Abstract

The equipment with the output pulsating force contains unbalanced rotating bodies, geared transmissions and a frame where are rotary mounted two carriers with the parallel axes. There is rotary mounted at least one pair identical unbalanced rotating bodies (1) on the each carrier (3). They are mutually linked with a geared transmission (4,5) so that they rotate in an opposite direction but with an equal angular velocity (;ω) and with an opposite phase of the position of the centre of gravity (T) of the unbalanced rotating body. The carriers are mutually linked by a geared transmission or by another method for achieving a mutual opposite rotation with an equal angular velocity (;ω) and with the mutual opposite phases. The output force is the result of the linked movement of the rotating bodies. During the rotation the position of the all unbalanced rotating bodies is identical respectively mirror identical. The height of the position of the centre of gravity of the all unbalanced rotating bodies above the rotating axis of the carrier is equal in the all angles of turning of the unbalanced rotating bodies. At the same time, the angle of turning of the carrier is identical with the angle of turning of the unbalanced rotating bodies.

Description

Equipment with the output pulsating force

Technical Field

The invention is a device where the pulsating force is created mainly from the input rotating moment on its output.

Background Art

There are some devices known that create a pulsating force in different directions from the input rotating moment. For example, vibration boards for compacting of building mixtures or drives of jolting machines that use a pair of eccentrically mounted shafts. There is created a centrifugal force by the rotation of eccentrically mounted shafts which vector rotates identically with the rotation of the centre of gravity of the unbalanced mass. There can be achieved a process of created forces corresponding to the vector sum by the engagement of few eccentrically mounted shafts. The drawback of this equipment is a contrarious course of the output force.

Disclosure of the Invention

The mentioned disadvantage can be eliminated with a device with the outlet pulsation force that contains unbalanced rotating bodies and a frame according to this invention. The principle of this invention consists in such the construction where two rotary carriers embedded in the frame have the same mass and the same moments of inertia and their axes are parallel. There is embedded minimally one pair of unbalanced rotating bodies in each carrier whose axis of rotating pass perpendicularly through the axis of the carrier. The unbalanced rotating bodies have the same mass, the same moments of inertia, and the equal distance of their centres of gravity from the axis of rotation. The each pair of the unbalanced rotating bodies is linked together with a geared transmission so that the unbalanced rotating bodies embedded on one carrier rotate in opposite direction with an equal angular velocity ω and with the opposite phase of position of the centre of gravity T of an unbalanced rotating body. The carriers are linked together with a geared transmission or with another method for the reason of achieving of rotation in opposite direction by an equal angular velocity ω and for the mutual opposite phases of the location of the rotating planes of the unbalanced rotating bodies on a carrier. With this arrangement there can be achieved a condition where the position of the all unbalanced rotating bodies in the initial time is equal. In the initial position, the axes of the unbalanced rotating bodies of the two carriers are parallel and equal. During the rotation, the position of the all unbalanced rotating bodies is identical respectively mirror identical and in the same time the height of the position of the centre of gravity of the all unbalanced rotating bodies above the axis of rotation of the carrier in the all positions of turning of the unbalanced rotating bodies is equal. In the same time, the angle of turning of the carrier is identical with the angle of turning of the unbalanced rotating bodies. The identical angular velocities of rotation of the unbalanced rotating bodies and the mutually opposite phase of position of their centres of gravity cause the status that the components of the centrifugal forces in the direction parallel with the axis of rotation of the carrier are mutually compensated in force within the carrier and from the carrier there are transferred only the radial forces without the axial force components to the frame. Mutually opposite and equally fast rotation of the unbalanced rotating bodies causes that the gyroscopic moments developed by a synchronised rotating of the carrier are mutually compensated in the embedding of the rotating bodies on the carrier.

For the construction simplicity, it is favourable if an identical angular velocity of rotating ω of the unbalanced rotating bodies and of the carriers is provided with a mechanical transmission. It is beneficial if the transmission is made with geared wheels.

There is attached a tapered geared wheel to the axis of rotation of just one unbalanced rotating body that interlock into another tapered geared wheel on the axis of the carrier that is firmly fitted with the frame. The transmission ratio of this gearing is 1:1. The other option of the mutual coupling of the unbalanced rotating bodies and carriers is to use independent drives or motors for the particular rotating bodies. The management of these drives or motors is mutually linked. It is favourable for balancing of the rotating masses of the geared transmissions and for the mutual elimination of the gyroscopic moment without any bending stress on the carrier if the equipment, according to this invention, has two pairs of the unbalanced rotating bodies at the each carrier on the two parallel axes. The both of the unbalanced rotating bodies with the identical rotating axes have mounted a tapered geared wheel located at the opposite ends of the carrier. The both tapered geared wheels interlock into a common tapered geared wheel that is firmly attached to the frame. There is achieved a reversible rotation of the unbalanced rotating bodies with the identical rotating axis with this arrangement. The gyroscopic moments, which are created by the rotation of the carrier at the rotation of the unbalanced rotating bodies, are mutually compensated within their common axes. The carriers and the all unbalanced rotating bodies rotate with an identical angular velocity ω. In relation to this, there comes to the elimination of the all factors of the forces in the axes x and y and of the created moments at their opposite rotation. The final pulsating force has direction in the axis z.

The mutual linkage of rotation of the unbalanced rotating bodies can be made indirectly with tapered gears so that the each rotating body is linked with a tapered geared wheel that interlocks into a non-rotating tapered geared wheel on the axis of rotation of the carrier. The unbalanced rotating bodies have not to be directly linked with the geared transmission at such the arrangement and can have a shape more suitable for achieving of a bigger unbalance. In a suitable arrangement, the non- rotating tapered geared wheel can have an adjustable element for the adjustment and arrestment of the rotating position against the casing. By this, there can be achieved the adjustment of the exact mutual angular position of the unbalanced rotating bodies.

For the decreasing of the resistance of the rotating bodies and of the carriers, it is favourable if the frame is made by a hermetic case that is designed for making an internal vacuum while the vacuum in the case can be permanent or can be created during the operation of the device.

The equipment with the output pulsating force according to this invention can be equipped with a splinter-proof cover from the safety reasons. The equipment according to this invention is equipped with a linkage element for linkage with and for a transfer of the output force to the driven body or equipment. It is beneficial if such the linkage element e.g. a joint is located on the casing in such the way that it allows the three-dimensional angular change of the position of the casing against the position of the driven body or equipment. By this arrangement there is obtained an option to change the direction of the output force developed by the equipment of this invention.

The equipment gains the option to change the direction of the output force developed by the equipment of this invention.

Brief Description of Drawings

The invention is further described in more details on the drawings. On the Figure No. 1 there is drawn the equipment in the section going through the axes of the carriers showing the output pulsating force in the construction with the unbalanced rotating bodies mutually linked with a front face gears. On the Figure No. 2, there is drawn a longitudinal section through a carrier. On the Figure No. 3, there is drawn the equipment in the section showing the output pulsating force in the construction with the unbalanced rotating bodies mutually linked with a tapered gearing attached to the casing. There is drawn a carrier in the longitudinal section on the Figure No. 4. On the Figure No. 5 there is shown the kinematic scheme of the arrangement of the particular equipment elements with the output pulsating force that is applicable for the both constructions arrangements.

Example 1

The equipment with the output pulsating force according to the Figure 1 and 2 is created with the casing 2 and with the system of the two carriers 3. There are mounted two pairs of the unbalanced rotating bodies 1 on the each carrier 3. The status being out of balance of the rotating bodies is achieved by the taking off some of the material from the part of the mass of the rotating body 1. They also fulfil the function of the geared wheels for the mutual rotating linkage of the unbalanced rotating bodies 1. The rotating linkage of the carrier 3 and the unbalanced rotating body I is achieved with the two tapered geared wheels 4 and the tapered geared wheel 5 with the transmission ratio 1 : 1 while the tapered geared wheel 5 is firmly attached to the frame 2. The axes of the carriers are equipped with the front face mutually interlocked geared wheels 6 of the transmission ratio 1:1.

Example 2

The equipment with the output pulsating force according to the Figure No. 3 and 4 has the tapered geared wheels 4 mounted on the axis of the each unbalanced rotating body I which is different from the example 1. The unbalanced rotating bodies 1 are mutually rotary indirectly linked by the system of the tapered geared wheels 4 and 5 where the tapered geared wheels 5 are firmly attached to the frame 2. The tapered geared wheels 5 mounted on one side of the frame 2 are fitted with an arrestment and positioning element that allows the adjustment of the rotating position of the tapered geared wheel 5 against the frame 2 for the adjustment of the correct mutual phase of the particular movable bodies and for the determination of the tooth clearance of the gear transmissions. For the decreasing of the torsion deformations, there are located the gear transmissions 6 between the carriers 3 on the both sides of the casing 2.

Industrial Applicability

The utilization of this equipment is apparent. According to this invention there is possible to industrially manufacture equipments with an output pulsating force mainly for the drives of the transport and manipulation machinery.
