Abstract
The utility model relates to a main machine structure of a disc eddy current dynamometer. The utility model solves the problems that an existing dynamometer machine can not detect the starting torque of a prime motor at zero speed, and the existing dynamometer machine has low testing accuracy short service life and is not suitable for the automation control of a distant microcomputer. The utility model comprises a water tank type bottom plate and an outer support member of an eddy current disc. An exciting winding and the eddy current disc are arranged on the outer support member of an eddy current disc through screws; an induction plate is sheathed on a rotary shaft in a hot mode. The non-dragging end of the rotary shaft is provided with a zero speed torque detection device composed of a left shaft coupling and a left end cover; the dragging end of the rotary shaft is provided with a cushion block, and a gap between the induction disc and the eddy current disc can be regulated.
Description
The utility model is a kind of power measurement arrangement, particularly a kind of locked-rotor torque of the rotating machinery that can detect any kind of and the commentaries on classics distance under different rotating speeds, and then can detect the main machine structure of the disc type eddy current dynamometer of its power.
Existing dynamometer such as cylindrical swirl dynamometer machine, hydraulic dynamometer can not be measured the detent torque of prime mover in zero-speed, and measuring accuracy is low, and serviceable life is short, is unsuitable for remote microcomputer robotization control.
The purpose of this utility model is, solves above-mentioned existing existing problem, provides a kind of measuring accuracy high disc type eddy current dynamometer main machine structure.
The utility model is achieved in that and the utlity model has a water tank type base plate, by the bearing seat that is installed on it the outer support member of eddy-current disc is installed, and field winding, eddy-current disc are installed on the outer support member of eddy current by screw forms armature (stator); In rotating shaft, form rotor by the formed circular inductive disks hot jacket of some long teeth, rotating shaft is fixed on the outer support member of eddy-current disc by Bearing Installation, eddy-current disc is made up of two smooth disks, the water flowing of mazy groove energy is all being opened at the back side of disk, so that the long-pending heat of eddy current generation is cooled off.The non-end that drags in rotating shaft is installed the zero-speed survey torque means of being made up of Left-wing Federation's axial organ and left end cap.Support member top is provided with rising pipe outside eddy-current disc, is provided with water inlet pipe in the bottom; At the cushion block that is equipped with that drags end of rotating shaft, can adjust the gap between inductive disks and the eddy-current disc.
Advantage of the present utility model is that simple and compact for structure, the measuring accuracy height is installed zero-speed survey torque means at the non-end that drags, and also can measure the detent torque of prime mover in zero-speed.Can realize microcomputer robotization control at a distance.
Fig. 1 is a structural representation of the present utility model;
Fig. 2, Fig. 3 are the structural representation of left end cap;
Fig. 4, Fig. 5 are the structural representation of Left-wing Federation's axial organ;
Describe in detail below in conjunction with accompanying drawing:
As shown in the figure, the utlity model has a water tank type base plate 9, by the bearing seat 10 that is installed on it the outer support member 5 of eddy-current disc is installed, field winding 4, eddy-current disc 6 are installed on the outer support member 5 of eddy current by screw forms armature (stator); By formed circular inductive disks 3 hot jackets of some long teeth in rotating shaft 7, rotating shaft 7 is fixed on the outer support member 5 of eddy-current disc by Bearing Installation, eddy-current disc 6 is made up of two smooth disks, and the water flowing of mazy groove energy is all being opened at the back side of disk, so that the long-pending heat of eddy current generation is cooled off.The non-end that drags in rotating shaft 7 is installed the zero-speed survey moment device of being made up of Left-wing Federation's axial organ 1 and left end cap 13.Support member top is provided with rising pipe 2 outside eddy-current disc, is provided with water inlet pipe 11 in the bottom; Rotating shaft 7 drag end cushion block 12 is housed, can adjust the gap between inductive disks 3 and the eddy-current disc 6.The end that drags in rotating shaft 7 is installed shaft coupling 8, connects tested device by shaft coupling 8.
