Abstract
The invention provides a screw type torque self-loading device. Trapezoidal threads are formed on the inner surface of a pipe wall of a shell. The shell is connected with a control tube through the trapezoidal threads in a threaded mode. A flat key groove is formed in one side of an inner hole of the control tube, and the flat key groove is connected with an input shaft in a sliding and matched mode through a guide key. A guide boss extends out from the left side of the inner hole of the control tube. The guide boss is connected with a screw guide groove formed in an output shaft in a clearance fit mode. The butt joint portions of the output shaft and the input shaft are connected through a push-and-pull bearing. The butt joint axial distance between the output shaft and the input shaft is determined according to the distance between step shafts on the shafts and the end caps arranged at the two ends of the shell. The portion, extending out of one end cap of the shell, of the output shaft and the portion, extending out of the other end cap of shell, of the input shaft are respectively provided with a flange. A plurality of countersinks are formed in the outer cylindrical surface of the shell in the circumferential direction. The outer cylindrical surface of the shell and a friction sheet control mechanism are connected in a matched mode. The screw type torque self-loading device is easy to machine, convenient to install and detach, small in size, light in weight, and capable of being used reliably for a long time.

summary of the invention:
In order to meet the moment of torsion of high speed, high-power gear drive blocking test platform, load requirement, improve the loading efficiency of gear drive blocking test platform, the invention provides a kind of torque loading device for High Speed Gearing blocking test platform.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: spiral moment of torsion bootstrap loading device, comprise housing, housing inner surface of tube wall has acme thread, housing is threaded with control tube by acme thread, control tube endoporus one side has between flat key groove and input shaft by feather key sliding connection, a guide ledges is extended in the endoporus left side of control tube, between guide ledges and the spiral guide slot of outputing on output shaft, clearance fit is connected, output shaft is connected by push-and-pull bearing with input shaft butted part, the axial distance of output shaft and input shaft docking is determined by the distance between the Step Shaft on axle and the end cap at housing two ends, output shaft and input shaft stretch out housing end plug and are partly respectively equipped with flange, housing outer cylinder surface circumferencial direction has some counterbores, housing outer cylinder surface and friction disc control gear are connected.
The present invention has following beneficial effect: the processing of this device is simple, easy installation and removal, volume are little, lightweight, can use stably in a long term.
accompanying drawing explanation:
Fig. 1 structural representation of the present invention.
1-output shaft in figure, 2-control tube, 3-housing, 4-push-and-pull bearing, 5-friction disc control gear, 6-feather key, 7-input shaft, 8-counterbore, 9-gathering sill, 10-acme thread, 11-guide ledges.
Embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, spiral moment of torsion bootstrap loading device, comprise housing 3, housing 3 inner surface of tube wall have acme thread 10, housing 3 is threaded with control tube 2 by acme thread 10, control tube 2 endoporus one sides have between flat key groove and input shaft 7 by feather key 6 sliding connections, a guide ledges 11 is extended in the endoporus left side of control tube 2, between guide ledges 11 and the spiral guide slot 9 of outputing on output shaft 1, clearance fit is connected, output shaft 1 is connected by push-and-pull bearing 4 with input shaft 7 butted parts, the axial distance of output shaft 1 and input shaft 7 docking is determined by the distance between the Step Shaft on axle and the end cap at housing 3 two ends, output shaft 1 and input shaft 7 stretch out housing 3 end caps and are partly respectively equipped with flange, housing 3 outer cylinder surface circumferencial directions have some counterbores 8, housing 3 outer cylinder surfaces and friction disc control gear 5 are connected.
Input shaft 7 is connected with blocking test system by two end flanges with output shaft 1, between input shaft 7 and output shaft 1, by control tube 2, be connected, power passes to output shaft 1 by input shaft 7 by control tube 2, during roll-shell 3, can realize the axially-movable of control tube 2, feather key 6 between control tube 2 and input shaft 7, restriction control tube 2 can only move axially along input shaft 7.Control tube 2 is when axially-movable, the guide ledges 11 of control tube front end is moved along output shaft spiral guide slot 9, spiral guide slot 9 on output shaft is arranged at an angle on output shaft 1 surface, like this at control tube 2 simultaneously in axial sliding, output shaft 1 circumferentially has certain rotation, can realize the axially-movable of control tube 2 when roll-shell 3.
Housing both sides are circumferentially with spanner interface, and manual wrench is inserted in counterbore 8, rotate backward housing 3, and housing 3 drives control tube 2 drawback movements by acme thread 10, and output shaft 1 reverse rotation is by the moment of torsion unloading loading.
Clockwise transmission when loader is seen from input end (right side), drives control tube 2 rotations by feather key 6 when input shaft 7 rotates, and control tube 2 drives output shaft 1 rotation by spiral guide slot 9, realizes power transmission.
Static loading process: input shaft 7 maintains static, manual wrench is inserted in counterbore 8, (from input end) roll-shell 3 counterclockwise, housing 3 drives control tube 2 to move to input end along axial direction by acme thread 10, when control tube 2 moves, guide ledges 11 is moved along gathering sill 9, drive output shaft 1 to clockwise rotate, system is loaded.The distance that the angle loading is moved by angle and the control tube 2 of spiral chute 9 determines.
Dynamic load process: during the clockwise transmission of whole loader, control 5 pairs of housings 3 of friction disc mechanism and apply certain friction force, make housing 3 and input shaft 7 produce speed discrepancy, control tube 2 is synchronizeed rotation with input shaft 7, therefore housing 3 has generation speed discrepancy with control tube 2, by screw thread, control tube 2 is moved towards input end, and then drive spiral guide slot 9 to rotate, output shaft 1 relative input shaft (7) is rotated and realize loading, loading velocity is by the decision of friction force size, and the large loading velocity of speed discrepancy that friction force makes greatly control tube 2 and housing 3 produce is just fast.
Uninstall process: when system experimentation is complete need to unload moment of torsion time, manual wrench is inserted in counterbore 8, (from input end) roll-shell 3 clockwise, housing 3 drives control tube 2 drawback movements by acme thread 10, and the relative input shaft 7 of output shaft 1 is rotated counterclockwise the moment of torsion loading is unloaded.
The more traditional charger structure compared of this charger is compact simple, and dynamic balance easy to process is better, can be applied in higher rotating speed blocking test.
