Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0019] figure 1 It is a schematic diagram of a wind power generator to which a grease supply system according to an embodiment of the present invention can be applied.

[0020] The wind power generator 10 includes blades 11 , struts 12 , and a spinner 13 . The blade 11 is composed of a plurality of blades provided at the front end of the main shaft 14, and the main shaft 14 is rotated by wind. The spinner 13 includes a main shaft 14 , a support mechanism 15 , a speed increaser 16 , a generator 17 , a casing 18 and the like. The support mechanism 15 supports the main shaft 14 . The speed increaser 16 speeds up the rotation of the main shaft 14 . The above-mentioned generator 17 generates electricity by the rotational power accelerated by the speed increasing gear 16 . The housing 18 accommodates the above components. The strut 12 supports the cowl 13 so a...

Abstract

The invention provides a grease supply system for rolling bearing. A grease supply system includes a discharge portion that forcibly discharges a grease from a rolling bearing, a discharge amount measuring portion that measures a discharge amount of grease, a replenishing amount setting portion that sets a replenishing amount of grease on the basis of the discharge amount of grease measured by the discharge amount measuring portion, and a supply portion that automatically replenishes the rolling bearing with the set amount of grease.

Description

technical field [0001] The present invention relates to a grease supply system for supplying grease to rolling bearings that support a main shaft of a wind power generator, etc. Background technique [0002] Wind power generation is attracting attention again as a power generation method that does not emit carbon dioxide and has a small impact on the environment, and is rapidly spreading around the world. In addition, in recent years, wind power generators have been installed not only on land but also on seas where layouts less affected by topography can be secured and noise problems can be alleviated. On the other hand, since it is more difficult to perform maintenance on wind power plants, it is desirable to reduce the frequency of maintenance. [0003] Japanese Patent Application Laid-Open No. 2010-159710 discloses a technology capable of reducing the frequency of maintenance by estimating when maintenance is required by grasping the operating conditions of a wind power ...
