本願考案はギヤボツクス等に組み込む歯車用の
シヤフトに関するものであり、尚詳しくは軸方向

車用のシヤフトである。[Detailed description of the invention] [Field of industrial application] The present invention relates to a shaft for a gear incorporated in a gearbox, etc., and more specifically, the invention is supported by three or more bearings in the axial direction, and has a shaft diameter that is proportional to the shaft diameter. This is a shaft for gears that can withstand large radial loads.

定長さの一体形シヤフトを用いる様にしていた。
Conventionally, shafts for gears, etc. transmit power through their rotation, so rigidity is required of the shaft. When joining multiple shafts to extend the length, welding or flange joints are used, but normally there is a risk of reducing the strength of the joint, so we do not form joints as much as possible for shafts for gears. In this way, an integrated shaft of a predetermined length was used.
上述の様に歯車用のシヤフトは一体形成され、
ラジアル荷重にも充分耐える様に剛性を与えられ

As mentioned above, the gear shaft is integrally formed,
It has a perfectly round and straight cylindrical shape that is rigid enough to withstand radial loads, and in order to support this shaft with three or more bearings, it is necessary to align the center lines of each bearing correctly. However, due to limitations in the machining accuracy of the machine case and bearings that support the shaft, it is difficult to install three or more bearings in the axial direction with their respective center axes completely aligned. It was hot. Therefore, the shaft for power transmission is usually supported in the axial direction by two bearings,
In addition, even though precision machines with relatively small loads may use three or more bearings in the axial direction, high precision is required for bearing positioning, etc., so manufacturing requires advanced technology and labor, resulting in lower manufacturing costs. The drawback was that it was expensive.
更に、シヤフトを２個の軸受等少数の軸受で支
持する場合、ラジアル荷重が増加するとシヤフト
直径を太くしなければならず、動力伝達用の歯車

の重量を増加させる欠点も有つた。 Furthermore, when supporting a shaft with a small number of bearings such as two bearings, the shaft diameter must be increased as the radial load increases, and shafts for power transmission gears require a large amount of material and have a large shape. Not only that, but it also had the disadvantage of increasing the weight of products such as gearboxes.

The present invention relates to a gear shaft to be incorporated into a gear box, etc., in which the shaft is composed of a plurality of shaft parts with the same outer diameter, so that the entire shaft is formed like a single shaft with a single diameter, and each shaft part is connected to each other. The joint part has a male part protruding from one shaft end and a female part recessed from the other shaft end, and the diameter l 2 of the male part is equal to the diameter l 1 of the shaft part. and slightly smaller than the diameter l3 of the female part, and the male part and the female part are brought together by grooves with concave and convex grooves such as splines, and each shaft part is connected at the joint part. Furthermore, the first shaft part is supported by two bearings, and the shaft parts after the second shaft part are each supported by one bearing, so that a single shaft is supported at three or more points in the axial direction.

This invention divides the shaft into multiple shaft parts,
A male part and a female part are formed at the joint part of each shaft part, and the diameter of the male part is made slightly smaller than the diameter of the female part, and the male part The extremely small gap between the shaft and the female part allows each shaft part to transmit rotation while allowing its axis to be slightly tilted. Furthermore, since each shaft portion is supported by a bearing, it is possible to withstand a large radial load even if the diameter of the shaft portion, that is, the diameter of the shaft is small.

The diameter l 2 of the shaft is smaller than the diameter l 1 of the shaft, and the diameter l 2 of the male part 16 is made slightly smaller than the female part 17 l 3 to eliminate play such as a spline, and the male part 16 and female part 17 are integrally formed.

Since the shaft part 11 and the second shaft part 12 are connected statically at the joint part 15, and the first shaft part and the second shaft part have the same diameters l 2 and l 4 , they appear as if they were one and the same. It is structured like the shaft of a book, making it easy to design the gear arrangement. Further, the first shaft part 11 and the second shaft part 12 are connected to the male part 16 and the female part 1.
7, the axis of the second shaft part 12 is aligned with the first shaft part 12 even in the statically coupled state.
Slight inclination with respect to the axis of the shaft portion 11 is allowed, and a slight misalignment of the axes of the bearings 21 and 22 can be absorbed, and the machining accuracy of the gearbox 25 and the bearings 21 and 22 can be relaxed, making manufacturing easier. This is particularly advantageous for gearboxes that transmit large amounts of power. . and,
Since it is possible to use a large number of bearings, gear 1
9 can be provided near the bearings 21 and 22, and even if the diameter of the shaft 10 is relatively small, it can withstand a large radial load and can transmit a large amount of power.
For example, the gear 29' can be replaced integrally with the two-shaft part 12 without removing the gear 29' fixed to the shaft part 12 and replacing it.
