AN ESSAY ON PISTON RINGS ... This type of scraper usually has the same radial thickness as a pressure ring, but is wider to accommodate the slots and associated grove. ... Only where the step width has to be less than 1/3 of the axial ring width would I consider the slotted (or drilled) type. However, there is an important proviso.

The flank angle is the angle between a flank and the perpendicular thread axis. Flank angles are sometimes termed "halfangle" of the thread, but this is only true when neighboring flanks have identical angles; that is, the threads are symmetrical. Unified screw threads have .

In load [1,9]. ... an inner ring, an outer ring and seven balls. A radial external load of 5000N is applied on inner ring. The geome
Metal Rolling Metal Extrusion Metal Drawing Sheet Metal Powder Processes Metal Swaging Metal swaging or radial forging involves the forging of a work piece by use of die that exert compressive forces by impacts that act around the work's circumference. In manufacturing industry, swaging is usually performed as a cold working process.
Tapered roller bearings contain an inner ring, outer ring, and a number of tapered rollers. Looked at individually, the inner and outer bearing rings are also tapered, resembling a cone segment. Due to the large surface area contact, tapered roller bearings are able to withstand heavy axial and radial loads.
Axial deformation of the ring during the traditional vertical hot ring rolling (VHRR) process has a considerable effect on the ring products' quality. In this paper, the ring's axial deformation of VHRR process of three different rolling modes, that is, opendie mode, closedie mode and opendie mode with conical rolls like the radialaxial ring rolling (RARR) process is analyzed.
The axial section line of the ring forging is the key parameter to measure whether the ring forging process meets the technical requirements. To ensure the quality of the ring forgings, an online measuring method of the axial section line in ring forging process is proposed in this study. First, the axial section line data of the ring forging is obtained online by laser scanning device.
Ring radialaxial rolling technology is the best method to produce high quality large seamless ring. The reliable finite element model of large ring radialaxial rolling process is established. Based on the computing result of the FE model, the deformation of large ring radialaxial rolling process is studied.

Abstract. An accurate prediction of the ring diameter growth rate of a large Lsection ring during radialaxial ring rolling (RARR) by a shape axial roll is quite essential because it determines the stability of the process and thus influences the quality of the rolled ring.
Introduction The rotation of a fast moving disc or cylindrical member can set up axial, circumferential and radial stresses. For instance, in the turbine section of an aircraft gas turbine engine, the rotor disc frequently turns at speeds in the region of 10000
Fullcomplement bearings employ the maximum possible number of rolling elements, whereby the radial load is shared by a greater number of contacts and thus leads to greater load rating. These bearings can be used as a sup porting bearing like an NJ design be cause they also feature three lips.

radial and thrust load, which uses radial and thrust integrals introduced by Sjoväll; and for ball bearings under combined radial, thrust, and moment load, initially due to Jones. When an external load is applied to one of the rings of a rolling bearing it is transmitted through rolling elements to the other ring.
Prediction of radial forming force utilizes a literature model based on slip line theory adapted to the ring rolling process. To extend the validation of the approach and to explore the quality of its predictions to other process configurations, different geometry of the ring have been considered and compared with FEM predictions.
