According to the all-dimensional planetary ball mill with the directly-connected speed reduction motors, the unique structure and principle of the speed reducers are utilized, original additional tension force and eccentric force are reduced, and meanwhile the size can be decreased; therefore, the effects of reducing abrasion, reducing noise and prolonging the service life are achieved.

The invention provides a lifting rib device for a washing machine, a washing machine having the same, and a control method thereof, wherein the lifting rib device includes a base, a rotating assembly, a telescopic assembly and a lifting rib, and the base is arranged on the inner wall of the inner cylinder of the washing machine; the rotating assembly and the telescopic assembly Under the action, the lifting ribs rotate along the circumferential direction of the inner cylinder and move radially; Clothes position, the weight detection device detects the weight of the clothes in the clothes storage position, and transmits the weight to the washing machine controller, and then the controller controls the movement of the rotating component and telescopic component of the lifting rib device, breaks up the clothes and moves them to the adjacent clothes storage In the position, the weight of clothes in each storage position is similar, avoiding large vibrations caused by uneven distribution of clothes during the dehydration process of the washing machine; the invention has simple structure, high degree of automation, uniform distribution of clothes, and stable operation of the dehydration program of the washing machine.

The invention discloses a gas static pressure bearing with a floating thrust surface. The gas static pressure bearing comprises a bearing body, a bearing lining, a floating thrust surface body and an elastic plate, wherein the bearing body sleeves the bearing lining; one end of the bearing body is connected with one end of the elastic plate in a sealing manner; the other end of the elastic plate is connected with the floating thrust surface body in the sealing manner; the elastic plate and the floating thrust body are connected with one end, in the axial direction, of the bearing body in sequence; a plurality of gas holes which are communicated in a matched manner are formed in the bearing body, the elastic plate and the floating thrust body; the elastic plate is made of an elastic material. According to the technical scheme, the thrust surface is changed to be in a floating type structure, so that a gas film clearance between the gas bearing and a shaft body is uniform, eccentric force of the bearing is reduced, and the axial bearing capacity of the gas bearing is greatly improved; and therefore, the gas bearing can be used for bearing a high axial load and achieving the high flow and the high rotating speed.

The invention discloses a solid-stone bare-rock riverbed trestle used for the deepwater high-pier long-span bridge construction and a construction method thereof. The trestle includes a trestle body and a horizontal work platform located on the front side of the trestle body. The trestle body includes a lower-portion support structure, a main beam and a bridge deck; the lower-portion support structure includes one or more steel abutment anchoring piles, the lower portions of the steel abutment anchoring piles are anchored to a bare-rock riverbed, the front end of the main beam is supported ona steel cofferdam, the rear end of the main beam is supported on a shoreside surpport platform, and a concrete pumping pipe is placed on the bridge deck; the horizontal work platform is set up on thesteel cofferdam and is connected with the main beam, and each steel abutment anchoring pile includes a groined steel abutment and a steel abutment anchoring structure. The method includes the steps of1, construction of the steel abutment anchoring piles, 2, erecting of the main beam and 3, paving of the bridge deck. The solid-stone bare-rock riverbed trestle is reasonable in structural design, easy to construct and good in use effect, the steel abutment anchoring piles are stably supported on the bare-rock riverbed, the front end and rear end of the main beam are supported on the steel cofferdam and the shoreside support platform respectively, and labor and time are saved.

The invention provides a radial radiation-type rotational filter screen disc and a preparation method thereof. The radial radiation-type rotational filter screen disc comprises an internal rim and an external rim; a radial radiation-type filter screen which is uniformly distributed along the circumference and formed by winding a filter screen wire is arranged between the internal rim and the external rim; two axes center pressing covers are fixedly buckled to the positive surface and the reverse surface of the internal rim; and the center of the axes center pressing cover is provided with a shaft sleeve matched with the output shaft of a motor. The preparation method comprises the following steps of: firstly fixing the front end of the filter screen wire on the internal rim and leading thefront end to attach to the positive surface of the internal rim closely and enwind at the corresponding radial points of the external rim; subsequently leading the front end to closely attach to thereverse surface of the external rim, return in original route and enwind at the adjacent points of the internal rim; rotating the external rim by an angle; subsequently leading the filter screen wireto attach to the positive surface of the internal rim and enwind at another radial corresponding point of the external rim; repeatedly carrying out the above operations till all filter screen wires are uniformly weaved by one ring; and subsequently fixing the tail end of the filter screen wire on the external rim and finally using the two axes center pressing covers to clamp the internal rim fromthe positive surface and the reverse surface. The method has the advantages of good running stability and balance performance, high efficiency of intercepting dust and granules and long service life.
