick member penetrates in a direction of axis of rotation of the carrier. The stick member penetrates through the hole and is mounted on the stick mount. The stick mount is disposed opposite the carrier. The outer gear and the sun gear are held such that one of the outer gear and the sun gear does not rotate.

A strain wave gearing has three components and a temporary-fixing jig, three components being an internally toothed gear, a cup-shaped externally toothed gear, and a wave generator. The temporary-fixing jig is securely fastened to an output shaft fixed to the externally toothed gear by a temporary-fixing bolt and is securely fastened to an input shaft fixed to a cam plate of the wave generator by a temporary-fixing bolt. The temporary-fixing jig engages with the output shaft and the input shaft and maintains the three components in an assembled state. There is no need for an operation for adjusting the positions of the three components in an operation for attaching the strain wave gearing to a motor. After the strain wave gearing has been attached to the motor, the temporary-fixing jig is removed from the strain wave gearing, wherefore less space is required for installation.

A gear device includes a gear attached to a shaft to rotate integrally with the shaft, a pair of bearings located across the gear in a direction in which the shaft extends and supporting the shaft in a rotatable manner, and a plurality of removable members attached to the gear. The plurality of removable members are attached to two surfaces of the gear intersecting with the shaft. Each removable member of the plurality of removable members faces a bearing of the pair of bearings located across the gear.
