Specific embodiment
Describe in detail below in conjunction with the accompanying drawings and to specific implementation method.
Such as Fig. 1, a kind of unidirectional loading running in machine of planetary roller screw pair, including the servomotor for sequentially coaxially connecting 1st, left coupling 2, torque sensor 3, right screw mandrel 8, bearing 4, leading screw 5, nut 6, sleeve 7, hanging bolt 9;The two of sleeve 7 End-stopping plate is supported by two cylindrical linear rails 14 parallel to workbench respectively;Pacify between cylindrical linear rail 14 and workbench Equipped with linear displacement transducer 13;One end of rope 11 is tied up on hanging bolt 9, and the other end bypasses pulley 10 and hangs counterweight group 12;Servomotor 1 is connected by left coupling 2 with torque sensor 3;Torque sensor 3 passes through right screw mandrel 8 and the phase of leading screw 5 Even;Servomotor 1 is fixedly connected on the table by support frame 15;Pulley 10 is fixedly connected on workbench end;Support frame 15 grades are fixed in the T-slot of workbench by T-bolt.
The two axial ends of torque sensor 3 pass through left coupling 2 and the shaft end of servomotor 1 and the shaft end phase of leading screw 5 respectively Connection, the moment of torsion and tachometer value of the detection output of servomotor 1.
Linear displacement transducer 13 uses grating scale;Grating scale is made up of motion block and quiet guide rail two parts, motion block and sleeve 7 It is fixed together, quiet guide rail is fixedly connected on the table;Grating scale can detect the stationarity of motion and the jump of acceleration Rise and pulse, realize the measurement and the detection of running-in abrasion condition to positioning precision under planetary roller screw pair working condition.
Two end-stopping plates of sleeve 7 are supported by two cylindrical linear rails 14 parallel to workbench respectively;Not only play fixation The effect of connection, also avoids leading screw 5 that fine rotation or mobile phenomenon occur, it is ensured that planetary roller screw pair running-in and loading examination The accuracy and operability of experiment device.
Cylindrical linear rail 14 is fixed on the table by the baffle plate at the two ends of sleeve 7;Not only support is played to sleeve 7 to make With also guide sleeve 7 drives nut 6 reciprocating, and movement locus is even deviated from so as to prevent sleeve 7 to be shifted over, and detects The transmission efficiency and kinematic accuracy of planetary roller screw pair, with excellent reliability.
Counterweight group 12 is fabricated structure, different by multiple thickness, the close mass composition of profile;By counterweight group 12 The increase and decrease of quantity detects the size of the loading force that planetary roller screw pair can bear, and realizes visualization and the behaviour of loading size Make high-speeding.
