DE102007058904A1 - Gearbox, has two engaging components designed into bevel gears, and housing composed of upper housing component and lower housing component, where contact plane of housing passes through axial lines of shafts - Google Patents

Abstract

The gearbox has two shafts separately covered with bearing caps at two opposite sides, where the bearing caps are detachably configured in an oil tight mode. Toothed parts are designed with involute and modified toothed outlines. Two engaging components are designed into bevel gears and formed into spiral plane transmission stages, hypoid gear transmission stages or crown gear transmission stages. A housing is composed of an upper housing component and a lower housing component, where the contact plane of the housing passes through axial lines of the shafts.

Description

The The invention relates to a transmission.

Gears with Involute gears are known.

Of the Invention is based on the object, a transmission with high output torque to create.

According to the invention Task in the transmission according to the features specified in claim 1 solved.

Essential features of the invention in the angular gear are that each gear stage is associated with a shaft, with all but the first shaft all waves are arranged parallel to each other,
wherein each shaft is supported by means of at least one pair of angular bearings in X-arrangement,
wherein the first shaft is designed or connected to a first toothed part which engages with a further toothed part, which is connected to the second shaft in a form-fitting manner by keyed connection,
the second having a gearing portion engaged with a gear that is positively connected to the third shaft,
wherein the third and second shafts are each covered by a separate bearing cap on both opposite sides,
wherein the bearing caps are provided oil-tight and detachable,
wherein the positive connection is carried out with little play, in particular with less than 10 angular minutes,
wherein the toothing region of the second shaft is designed as involute gears or modified involute gears,
wherein the first and further gear part is designed as a bevel gear or the first and further gear part form a Spiroplangetriebestufe, a hypoid gear stage or a Kronenradgetriebestufe,
wherein the housing is composed of an upper housing part and a lower housing part, the contact plane passes through the axes of the waves, that contains them.

From The advantage here is that high output torques over 100 000 Nm are generated and the gears only slightly loaded become. The gearboxes have a long service life and run very quietly, if the gears are helical gears accomplished become. The gears are very sturdy and easy to manufacture, so not with high technology but with standard machine tools.

In an advantageous embodiment, a series of transmissions can be formed from the transmission in a simple manner, with different variants of the series being produced by exchanging the fourth shaft for an exchange shaft which protrudes from the transmission on both sides,
wherein the bearing cap on the side from which protrudes the exchange shaft is exchanged for a correspondingly provided replacement bearing cap.

From The advantage here is that with few components a high variance can be produced in the series.

The invention will now be explained in more detail with reference to figures:
In the 1a is shown a cross section through the transmission according to the invention. In 2 is a plan view and in 3 an associated side view.

A first wave 1 is over two X-array pairs of skew bearings 2 stored in the housing 15 of the transmission. On the wave 1 is a bevel gear 300 positively connected by means of a feather key, which with a gear designed as a bevel gear 4 is engaged, via a positive key connection with the second shaft 11 which in turn is a gearing area 7 which has a gear 8th is engaged, via a positive key connection with the third shaft 9 is connected with little play.

The third wave 11 protrudes from one side of the gearbox and is on the other side by means of a detachable bearing cap 12 covered.

The second wave 11 is through a bearing cap 14 covered and on the opposite side by another bearing cap 14 ,

The housing has eyebolts 16 on which it is easy and easy to transport.

The housing is made of an upper housing part 151 and a housing lower part 152 manufactured, which are tightly interconnected, being at the joints 1000 Screw connections are executable. In this way, the production is very simple, since the bearings and shaft are lowered from above into the lower part and then the upper part is fastened on it.

With the exception of the first wave, all waves are aligned parallel to each other. The weight of the gearbox is depending on the size between 100 kg and 10 tons.

In 1b is a fourth wave of exchange 900 shown by the third wave 9 is replaceable, whereby a further variant of the transmission is formed. The fourth exchange wave 900 in turn protrudes from both sides of the gearbox.

All in all are thus for different use cases various variants of a series produced, with only a few Components must be used and stockpiled.

All Waves are full waves.

In other variants, the first wave is not coaxial with the other waves as in 1a arranged, so intersect the mathematical axes of the wave 1 and the other waves not, but there is a misalignment. In this case, depending on the translation no bevel gear but hypoid, Spiroplanverzahnung or crown gear teeth provided.
