Abstract
The utility model discloses a thrust base of an actuating mechanism. The thrust base of the actuating mechanism is of a brand-new structure, and is composed of a pressure ring, plane thrust ball bearings, a binding nut, a locking bolt, a drive sleeve, a thrust base body and the like, wherein the drive sleeve is arranged in the middle of the thrust base body; the drive sleeve is conical; the inner wall of the small port of the drive sleeve is made into a thread structure; the length of the drive sleeve is the same as the height of the thrust base; base holes are formed at two edges of the drive sleeve; one plane thrust ball bearing is respectively arranged inside each base hole; the diameter of each base hole is greater than that of one plane thrust ball bearing; two outer rings of the plane thrust ball bearings are arranged inside the base holes; the two outer rings of the plane thrust ball bearings move inside the base holes; the binding nut is arranged at the edge of the small port of the drive sleeve; the binding nut locks the end face of the plane thrust ball bearing; the binding nut is fixed by the locking bolt; the pressure ring is arranged at the edge of the large port of the drive sleeve; and the pressure ring presses the other end face of each thrust ball bearing. Therefore, the thrust base of the actuating mechanism is simple in structure, convenient to use, and long in service life; and the axial force transmitted by the binding nut is increased.
Description
Affiliated technical field:
The utility model relates to a kind of device security safety cover, particularly a kind of thrust base of actuator.
Background technique:
The thrust base of actuator bears valve switch two to thrust, is delivered on shell by driving casing to thrust from the switch two of valve, generally is designed with single bearing and bears two sides thrust, easily damage, life-span is short, causes this thrust often to be obstructed, and makes troubles to the user.
The model utility content:
For the technical deficiency of existing the said goods, the purpose of this utility model just is to provide a kind of thrust base of actuator, is a kind of brand new, is comprised of trim ring, thrust ball bearing with flat seat, binding nut, Cock screw, driving casing, thrust base etc.
The technological scheme that its technical problem that solves the utility model adopts is: in the middle of the thrust base, driving casing is set, driving casing is cone shape, and the portlet inwall of driving casing is made worm structure, and the length of driving casing is the same with the height of thrust base; The driving casing both sides are provided with base holes, a thrust ball bearing with flat seat is set in every base holes, the base holes diameter is greater than the thrust ball bearing with flat seat diameter, two outer rings of thrust ball bearing with flat seat all are arranged in base holes, two outer rings of thrust ball bearing with flat seat are all movable in base holes, binding nut is arranged on the portlet limit of driving casing, binding nut fastens thrust ball bearing with flat seat one end face, fix with Cock screw on binding nut, trim ring is installed the large port limit of driving casing, and trim ring is pushed down the thrust ball bearing with flat seat other end.
The utility model beneficial effect: simple in structure, easy to use, long service life, the transmission axial force of increase binding nut.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
In figure, 1, trim ring, 2, thrust ball bearing with flat seat, 3, binding nut, 4, Cock screw, 5, driving casing, 6, the thrust base.
Embodiment:
as shown in Figure 1, the utility model is comprised of trim ring 1, thrust ball bearing with flat seat 2, binding nut 3, Cock screw 4, driving casing 5, thrust base 6, driving casing 5 is set in the middle of thrust base 6, driving casing 5 is cone shape, the portlet of driving casing 5 is made worm structure, and the length of driving casing 5 is the same with the height of thrust base 6, driving casing 5 both sides are provided with base holes, a thrust ball bearing with flat seat 2 is set in every base holes, the base holes diameter is greater than thrust ball bearing with flat seat 2 diameters, two outer rings of thrust ball bearing with flat seat 2 all are arranged in base holes, 2 two outer rings of thrust ball bearing with flat seat are all movable in base holes, binding nut 3 is arranged on the portlet limit of driving casing 5, binding nut 3 fastens thrust ball bearing with flat seat 2 one end faces, fixing with Cock screw 4 on binding nut 3, increase binding nut 3 and transmit axial force, trim ring 1 arranges the large port limit of driving casing 5, trim ring 1 is pushed down thrust ball bearing with flat seat 2 other ends, simple in structure, easy to use, long service life.
