Abstract
The utility model relates to a guide shoe base of a hydraulic turbogenerator guide bearing, and is characterized in that: the exterior side of the arcuated guide shoe casting part is produced with a groove, and the inner side of the guide shoe casting parts is inlaid with segmental bearing alloy; a rectangle shoe base is installed in the groove through a channel insulation pad and an insulation washer and a woven glass fabric tube, and the center of the shoe base is installed with a blind hole for installing a spherical surface support nail, and the blind hole inner lining is equipped with a chrome steel pad, moreover an eccentricity e is between the groove and the arcuated guide shoe base casting part, and the chrome steel pad in the blind hole is integrated with the shoe base. Along with pivoting motion of the machine unit rotating large shaft, the guide shoe endlessly produces swinging at the radial direction, thereby augmenting over flow of the friction surface, effectively reducing friction of the guide shoe and temperature increase, and improving bearing capacity of the guide shoe, in addition, the chrome steel pad in the blind hole and the shoe base are produced in an integration, thereby eliminating loosening problem produced by non-ideal combinion of the chrome steel backing surface or guide shoe base bottom face or expanding problem of the guide shoe clearance, and improving stability; in addition, the utility model also has the advantages of simple structure and easy manufacture.
Description
Technical field
The utility model relates to the guide shoe seat of Hydraulic generator pilot bearing.
Background technique
The design of vertical hydrogenerator guide bearing at present is general adopts anti-heavy screw to support the conventional construction of piecemeal guide shoe: promptly outer side surface is shaped on the arc guide shoe foundry goods of groove, be inlaid with the segmental bearing alloy at guide shoe foundry goods inner side surface, by channel insulation pad and insulating washer and glass stringing rectangle watt seat is installed in groove, watt seat center is shaped on the blind hole of mounting spherical support pin (anti-heavy screw), is lined with the chromium steel pad in the blind hole.The advantage of this structure is to be convenient to install and adjust.But shortcoming is the be in operation guide shoe gap of guide bearing to be strengthened gradually, causes the main shaft throw to increase, unit vibration, and bring out the generation of other accident.Directly jeopardize the safe operation of unit.Therefore, for the safe operation of unit, the power station is had in the interval of overhaul to increase and is adjusted the guide shoe gap, reduces the maintenance at ordinary times of throw, and also needing of having repeatedly adjusted.This not only causes the economic loss that reduces generated energy, but also has increased the weight of the workload of maintenance.In recent years, in order to overcome the anti-defective that heavily supports the piecemeal guide shoe, the design of Hydropower Unit has both at home and abroad adopted the diclinic wedge-type to adjust the new structure in guide bearing block gap.This structure is preventing aspect watt crack expansion certain effect is arranged, but that it exists manufacture cost is higher, and so the defective of install, maintenance is inconvenient is also generally employing so far.Domestic and international newly-designed unit major part still adopts anti-heavy screw to support piecemeal guide shoe conventional construction now.And the problem of guide shoe gap enlargement still exists.
Summary of the invention
The utility model provides the guide shoe seat of the Hydraulic generator pilot bearing in a kind of effective control guide shoe gap for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of guide shoe seat of Hydraulic generator pilot bearing, comprise that outer side surface is shaped on the arc guide shoe foundry goods of groove, is embedded in the segmental bearing alloy of guide shoe foundry goods inner side surface, is installed in rectangle watt seat in the groove, blind hole that watt seat center is shaped on the mounting spherical support pin and the blind hole by channel insulation pad and insulating washer and glass stringing and is lined with the chromium steel pad, the middle bisector plane of the middle bisector plane of described groove and arc guide shoe seat foundry goods has an eccentric distance e, and the chromium steel pad in the described blind hole is made one with a watt seat.
The utility model can also adopt following technological scheme:
Described eccentric distance e approximates 2% of arc guide shoe foundry goods bearing metal radius of arc R.
Advantage and the good effect that the utlity model has are:
Because the middle bisector plane of groove and the middle bisector plane of arc guide shoe seat foundry goods have an eccentric distance e, like this, rotate the swing of macro-axis along with unit, guide bearing block constantly produces rocking of warp-wise, can increase the inflow-rate of water turbine of guide shoe attrition surface thus, reduce the friction and the temperature rise of guide shoe effectively, improve the bearing capacity of guide shoe, in addition a chromium steel pad in the blind hole and a watt seat are made one, eliminate rebasing of chromium steel or guide shoe seat bottom surface in conjunction with the undesirable loosening or guide shoe gap enlargement problem that produces, improved stability; The utility model also has advantage simple in structure, that be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1.
Among the figure: 1, bearing metal; 2, guide shoe foundry goods; 3, channel insulation pad; 4, watt seat; 5, insulating washer; 6, glass stringing; 7, screw; 8, packing ring; 9, groove; 10, insulating washer; 11, chromium steel pad; 12, blind hole.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1 and Figure 2, outer side surface is shaped on the arc guide shoe foundry goods 2 of groove 9, be inlaid with segmental bearing alloy 1 at guide shoe foundry goods inner side surface, by channel insulation pad 3, insulating washer 5, insulating washer 10 and glass stringing 6 rectangle watt seat 4 is installed in groove, watt seat center is shaped on the blind hole 12 of mounting spherical support pin, is lined with chromium steel pad 11 in the blind hole.The middle bisector plane of the middle bisector plane of described groove and arc guide shoe seat foundry goods has an eccentric distance e, and this eccentric distance e approximates 2% of arc guide shoe foundry goods bearing metal 1 radius of arc R; Chromium steel pad in the described blind hole is made one with a watt seat.Like this, along with the swing of unit rotation macro-axis, guide bearing block constantly produces rocking of warp-wise, can increase the inflow-rate of water turbine of guide shoe attrition surface lubricant oil thus, reduces the friction and the temperature rise of guide shoe effectively, improves the bearing capacity of guide shoe; In addition a chromium steel pad in the blind hole and a watt seat are made one, eliminated rebasing of chromium steel or guide shoe seat bottom surface, improved stability in conjunction with the undesirable loosening or guide shoe gap enlargement problem that produces; The utility model also has advantage simple in structure, that be easy to make in addition.
