Description
Technical field
The invention belongs to the bearing means technical field, relate to a kind of sliding bearing, the oval sliding bearing of especially a kind of intelligent state adjustable elastic, it is applicable to the support that radially slides that operating conditions changes in a big way.
Background technique
Sliding bearing stable working, reliable, noise free if can guarantee that fluid lubrication can significantly reduce fretting wear.Though under general operating mode, for example occasion such as lathe, speed reducer automobile is replaced by rolling bearing, in a lot of important events, still accounts for critical role as fields such as generator set, steam turbine, rolling mill, high-speed main spindles.Sliding bearing can be divided into radial sliding bearing and thrust slide bearing by its work loads that bears, and by the tile fragment form radial bearing can be divided into common circle watt (as Fig. 1 a), elliptic bush (as Fig. 1 b), heavy wool leaf (as Fig. 1 c), can incline watt (as Fig. 1 d) and misplace watt (as Fig. 1 e) etc., and thrust-bearing can be divided into fan-shaped fixing watt (as Fig. 1 f), and circle can be inclined watt (as Fig. 1 g) and fan-shaped incline watt (as Fig. 1 h) etc.Traditionally, a certain or several particular job situations that are based on these sliding bearings design, yet it is in service in actual production, the working condition of sliding bearing may need frequent variations, can be as generator set according to the difference of power consumption, adjust its working speed, for guaranteeing the safe operation of unit sliding bearing, need guarantee that unit keeps a certain stable working state, when peak times of power consumption, the in short supply of electric power resource can be caused, and waste of power resources can be caused at the electricity consumption low peak period; Equally; bearing the large-scale core key equipment of complicated impulsive load; as disintegrator; rolling mill and large-size machine etc.; acute variation may take place in work loads; its operating conditions is possible change in a very wide scope; the sliding bearing of a certain special parameter often can't satisfy the working condition of frequent variations; therefore; complex working condition gently then can cause the wearing and tearing of sliding bearing; shorten bearing life, heavy then cause tile kilning; serious accidents such as seize, in case and these nucleus equipments damage; corresponding production line will be shut down, and causes the tremendous economic loss of relevant enterprise.
Therefore develop a kind of sliding support technology that goes for the working condition frequent variations, important economic implications and realistic meaning are all arranged for enterprise and society.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of intelligent state adjustable elastic oval sliding bearing, this bearing can solve the shortcoming that existing radial sliding bearing can only be applicable to a kind of or limited several working conditions, especially go for the situation of operating conditions frequent change in a big way, and this bearing has adaptive ability.
The objective of the invention is to solve by the following technical programs:
The oval sliding bearing of this intelligent state adjustable elastic comprises the adjustable elastic elliptic sliding bearing of state and detects control loop; The elastic elliptic sliding bearing that described state is adjustable comprises following watt of the elliptic bearing and the elliptic bearing on watt of relative installation, the bottom that described elliptic bearing is following watt offers the wedge shape space of a semi open model, be filled with elastic filler matter in wedge shape space, the open end of described wedge shape space is provided with the bolt jacking system of the openings of sizes of regulating wedge shape space.
Above-mentioned detection control loop comprises first and second displacement transducer, controller and alarm, described first and second sensor becomes 90 degree to install relatively near the circumferential direction along the axle journal between under the elliptic bearing watt and the elliptic bearing on watt oval sliding bearing, and the output terminal of first and second sensor is connected to the input end of controller respectively; Controller is connected with alarm.
Above bolt jacking system comprises the vertical bolt hole of the bottom, open end that is arranged on wedge shape space and the bolt that cooperates with this vertical bolt hole.
In sum, the present invention has following beneficial effect:
1) elliptic bearing of the present invention's employing goes for a very wide working condition;
2) attitude of elliptic bearing of the present invention can automatically adjust by the elastic material that is filled in wedge shape space, reach the ovality that still can regulate bearing by manual tune bolt jacking system if regulate automatically, make bearing reach the optimal working state less than job requirement.
3) the present invention is equipped with displacement transducer on elliptic bearing, can the working state of bearing be monitored, if do not reach job requirement, can report to the police automatically;
4) whole device has the advantage of automatic adjusting and manual tune, can effectively control the situation that changes the bearing working state labile that causes owing to operating conditions.
