Embodiment Construction

[0012] Below the present invention is described in further detail, see figure 2 , image 3 .

[0013] A high-precision hand-operated low-speed turntable for angular displacement detection, including gear A1, key 2, rotating shaft 3, spring 4, screw 5, pinion 6, handle 7, damper 8, digital display 9, grating code Gear 10, gear B11; the number of teeth of gear A1 and gear B11 is the same as the modulus, and the staggered teeth pass through the rotating shaft 3 and are installed closely to form a double-plate gear. The screw 5 axially passes through gear A1 and gear B11 for preliminary positioning , the gear A1 is connected with the rotating shaft 3 through the key 2, the symmetrically arranged spring 4 is installed in the circumferential direction, one end is installed on the gear A1 and the other end is tensioned on the gear B11; the handle 7 can drive the pinion 6 to rotate, and the lower end has The damper 8 eliminates the transmission gap through the meshing of the pinion...

Abstract

The invention is used for angular displacement detection, can be used for measuring linearity and gradient of a potentiometer, a synchronizer, a gyro and other products, and particularly relates to a high-precision hand-cranking low-speed rotating table. Present hand-cranking low-speed rotating tables use a worm gear-worm rod pair drive structure and are low in ruling precision, and the highest resolution is greater than 1 degree; besides, the worm gear and the worm rod are complex in machining, and precision is difficult to guarantee, which brings about poor zero return precision of a zero position mark, poor repeatability and high cumulative error when a rotating shaft moves along clockwise and anticlockwise directions in a reciprocating way and thus brings higher error to angular displacement measurement. The invention provides the high-precision hand-cranking low-speed rotating table which is simple in structure, high in single-stage rotating speed ratio, high in drive ratio and low in assembling difficulty. Rotating angular displacement measurement precision is high, production and manufacturing cost is low, assembling and debugging are simple, maintenance is convenient and rotation is steady and reliable so that the application of the rotating shaft under the condition of high load can be realized.

Description

technical field [0001] The invention is used for angular displacement detection and can measure the linearity and gradient of products such as potentiometers, synchronizers and gyroscopes, and specifically relates to a high-precision hand-operated low-speed turntable. Background technique [0002] The current hand-operated low-speed turntables all adopt the worm gear-worm pair transmission structure (such as figure 1 ), a 360-degree indexing line 13 is made on the end face of the worm wheel 16 along the circumference, and together with the housing marking line 12, the working angle of the turntable is indicated. Combining the secondary transmission structure of the worm wheel 16 and the worm screw 17 itself with the characteristics of self-locking and large single-stage speed ratio, turning the handle 7 can make the worm wheel 16 rotate smoothly along the clockwise and counterclockwise, so that the key 14 and the rotating shaft 15 can be realized at low speed, applications ...
