Title: Constant velocity joint
Inventor: YOKOYAMA KENZO
IPC: F16D3/2245
Filed: 1994-11-02
Abstract: PURPOSE: To obtain a constant velocity joint having the low heat generation by using a grease having the low friction for the lubrication at each contact point between a ball, outer coupling member and an inner coupling member and specifying the two-dimensional nipping angle formed by each tangential line on the coupling center surface at each contact point. CONSTITUTION: A constant velocity joint is constituted of an outer coupling member 1 having the first guide groove 15, inner coupling member 2 having the second guide groove 23, cage 3 set between both the coupling members 1 and 2, and balls 4. An urea group grease having the low friction is used for the lubrication at the contact point (e) between the first guide groove 15 and the ball 4 and at the contact point (m) between the second guide groove 23 and the ball 4. The two-dimensional nipping angle αn formed by the tangential line on the coupling center surface at the contact point (e) and the tangential line on the coupling center surface at the contact point (m) is set as follows: 11.3 deg.<=αn <15 deg..  Since the dynamic frictional coefficient μ is reduced by the urea group grease, the two-dimensional nipping angle αn can be reduced in comparison with the range of the designed value in the SAE excitation, and the cage load between the cage 3 and the ball 4 can be reduced, contributing to the low heat generation.

IPC: G01S13/50
Filed: 1991-10-18
Abstract: PURPOSE:To enable identification of a target approaching at a speed higher than a set value simultaneously with detection of target signals by generating a high speed target detection signal when the difference between signal distance measured values is larger than a distance corresponding to the set speed. CONSTITUTION:Target signals received by an antenna 1 are passed to a receiver 2 and converted into digital values by an A/D converter 3 and long pulses are switched by a switching circuit 4 to a video integrator 6a through a pulse compressor 5 and short pulses are switched directly to an integrator 6b. The distance to a target is calculated by first and second range finders 8a, 8b and input to a comparator 9. Then the circuit 4 performs switching action in response to a switching signal that a modulation signal generator 16 generates when half of the dwell time elapses. A transmitter 15 thus feeds to the antenna 1 transmission signals which are modulated from a frequency modulation signal for the long pulse of the first half of the dwell time from the generator 16 and an amplitude modulation signal for the short pulse of the second half of the dwell time. The comparator 9 generates a high speed target detection signal according to conditions.
