Each point along the axial screw surface is tangentially wiped by the other screw with a constant relative velocity. for simplicity, consider the screw simply as a flat disc as shown in figure 2. if disc 1 is held stationary, disc 2 with rolling circle radius am2 rolls off the base circle with the radius m1a of disc 1.

Although screw oil press has been used for more than 100 years in oil extraction industry, it is still one of the main machines of oil processing industry and widely used in major oil production enterprises. however, with the continuous development of oil industry, the defects of traditional screw oil press are protruding, especially for some special volatile oil plants.
Tension in the screw exceeding the tensile strength and break-ing of the screw. on the other hand, if the screw is completely dry of lubricant the clamping force might be too small to withstand the forces for which the joint is designed, with the risk that the screw becomes loose. table 1. friction in threads of different material.
If this seems small, keep in mind that the ultimate strength breaking strength of a grade 2 bolt is 74 ksi, so a 6 screw could theoretically hold 672 lbs in pure tension. if youre wondering why bolts you see in cars and weight machines are so large, its partly to guard against loosening and fatigue failure in addition to safety factors.
Depending on flywheel size, very high energy can be generated with this type of drive. press tonnage is from 200 to 1,600, with a two-point connection to the slide. a double-geared press drive is good for transfer die work. transfers typically run at 15 to 30 spm. presses with this drive normally are rated 0.500 in. from bdc to bdc.
The basics of shoulder-screw grades, dimensions, materials, and options can help designers get the best product for their applications.
