Abstract

The utility model relates to a gearbox, wherein, each speed change stage is provided with a shaft; all shafts are arranged in parallel; the first shaft, a second shaft and a third shaft are supported by radial thrust bearings which are in X-shaped arrangement, and provided with tooth parts; the tooth parts are respectively meshed with gears which are connected with the second shaft, the third shaft and a fourth shaft in the shape locking manner; the first shaft and the second shaft are covered with a same bearing cover on the opposite sides; the second shaft and the fourth shaft are covered with respective bearing covers; the bearing covers are arranged in the detachable manner and in the manner that oil can not leak; the shape locking connection has very small gap, which is less than 10 minute of arc; the tooth profiles are designed into involute tooth profiles or modified involute tooth profiles; and the fourth shaft are designed into a hollow shaft so as to be in compact connected with a device to be driven.

Description

Gearbox

Technical field

The utility model relates to a kind of gearbox/retarder.

Background technique

Gear with involute profile is known.

The model utility content

The purpose of this utility model is, creates a kind of gearbox with high output torque.

According to the utility model, described purpose is achieved in having the gearbox of following characteristics:

For each speed change level of this gearbox is equipped with one, wherein all axles are provided with in parallel to each other,

Wherein first, second and the 3rd by means of the radial-thrust bearing of arranging with X-shaped to supporting and have tooth portion, described toothed portion not with second, the 3rd with the 4th with shape sealed/gear that the mode of form fit (formschl ü ssig) is connected is meshed

Wherein first hides by common bearing cap respectively on relative both sides with second, and the 3rd and the 4th hide by independent bearing cap respectively,

Wherein bearing cap is provided with oiltight and dismountable mode,

Wherein the sealed connection of shape is designed to have very little gap, especially less than 10 jiaos of branches,

Wherein flank profil is the involute profile of involute profile or correction of the flank shape,

Wherein the 4th is designed to hollow shaft, is used to realize that the compactness with device to be driven is connected.

At this advantageously, can produce above the high output torque of 100000Nm and described flank profil is only born very little load.If described tooth Profile Design becomes the helical teeth exterior feature, then gearbox long service life, running noises are very low.Gearbox can be very firmly and is made easily, that is need not to use high technology and be to use the standard machine tool manufacturing.

In an advantageous embodiments, can form a kind of gearbox designs series by described gearbox in simple mode, wherein by the replacing of replacement axle first and/or the 4th different modification that form this structural series to stretch out from the gearbox both sides,

Wherein will go out the replacement bearing lid that bearing cap on the side is replaced with relative set replacing shaft extension.

At this advantageously, can in described structural series, produce very big variation with a spot of parts.

Description of drawings

Now describe the utility model with reference to the accompanying drawings in detail:

Fig. 1 a illustrates the sectional elevation according to gearbox of the present utility model;

Fig. 1 b illustrates first and replaces axle;

Fig. 2 illustrates the plan view according to gearbox of the present utility model;

Fig. 3 illustrates corresponding side view.

Embodiment

Be bearing in for first 1 in the housing 15 of gearbox by a pair of radial-thrust bearing of arranging with X-shaped 2 and have tooth portion 3 with gear 4 engagements, this gear 4 is connected with second 10 by the key connection of the sealed formula of shape, this second has the tooth portion 5 of meshing with gear 6 again, and this gear 6 is connected with the 3rd 11 gaps tinily by the key connection of the sealed formula of shape.

Have the tooth portion 7 with gear 8 engagement for the 3rd 11, this gear 8 is connected with the 4th 9, the 4th side from gearbox stretch out and on opposite side by means of dismountable bearing cap 12 coverings.The 4th 9 by means of bearing 21 supporting and be designed to hollow shaft, so that can realize installing very compactly other device.

Hide by bearing cap 14 and on a relative side, hide for second 10 by another bearing cap 20.

On both sides, hide for the 3rd 11 by bearing cap 13.

Housing has transportation with suspension ring 16, can be easy with suspension ring and easily transport housing by these transportations.

All axles are all directed in parallel with each other.The weight of gearbox is located between the double centner to 10 ton according to the difference of size.

Fig. 1 b shows 100, the first 1 on the first replacement axle and can be substituted by this first replacement axle, thus another modification of formation gearbox.First replaces axle 100 stretches out from the both sides of gearbox.

In a word, can produce a kind of different modification of structural series for different applicable cases, and only need use and lay in few parts.

First, second and the 3rd is designed to solid shaft respectively.
