Title: Screw rotor tooth form
Inventor: KASUYA KATSUHIKO
IPC: F04C18/16
Filed: 1985-03-04
Abstract: PURPOSE:To obtain the screw rotor tooth form which is insensible to the influences of the manufacturing error of the rotor and assembly error, etc. by forming the advance surface flank of a female rotor tooth form so that the deflection from the fundamental tooth form continuously increases towards the tip part and the bottom part from the min. pressure angle point. CONSTITUTION:As for the advance-surface flank 5 of a female rotor tooth form 1, the min. pressure angle point 20 is positioned on the fundamental tooth form, when a pair of rotor tooth forms meshed free from the clearance shown by the full line is used as the fundamental tooth form. Towards the tip side and the bottom side from the point 20, the deflection from the fundamental tooth form is represented as the corrected tooth form which continuously increases as shown by the dotted line. In other words, the deflection from the fundamental tooth form is directed in the direction for reducing the tooth thick ness. Therefore, the screw rotor tooth form which is hardly given with the influence of the manufacturing error in rotor tooth form, assembly error, etc. and insensible to precision can be obtained. Therefore, the tooth contact in the vicinity of the min. pressure angle point 20 on the advance surface flank for the certain transmission of revolution torque can be secured.

Abstract: PURPOSE:To reduce whirling of a spindle hub due to the change of temperature to reduce the occurrence of data error by coupling only a part of the outside peripheral surface of one ring to the inside peripheral surface of the other ring by press-fitting and forming a gap in the other part. CONSTITUTION:A ring A39 which has the inside peripheral surface brought into contact with outer wheels of bearings 37 and 38 and is made of a material whose coefficient of thermal expansion is approximately equal to that of outer wheels of bearings and a ring B40 which has the outer peripheral surface brought into contact with the center hole of a magnetic disk 34 and is made of a material whose coefficient of thermal expansion is approximately equal to that of the magnetic disk are fitted to each other to form a spindle hub 36. Only a part of the outer peripheral surface of the ring A39 is coupled to the inner peripheral surface of the ring B40 by press- fitting, and a gap is formed in the other part. Since the hub 36 consists of two parts, namely, the ring A39 and the ring B40 and they are coupled only in a part of the span in the axial direction and they are not coupled in the other part because of the gap in this manner, the difference of expansion in the radial direction due to thermal expansion is absorbed as the variance of the binding margin of the coupling part, and the gap functions as an escape in the axial direction to reduce the mutual interference due to expansion.
