Abstract
The utility model provides an adjustable water turbine generator bearing sealing drapes, which comprises an outer ring attached with a radial inner ring slot provided with an inner ring composed of a plurality of arc segment bodies with each of the arc segment body positioned with a limit hole respectively at two ends. The outer ring corresponding to the limit hole is provided with an axial direction bolt extends into the hole; a spring is respectively arranged on back arc face of each of the arc segment body, which is fixed through the bolt. The utility model adopts multi arc segment body traveling inner ring sealing structure and enables the inner ring radial sealing surface to track the radial motion of the rotating shaft automatically by utilizing the action of the spring to each arc segment body, which compensates the gap created by moving, vibrating and wearing of the inner ring, so as to realize the good sealing.
Description
Technical field
The utility model relates to mechanical seal structure, is a kind of adjustable hydraulic turbine generator bearing seal retaining specifically.
Background technique
Aluminium tooth or the labyrinth sealing of copper tooth are generally adopted in the bearing seal of hydraulic generator unit, and its structure is radially to inlay aluminium or copper tooth on the annular groove to form inner ring body and constitute in the inboard of outer ring body.Because the hydraulic generator unit diameter of axle is bigger, rotor operation speed is low and the beat amount is big, and the ring assemblage gap can not be too little in causing, otherwise cause vibration easily, and axle is caused wearing and tearing.Because the wearing and tearing of the oval running orbit of rotor shaft to ring in sealing are added in the existence of assemblage gap, unit operation after a period of time sealing effect reduce, leakage of oil occurs, advance problem such as ash, have a strong impact on the normal operation of generator set.
Summary of the invention
The purpose of this utility model is at the problems referred to above, a kind of adjustable hydraulic turbine generator bearing seal retaining is provided, and it adopts the gear piece mounting structure that moves about, and can regulate automatically according to the radial motion situation of rotor shaft and follow the tracks of the gap variation, ring remains with axle and contacts in making, and realizes excellent sealing.
The technological scheme that realizes above-mentioned purpose is: a kind of adjustable hydraulic turbine generator bearing seal retaining, it includes with the outer ring body of inner groove radially, the radially annular groove of outer ring body is provided with the inner ring body of being made up of a plurality of segmental arc bodies, its two ends of forming each segmental arc body of inner ring body are respectively arranged with spacing hole, the axial bolt that is provided with corresponding outer ring body with spacing hole stretches in its hole, is respectively arranged with the spring through screw on the convex surface of each segmental arc body.
The utility model adopts ring structure in the multi sphere segment body swimming type, by the effect of spring to each segmental arc body, in making the ring radial sealing surfaces from the radial motion of motion tracking rotor shaft, to motion and vibration and in the gap that produces of ring wearing and tearing compensate, all the time keep in touch with axle, realize excellent sealing.
Description of drawings
Fig. 1 is this adjustable hydraulic turbine generator bearing seal retaining plan view;
Fig. 2 is the A-A profile of Fig. 1.
Embodiment
Embodiment describes embodiment of the present utility model in conjunction with the accompanying drawings:
Provide as accompanying drawing, this adjustable hydraulic turbine generator bearing seal retaining has with the outer ring body 1 of inner groove radially, and this outer ring body can adopt multistage to connect and compose, and its inner groove is arranged on the both sides of outer ring body radial section, and the centre of two annular grooves is provided with the transition annular groove.Both sides at outer ring body radially are equipped with the inner ring body of being made up of a plurality of segmental arc bodies 2 on the inner groove, the two ends of each section segmental arc body are respectively arranged with the long-round-shape spacing hole, the corresponding screw 3 that is fixed with axial setting on outer ring body through screw-thread fit with each spacing hole, the front portion of its screw is stretched in the spacing hole of segmental arc body.On the convex surface of each segmental arc body, be respectively arranged with the spring of fixing through screw 45.Its spring 5 can adopt the wire spring or the leaf spring of V-arrangement, excellently when specifically implementing makes curved leaf spring, and the number that its spring is provided with is determined according to the length of the diameter of axle and segmental arc body.The spring that is arranged at two ends can adopt the spring structure of half V-arrangement and half arc, to avoid interference mutually between two-phase short round spring.
Claims (2)
1, a kind of adjustable hydraulic turbine generator bearing seal retaining, include with the outer ring body of inner groove (1) radially and be assemblied in the inner ring body of forming by a plurality of segmental arc bodies (2) on the inner groove, it is characterized in that: the two ends at each segmental arc body of forming inner ring body (2) are respectively arranged with spacing hole, corresponding outer ring body with spacing hole (1) is provided with axial bolt (3) and stretches in its hole, is respectively arranged with on the convex surface of each segmental arc body through the fixing spring (5) of screw (4).
2, adjustable hydraulic turbine generator bearing seal retaining according to claim 1, it is characterized in that: the described spring (5) that is arranged at segmental arc body convex surface is curved leaf spring.
