    Abstract: Die Erfindung betrifft ein Zahnrad (10), insbesondere eines Schneckengetriebes. Mit Schmierfett geschmierte Zahnräder laufen nach einer längeren Betriebsperiode trocken, so dass es zum Verschleiß des Zahnrades, des Getriebes und durch Überhitzung auch zur Schädigung umliegender Bauteile kommt. Deshalb weist das erfindungsgemäße Zahnrad (10) ein Schmiermitteldepot auf.

    Abstract: Disclosed herein is a new improved large planetary gear system used on the input stage of wind turbine power generators. This improved planetary gear system reduces or eliminates lubricant debris traditionally generated from the gear teeth, thereby eliminating an initiating source for bearing failure. To achieve these results, some and preferably all of the gear teeth (4) within the planetary gear system (1, 2, 3) are superfinished using chemically accelerated vibratory finishing to a surface roughness of approximately 0.25 micron or less. Several objects and advantages of the invention are to provide a gearbox with reduced metal debris, improved bearing life, reduced wear, reduced vibro-frictional noise, improved contact fatigue, improved fretting resistance, improved lubrication, to simplify the run-in process, and to enhance the durability and efficiency of the gearbox.

    Abstract: A traction drive power transmission device, where a lubrication oil can be stably and continuously applied for a long period to portions at which rollers and a shaft are in contact with each other, shortage of the lubrication oil does not occur at the contact portions, the lubrication oil is not wasted, and which does not impair work environment by contaminating floor surface etc. A traction drive power transmission device has at least one drive roller (12a), a follower roller (12b), and a circular cylinder-like shaft (11). The shaft (11) is held between the drive roller (13a) and the follower roller (12b). When the drive roller (12a) is rotated, rotational force by the rotation is transmitted to the shaft (11) to drive it in its axial direction. The device has a lubrication oil-delivering portion (20) with application bodies (22-1, 22-2) for applying a lubrication oil only to portions where the shaft (11) is in contact with the drive roller (12a) and the follower roller (12b).

    Abstract: A large planetary gear system forming the input stage of a wind turbine power generator, has one or more of the planetary gears with gear teeth having contact surfaces from which the asperity peaks have been removed prior to run-in or installation. The resulting gear contact surfaces have an improved material ratio (Rmr) allowing for greater load bearing capacity and power density. Harmful metal debris caused by run-in is also prevented. The gear surfaces may be finished to a surface roughness Ra of less than 0.25 microns and may be specular in appearance.

    Abstract: A limited slip differential, comprising: a plurality of planetary gears; a planetary carrier for supporting the planetary gears in such a manner that the planetary gears can rotate on their axes and revolve while making contact with and sliding against a surface of teeth of the planetary gears; and a sun gear and a ring gear which are arranged coaxially with the planetary carrier and are allowed to differentially rotate by means of the planetary gears, wherein the limited slip differential limits differential motion generated between the sun gear and the ring gear, irregular unevenness is created on at least either of the surface of the teeth of the planetary gears, and the sliding surface of the planetary carrier which makes contact with and slides against the surface of the teeth, the limited slip differential being characterized in that:
    the surface where the irregular unevenness is created has such a surface roughness that the maximum value of the power of a pitch of 40 µm to 60 µm as found through Fourier analysis is 0.4 µm to 1.2 µm.
