Abstract

The utility model relates to a bevel gear gearbox, wherein, each speed change stage is provided with a shaft; all shafts, except for a first shaft, are arranged in parallel; each shaft is supported by at least a couple of radial thrust bearings which are in X-shaped arrangement; the first shaft is provided with a first meshing component or connected with the first meshing component; the first meshing component is meshed with another meshing component which is in key connection with a second shaft in the shape locking manner; the second shaft and a third shaft are respectively provided with teeth parts which are meshed with gears which are in key connection with the third shaft and a fourth shaft in the shape locking manner; the third shaft and the second shaft are covered with a same bearing cover on the opposite sides; the fourth shaft is covered with an independent bearing cover; 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; the teeth parts of the second shaft and the third shaft are designed into involute tooth profiles or modified involute tooth profiles; the first meshing component and another meshing component are designed into bevel gears or form helical plane speed change stage, hypoid gear speed change stage or crown shape gear speed change stage.

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 bevel gear gearbox (Winkelgetriebe) of feature as described below:

For each speed change level is equipped with one, wherein the axle of all except that first is provided with in parallel to each other,

Wherein each supports by means of at least one pair of radial-thrust bearing of arranging with X-shaped,

Wherein first reel structure has first engaging member or is connected with first engaging member, this first engaging member with second with shape sealed/mode of form fit (formschl ü ssig) is connected another engaging member engagement that is connected by key,

Wherein second and the 3rd has tooth portion respectively, described toothed portion not be meshed with the 4th gear that is connected in the sealed mode of shape with the 3rd,

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

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 second and the 3rd tooth portion is designed to the involute profile of involute profile or correction of the flank shape,

Wherein first engaging member and another engaging member are designed to the bevel gear or first engaging member and another engaging member and form helical planes speed change level (Spiroplangetriebestufe), hypoid gear speed change level or crown gear speed change level.

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 changing the 4th different modification that form this structural series with the replacement axle that stretches 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.

In another advantageous embodiments, the axis coplane of four axles.

In another advantageous embodiments, second, third and the 4th axis coplane, and the axis existence of first axis and its an excess-three axle is offset.

At this advantageously, can in described structural series, produce 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 c illustrates the 4th 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 the housing 15 of gearbox by two pairs of radial-thrust bearings of arranging with X-shaped 2 for first 1.On first 1, be connected with bevel gear 300 in the sealed mode of shape by means of the key connection, this bevel gear and gear 4 engagements that are designed to bevel gear, this gear 4 is connected with second 10 by the key connection of the sealed formula of shape, this second 10 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.

Hide by bearing cap 14 jointly with the 3rd 11 and on a relative side, hide for second 10 by another bearing cap 20.

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

Except first, 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 c shows 900, the four 9 on the 4th replacement axle and can be substituted by the 4th replacement axle, thus another modification of formation gearbox.The 4th replaces axle 900 also 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.

All axles are solid shaft.

In other modification, first be not with other axle coaxially (koaxial) arrange that as shown in Figure 1a, that is to say, axle 1 and other mathematics axis are non-intersect, but have journal offset.In this case, the difference according to velocity ratio is provided with hypoid gear, helical planes tooth or crown tooth rather than awl tooth.
