Embodiment Construction

[0020] refer to figure 1 , figure 2 , the present invention is mainly made up of four components, namely the planetary inner frame (5) with connecting plate is socketed with the planetary outer frame (3) with orifice plate, the connecting plate on the planetary inner frame (5) [(5) The middle position of -①] is to install a connecting piece (7) that transmits torque [such as a cylindrical pin or a connecting piece of other shape], and has an annular joint surface with the smallest axial dimension that can closely match the size of the connecting piece (7) [3-②], the inner and outer planetary frames (5, 3) are connected with connectors (7) and fixed with fasteners (6) [such as fastening bolts or other fasteners], the planetary outer frame after assembly (3) contact with the planetary inner frame (5) only at the ring joint surface [3-②], and other positions are suspended in the air. The orifice plate [3-①] of the outer planetary frame (3) is provided with a hole for fixing th...

Abstract

The invention discloses a combined planetary carrier for wind power generation, jacketing an inner planetary carrier having connection plates with an outer planetary carrier having orifice plates, where each connection plate can be provided with torque transmission connection piece only in the middle and has annular bonding surface able to tightly cooperate with the connection piece , the inner and outer planetary carriers are interconnected through connection pieces, and fastened through fastening pieces, and after assembled, the inner and outer planetary carriers contact only on the annular bonding surface and the other parts are suspended in the air. Because the torque acts on the middles of the connection plates, the axes of planetary and central gears are always parallel mutually, and it largely prolongs the service life of planetary bearing and assuring the reliability of planetary gearing. The invention is especially applied to the occasion of variable torque input.

Description

technical field [0001] The invention relates to the innovation of a planetary gear box planet carrier for power generation speed-up, in particular to a combined planet carrier, which is especially suitable for planetary gear speed-up between blades of a wind power generator and a generator. Background technique [0002] In a general planetary gearbox, the deviation angle between the axis line of the planetary gear and the axis line of the center wheel is proportional to the transmission power or torque of the gearbox. The load and the partial load of the two planetary bearings seriously affect the reliability of the calculated bearing life. In particular, the megawatt-class wind power planetary gearbox is a typical low-speed heavy-duty variable torque power transmission. In engineering applications, gear modification is generally used to solve such problems. However, since the gear modification is designed according to a certain constant torque (working point) Yes, in diffe...
