Abstract
The utility model discloses ball-screw-transmission assembly, bearing nut (10) is through thrust-bearing (9), O type circle (13) is arranged on the bottom of bearing support (8), through bearing cap screw (7) rigid bearing cap (6) on the top outer wall of bearing support (8), the top of bearing cap (6) is through the fixing seat of honour (1) of seat of honour screw (2), through the fixing screw rod bushing (4) of screw rod bushing screw (5) on the top inwall of bearing support (8), screw rod bushing (4) internal thread connection wire rod (3), bottom organizine pole cap (11) of screw mandrel (3) is fixed on the inwall of bearing nut (10), screw mandrel cap (11) organizine pole cap screw (12) is fixed on bearing nut (10), overall formation ball-screw-transmission assembly.The utility model structure is simple, with low cost, and valve by lead screw transmission, reduces the moment of torsion of valve, reduces friction in opening and closing, laborsaving, saves time.
Description
Technical field
The utility model relates to the driving mechanism of Open valve and throttle down, is specifically related to a kind of ball-screw-transmission assembly.
Background technique
At present, the opening and closing of valve mainly carry out transmission by the connection of screw thread, and this kind of drive exists following problem: one is the male thread of valve rod and the box thread connection for transmission of valve plate, and contact friction force is large, brings moment of torsion large; Two is that valve rod screw thread and valve plate screw thread are easy to wear, shortens the working life of valve; Three is when high pressure and large bore valves, and a people can not open valve, depend on 2-3 people, could by valve open, and the opening and closing of valve are required great effort very much; Four is that need the time long, transmission efficiency is low when valve opening and closedown, and labor intensity is large, easily there is potential safety hazard.
Summary of the invention
The purpose of this utility model is: provide a kind of ball-screw-transmission assembly, valve by lead screw transmission, reduces friction in opening and closing, laborsaving, saves time.
Technical solution of the present utility model is: this drive assembly comprises the seat of honour, seat of honour screw, screw mandrel, screw rod bushing, screw rod bushing screw, bearing cap, bearing cap screw, bearing support, thrust-bearing, bearing nut, screw mandrel cap and screw mandrel cap screw, bearing nut is through thrust-bearing, O type circle is arranged on the bottom of bearing support, through bearing cap screw rigid bearing cap on the top outer wall of bearing support, the seat of honour is fixed through seat of honour screw in the top of bearing cap, the top inwall of bearing support fixes screw rod bushing through screw rod bushing screw, screw rod bushing internal thread connection wire rod, the bottom organizine pole cap of screw mandrel is fixed on the inwall of bearing nut, screw mandrel cap organizine pole cap screw is fixed on bearing nut, overall formation ball-screw-transmission assembly.
Wherein, bearing nut installs lubricating cup.
During installation, the bottom of screw mandrel is connected with the valve rod upper end A CME male thread of valve by ACME box thread, and the T-shape slot of the stem bottom of valve is connected with the T-shape slot of valve plate; During transmission, screw mandrel rotates up and down, and the valve plate of band movable valve moves up and down, thus Open valve and throttle down.
The utility model has the advantages that: 1, the pitch of screw mandrel is large, it is 3 times of common leading screw pitch, the time of Open valve and throttle down just shortens 4 times, effectively controls the time opening and closing valve when high pressure, protects the safety of equipment and the person; 2, the transmission of screw mandrel greatly reduces the moment of torsion of valve, and the friction factor of screw mandrel and screw rod bushing transmission is very little, makes the common valve of the torque ratio of valve alleviate 2/3, improves the working life of valve.
