Title: Rotational displacement measuring instrument
Inventor: KATSUKURA MIKIMOTO
IPC: G01B11/26
Filed: 1989-02-17
Abstract: PURPOSE:To enlarge a range where the rotational displacement can be measured even if a rotating body rotates by returning a beam reflected with a plane mirror on the same optical path again and advancing it in the direction of a beam splitter and a beam bender, and leading it to an interference detector. CONSTITUTION:Plane mirrors 7 and 7' are provided on the optical path of a beam reflected by a measuring mirror 5 and a reference mirror 4, and also, provided vertically to the optical path. A beam from a laser element 1 is split in the direction to the measuring mirror 5 and a beam bender 2 by a beam splitter 6, and the light beam going to the beam bender 2 is further reflected to the reference mirror 4 therein. Thereafter, the light beam which is reflected with the measuring mirror 5 and the reference mirror 4 and reaches the plane mirrors 7 and 7' is reflected thereby and returns on the same optical path, and deflected in the direction of an interference detector 8 with the beam splitter 6 and the beam bender 2. Accordingly, even if a rotating body 3 rotates, the reflected beam from the measuring mirror 5 and the reference mirror 4 is inputted to the interference detector 8 without being displaced, therefore, the measuring range of a minute rotational displacement can be enlarged.

Abstract: PURPOSE:To easily discharge grease further prevent its leakage, by forming a slinger in a large external diameter while inserting felt between a fixed part and a rotary part so as to decrease a clearance between a bearing cover and the slinger. CONSTITUTION:Increasing the external diameter of a slinger 2 while decreasing a clearance between the slinger 2 and a bearing cover 1, felt 7 is inserted between the bearing cover 1 and the slinger 2. In this way, the discharging power of grease caused by centrifugal force increases while the slinger 2 approximates to about a discharge port 6, decreasing discharge resistance of the grease, thus facilitating its discharge. While the grease, whose reverse flow is prevented, can be prevented from its leakage from the discharge port 6.
