¹¹ device for compacting soil masses or the like. "

The innovation relates to a device such as alze or the like. For compacting soil or the like., In particular for road construction with one and / or more, in Seitenbleohen rotatably mounted Unwuehtwellen and two and / or more roller bodies or the like., whose axes in roller bearings or the like. in the Side plates are provided rotatably, with a drive

device with "transmission gears the unbalanced shafts in vibratory oscillations and the roller body synchronously with it offset a forward movement.

In the "previously" known devices of this type (rollers) sum compaction of soil masses or the like. are the roller bodies rotatably mounted with their axes in roller bearings or the like. These roller bearings form the axle bearings of the side plates and are at the way the roller body works, the unbalanced masses of a exposed to permanent vibratory oscillation, which has the effect of shock-like pressure load. The rolling bearings show less disadvantage A hard (rigid) mounting and the permanent pressure loads lead to damage or destruction of rolling bearings · These rolling bearings have to be more elaborate

They are exchanged at certain intervals j your barrel time is due to the unfavorable storage / disadvantageous way

relatively low

The task of the inflation rate is to provide a device such as a roller or the like. for compacting soil or the like. to create at the

the? Jälzlager in favorably show a soft (elastic) mounting, whereby with favorable transmission of the vibration oscillations the unbalanced masses on the roller body the roller bearings absorb the resulting pressure loads attenuated} and with safer Effectiveness and long service life avoid the previous disadvantages.

According to the innovation, a device such as a roller or the like is. to the Compaction of soil etc. * especially for road construction > with one and / or more rotatably mounted in side plates Unbalanced masses, such as TJnwuchtwellen or the like. and two / or several roller bodies or the like., whose axes in roller bearings or the like. are provided rotatably in the side plates, wherein a drive device with transmission gear in the unbalance shafts Vibration oscillations and the roller body synchronously set in a forward movement, characterized in that the Axes of the roller body or the like. rotatably receiving roller bearings are encased by a damping layer.

In a preferred embodiment, the damping layer can be made of an elastic material, preferably rubber or the like. to be made

The damping view can preferably be around the rolling bearings Arrange in a ring and at least the width of the bearing width train accordingly * The damping rail can

When the roll or the like according to the innovation. are in more advantageous Way the roller bearings receiving the roller body axes or the like. of a damping layer made of an elastic material surrounded, whereby the jerky pressure loads of the unbalanced masses are intercepted in a favorable manner, and without any pressure reduction be passed on to the roller body. The elastic mounting of the roller bearings will cause damage Tdzvi ·. Destruction of the same avoided in a simple manner and the rolling bearings show a long service life with consistently good running properties despite permanent pressure loads

A device such as a roller or the like. for compaction, τοη soil masses Or the like., In particular for road construction, is for example ntt two roller bodies or the like. lo, ll fitted that each arranged in parallel by means of an axis 12, 13. Side plates 14 rest rotatably in axle bearings 15 (cf. 3? Ig.l)

The axle bearings 15 xireisen each one around the front ends of the axes 12, 13 arranged roller bearing 16, such as ball bearings, roller bearings or the like, the τοη a ring-like, for example Damping layer 17 are coated. This cushioning layer

"is preferably made of an elastic material, such as Rubber or the like. and extends to the entire width of the Rolling bearings 16 j the damping layer 17 wix-d each from one bearing ring 18 held stationary in aen side plates 14 and includes »so that the damping layers 17 with the roller bearings 16 by means of the bearing rings 18 in the side plates 14 are stationary form storage location. The axle bearings 15 can be of a cap, not shown, or the like. cover.·

The side plates 14 are in the region of their upper corners _;

Unbalanced masses "as unbalanced shafts 21» 22, which preferably \ are arranged outside of the vertical through the axes 12, 13 planes extending outwards. \

The uncomfortable masses are preferably around half a ι

These unbalanced shafts 21, 22 are driven by one Motor 23 via an over and / or reduction gear 24 by means of belts or chains, with a chain or the like. can drive the unbalance shafts 21, 22 together (not shown). The center of gravity of the motor 23 is exactly in the middle between the roller bodies lo, 11; the motor 23 and the transmission 24 rest between and above the Walzenkb'rpern lo, 11 on a plate or the like, which is on elastic elements or the like. on the side panels 14 supported (not shown) · The motor 23 moves the imbalance shafts via the gear 24 by means of belts or chains 21, 22 and the roller body Io, 11 in a synchronous Rotational movement, the unbalance shafts 21, 22 with a relatively generate vibratory oscillations in rapid succession at high speed; the revolution and thus the Forward speed of the roller body Ιο, 11 is by means of a reduction gear, not shown, greatly throttled.

Due to the unbalanced masses, which are offset to one another, an interaction in the vibration is achieved that alternates

aen lifts one roller body Io and the other roller body 11 pushes into the ground area. This pressure is generated once by shifting the weight of the roller onto a roller body and then exerted by the directed force of the storm waves 21, 22, the weight shift depending on the directed force of the unbalance shafts 21, 22.

The vibrational forces of the unbalanced shafts 21 »22 act as shock-like pressures on the axle bearings 15, which are therefore subject to a large load. In order to avoid destruction of the roller bearings 16 as a result of the permanent pressure load, the roller bearings 16 are equipped with the damping layer 17 surrounding them. Which consist of an elastic material, preferably rubber od _e like. Damping layers 17 to protect the bearings 16 from damage or destruction by intercepting dampened the vibration forces transferred lojll without strength reduction to the axes 12, 13 and thus the roll body. The mode of operation of the roller bodies lo, ll is not influenced by the damping layers 17; the functioning of the roller remains unaffected, only the roller bearings 16

The hard mounting of the roller bearings 16 is advantageous duroh the damping schioht 17 has been canceled »whereby between unbalanced shafts 21, 22 and roller bodies lo, 11 none rigid, but flexible, damped connection has been established

The damping layers can be made easier and cheaper Manufacture way and easily assemble with the rolling bearings.

It is within the scope of the Heuerurig, the damping also occurs in a different spatial shape, for example as a square or Eechteckbloofc or the like on the roller bearings and the vibrating operation of the roller body is consistently well maintained.
