Description

The invention relates to a transmission with a housing which supports at least one bearing by means of at least one bearing, wherein the housing has a bearing bell, in which the example. Formed as a rolling or sliding bearings bearing / inserted, is pressed about, and wherein in the Bearing bell is formed at least one formed as a recess or recess lubricating fluid collecting and -Leittasche.

The invention relates generally to gearboxes in which gears, such as spur gears are mounted on shafts. In particular, such transmissions are used in Richterregern for vibrating machines. Such vibrating machines are designed as vibratory conveyors or vibrating screens. The invention therefore also relates to Richter exciter for such vibrating machines, namely vibrating conveyor and / or vibrating screens and such a vibrating machine.

Compared to the use of unbalance motors, the exciters have the advantage of defined power flows and defined mechanical loads in a vibrating machine. The vibration data are independent of loads due to the bulk material.

Rolling and gears are in a cast housing and are usually oil lubricated, lubricated about Öltauch. The maintenance is usually limited to an occasional oil level check or an oil change at prescribed time intervals. At standstill, the imbalance masses / imbalance weights can be changed by installing and removing additional masses. In this case, imbalances of steel or lead can be compensated. The Richterreger is usually driven via a propeller shaft by a standard electric motor from the outside. Suitable maintenance-free drive shafts are available for judge exciters. If required, braking devices can be used for the reduction of outflow vibrations and frequency converters for the stepless variation of the centrifugal forces, and thus the delivery rate.

Judges generate a force F with a sinusoidal course, which acts along a line. A Richterregger has two waves aligned with imbalance masses. These imbalance masses are synchronized by the built-in gear transmission to gegensinnigem circulation with the same speed.

Such judges are economical and provide a powerful drive, even with high required services. They have a long excitement life and a high running smoothness. Only a small amount of maintenance is caused by them. The noise level caused by them is very low. It is advantageous that such devices have a 98% availability that predestines them for use in continuous operation.

It is the object of the invention to provide an improvement here. The disadvantages of the prior art should be remedied, or at least mitigated. In particular, it is the object to effect a forced guidance of oil, which is often used as a lubricating fluid, which leads to a long-lasting Richterregerausgestaltung. Gear per se should be more durable, but still be inexpensive to produce.

This object is achieved in a generic device according to the invention in that the lubricating fluid collecting and -Leittasche and a lubricating fluid distributor ring / lubricating fluid distribution ring are in operative relationship with each other, that a targeted lubricating fluid guide is forced to the camp.

Usually, two bearings per shaft in use, which are usually similar, so both are designed as rolling or sliding bearings. Of course, a combination of a rolling bearing with a plain bearing is conceivable.

On the waves are, especially in Richterregern, gears, such as spur gears, mounted about straight or helical gears. Usually, such gears are inserted between the two bearings. In Richterregern it is common to use two shafts, which are mounted on two identical bearings, wherein between each of these bearings on each shaft a spur gear is mounted, which meshes with the attached to the other shaft spur gear.

By the use of the lubricating fluid distributor ring at a suitable location dripping lubricating fluid is spent targeted to non-lubricating parts of the bearing over in a region of the bearing to be lubricated. Even over a long period of use, a fail-safe operation of the transmission or the Richterregers is possible.

Advantageous embodiments are claimed in the subclaims and are explained in more detail below.

Thus, it is advantageous if the distributor ring is designed on the outer diameter with one or more recesses which form an opening between the outer ring of the bearing and a retaining ring in the lubricating fluid collecting and guide pockets and thus ensure a lubricating fluid supply of the bearing and / / or a plurality of lubricating fluid collecting and -Leittaschen are distributed over the circumference of the bearing bell. Dripping lubricating fluid can then be used efficiently Bearings are spent. In order to be able to resort to proven lubricants, it is advantageous if oil is used as a lubricating fluid, such as mineral oil.

It is advantageous if the lubricating fluid distributor ring is formed as a bearing and the bearing bell as a separate component. The assembly is facilitated.

Lubrication and positive conduction are enhanced when the lubricating fluid distribution ring is disposed within, or adjacent to, the lubricating fluid collection and supply pocket. In this case, the lubricating fluid distribution ring is more than twice, preferably three times its thickness away from an axially spaced from the bearing edge of the lubricating fluid collecting and -Leittasche. A targeted oil routing is then simplified.

In order to secure the bearing efficiently and at the same time to make the lubricating fluid guide efficient, it is advantageous if the lubricating fluid distributor ring between an outer ring of the bearing, such as a bearing outer shell / a bearing outer ring and a retaining ring / snap ring is arranged.

Again, it has been found to be advantageous if the retaining ring is arranged in or on the lubricating fluid collecting and -Leittasche, for example adjacent thereto. An advantageous embodiment is also characterized in that the lubricating fluid distributor ring has on its side facing away from the bearing an inclined to the longitudinal axis of the bearing lubricating fluid guide surface. A one-sided or two-sided wedge surface is advantageous. Also, a spherical, curved, convex or concave configuration of the lubricating fluid guide surface may be useful.

To ensure that the lubricating fluid dissolves well from the also as a guide plate lubricating fluid distributor ring, it is advantageous if a drip edge for lubricating fluid is formed on the lubricating fluid distributor ring.

Although the lubricating fluid distributor ring may then end up forming a drip edge, it is particularly advantageous if the drip edge is formed by the radially inner edge of the distributor ring. A manufacture of the ring can then be easily made, especially if it is made of metal, such as a steel alloy.

If the drip edge is arranged at the radial height of rolling elements or a bearing gap, d. H. preferably axially adjacent to the rolling elements or the bearing gap, due to two sliding partners, is arranged, the lubricating fluid can be supplied to the partners to be lubricated as quickly as possible, so that damage to the partners is avoided. The drip edge then ends next to the rolling elements or the bearing gap.

In particular, the invention relates to a judge exciter for a vibrating machine, such as a vibrating conveyor and / or a vibrating screen, with a transmission according to the invention.

The invention also relates to such a vibrating machine with such a Richterreger.

The special feature of the invention is that an angle-independent solution is provided, so anywhere in the housing of the rotationally symmetrical lubricating fluid distributor ring can be arranged so that regardless of the installation situation always a good lubricating effect is achieved. While otherwise was set to holes, but serve with appropriate rotation, rather than drain as an inlet, now an always uniform, good and efficient lubricating fluid supply is guaranteed.

Judge exciters can be placed in any position on a vibrating machine, preferably at an angle of about 45 ° to the horizontal, but also vertical and overhead positions are common. As a result, bearings known from the prior art which are to be supplied with lubricating fluid can not be used. This is evident, for example, in rolling element bearings. ensure the lubrication fluid supply via a groove in the outer ring and arranged therein radial holes. These measures are in fact used to ensure a lubricating fluid supply. The arbitrary arrangement of the Richterreger the lubricating fluid would drain into the holes below, but this is undesirable. Conventional constructive solutions - which then close these holes according to the arrangement position of the exciter - are very expensive. However, the invention makes it possible to dispense with otherwise expensive solutions, such as the use of pumps and nozzles.

The invention will be explained in more detail with the aid of a drawing, in which a first embodiment is shown in more detail. Show it:

10 a longitudinal sectional view in the region of a rolling bearing, which is seen between a bearing bell and a shaft seen in the radial direction and axially disposed between a side cover and a gear, with bearing mounted lubricating fluid distributor ring.

The figures are merely schematic in nature and are only for the understanding of the invention. The same elements are provided with the same reference numerals.

In 1 is a vibrating machine 1 presented on which a judge 2 that is a case 3 has, is attached. The judge 2 causes an excitement in the direction of an arrow 4 is caused. In 2 is the judge 2 with his case 3 reproduced in an enlarged view. It can be seen that two waves 5 are used, on which imbalance weights / imbalance masses 6 , which can also be referred to as vibrating segments attached.

The overall structure of the judge in perspective perspective, goes out 3 which visualizes that on every wave 5 four imbalance weights 6 are present, with two each on one side of the housing 3 available. The housing 3 is with a lid 7 closed, so that every wave 5 associated gear 8th the view is withdrawn.

Regarding the gear 8th will be on the 5 directed. A look inside, however, is already in the 4 allows. That's the case 3 split in two, so that every part of the case 3 two camp bells 9 , which could also be referred to as bearing flanges has. In the camp bells 9 are lubricating fluid collecting and guiding bags 10 educated. To the lubrication fluid collection and supply pockets 10 can through the case 3 formed footbridges 11 limits.

There are lubrication fluid collection and vent pocket free areas on the bearing bell 9 , So those areas in which with a uniform distribution of the lubricating fluid collecting and -Leittaschen 10 some of the lubricating fluid collection and supply pockets 10 absence. The lubricating fluid collecting and feeding pockets 10 are channel-like and thus form in the radial direction aligned and open in the axial direction grooves. They are through the casting material of the housing 3 formed. They are urgeformt, but can also be introduced milling.

The waves 5 be over camp 12 as well as in 5 are indicated, stored. Here is the respective camp 12 designed as a rolling bearing, in particular (pendulum) roller, barrel or ball bearings. The rolling elements are denoted by the reference numeral 13 characterized.

In 6 are the camp bells 9 , for picking up the bearings 12 clearly visible. Also, they are axially projecting lubricating fluid guide channels 14 , which are formed as through holes, in particular on the type of holes to recognize. They control a lubricating fluid balance. There is so much lubricating fluid in the housing 3 contain, namely (mineral) oil, that is a lubricating fluid sump 15 forms.

The two gears 8th are in intermeshing relationship with each other. The gears 8th have on their outside a toothing 16 on, namely a straight or helical external teeth. By the rotation of the waves 5 and the gears 8th becomes lubricating fluid in the interior of the housing 3 distributed.

The lubricating fluid can then, for example, passed through the webs 11 or due to gravity or Zentripedalkraftbedingt, by the lubricating fluid collecting and -Leittaschen 10 how they are good in 8th can be seen in the interior of the bearing bell 9 reach. At the same time, the lubricating fluid collecting and guiding pockets open 10 on peripheral surfaces 17 and 18 a lubricating fluid distributor ring 19 or a circlip 20 , It is beneficial if a jetty 11 centrally in a lubricating fluid collecting and carrying bag 10 opens, that is arranged centrally in her, that defines an axially oriented projection in the interior of the channel. It can then lubricate fluid from both sides into the lubricating fluid collection and supply bag 10 reach.

The lubricating fluid distributor ring 19 points as in 9 is easy to see, as well as in 10 , a radially inner edge 21 on, as a drip edge 22 acts.

A radially outer peripheral surface of the lubricating fluid distributor ring 19 is arranged radially further inside, as a peripheral surface of the retaining ring 20 , Between a bearing outer ring 23 and a bearing inner ring 24 of the camp 12 are the role or barrel-shaped rolling elements 13 arranged. On an outside of the case 3 , a side cover works 25 along with a seal 26 such as a labyrinth seal and a felt ring 27 sealing, with axially further bearing side a spray disk 28 is available. Also is on the side facing away from the disk of the bearing 12 , between the gear 8th and the bearing inner ring 24 radially inside the lubricating fluid distributor ring 19 and the circlip 20 a spacer sleeve 29 arranged. The radially inner edge 21 the lubricating fluid distribution ring 19 is radially further inside than a radially inner edge 21 of the circlip 20 arranged.

Lubricating fluid thus runs the lubricating fluid collecting and Leittasche 10 along, penetrates between the circlip 20 and the bearing outer ring 23 through on the gear-side surface of the wedge-shaped lubricating fluid distributor ring 19 along, and drips in the area of the drip edge 22 down to the rolling elements 13 to supply.
