A device and method for fixation of bone fractures has a bone screw comprising a shank with a threaded end portion, on the outer surface. The screw has a through bore with two bore portions differing in diameter. A step in the diameter is formed between these bore portions and is located within the end of the screw having the thread. This step in diameter can support a metal insert which in turn supports a polymer pin when the latter if pressurized with a sonotrode in the bone screw. Together with an applied ultrasonic vibration the pressure fluidizes the polymer pin and presses the material through holes configured in the wall of the bone screw and into surrounding bone.

A pulley includes a radial rolling bearing and a pulley main body which are integrated to each other by an insert molding method. Therefore, a metal insert member is not required between the resin pulley main body and the radial rolling bearing, thereby reducing production cost of the pulley. Further, an axial dimension of an outer ring of the radial rolling bearing is set larger than an axial dimension of an inner ring thereof, so that a contact area between the radial rolling bearing and the pulley main body is increased. Therefore, a connection strength between the radial rolling bearing and the pulley main body is increased, and a surface area of the radial rolling bearing is increased, thereby improving heat radiation performance of the radial rolling bearing.

The invention discloses a fully mechanized caving top coal caving three-dimensional simulation experiment platform and an experiment method. The platform and the method are used for researching the influences of elements in coal mine fully mechanized caving working face, such as mining-caving ratio, caving manner, caving technology, bracket tail beam inclination angle, coal caving port size, and broken top coal particle sizes, upon fully mechanized caving working face top coal recovery rate, and for verifying the influence of the spatial arrangement of an onsite top coal tracker upon onsite actual measurement precision of top coal recovery rate. According to the experiment platform provided by the invention, a mobile immediate roof is arranged, such that the influence of roof caving during an experiment process upon the recovery rate can be avoided. Coal pillars are preserved on the boundary, and only central-area recovery rate is counted, such that the influence of experiment method boundary conditions upon recovery rate statistics can be basically eliminated. Experimental-area residual coal amount can be obtained by using sheet metal inserts, such that top coal recovery rates under different conditions can be obtained. Therefore, guidance can be made for actual engineering, and an optimal fully mechanized caving scheme can be selected.

A molded polymeric bearing housing is formed of a moldable polymer base material in combination with a glass fiber reinforcing component. A foaming agent is added to the base material to create a fine structural foam within interior regions of the housing. A density gradient is established between regions adjacent to the surfaces of the housing and the internal regions, thereby reducing the need for reinforcing ribs particularly in a base or mounting portion of the housing. An antimicrobial agent may be added to the housing material to inhibit the growth and proliferation of fungi, molds, bacteria, and so forth. Structural features of the housing may be formed subsequent to the molding process, such as by turning operations. Metal inserts may be provided to avoid crushing of regions of the housing, such as by attachment fasteners. The housing forms a mounting base surface in a single plane coextensive with the footprint of the housing. When the housing is placed in service moisture and debris is prevented from collecting below the housing by conformity of the mounting base surface with the machine support surface. The housing may be formed in a variety of styles, including pillow block styles, tapped base pillow block styles, two and four bolt flange styles, take up frame styles, flange bracket styles and so forth.
