Gear bond tester

The radial bound of the gear ring △Fr, within one rotation of the gear, the testing header is in the grooves or on the gear, and touch the both sides of the high and middle part of the groove, and the testing header shall point to the axle of the gear. Therefore, the radial bound inspection is performed according to the testing header of original shape of the groove. The sketch shows the theory indication of this tester. During the test, fix the tested gear installed on the axle between the two probes of the tester, and insert the testing headers with original groove shape into the grooves of the gear in order. Then the bound status of the testing header to the rotation axle of the gear shall be indicated.
It is used for inspecting the radial bound or end surface bound of columns, taper outer groove engaging gears and worm wheels and worms whose accuracy is at level 6 or below.

Granite precistion bench center

I. Usage:

It is widely used for measuring the axial and disk products and parts, and mainly inspecting their radial bound, ellipticity and end surface differences.

II. Advantages:

1. Adopts granite instrument stand, and thus increases the accuracy of benchmark plane and decreases the self accuracy difference of the instrument.

2. The movable indicator stand of the gauge can be placed to any part of the indicator stand to perform measurement.

3. The indicator stand shall never get rusted, and is convenient to be used and kept.

III. Way of use:

Tighten the handle of the eccentricity axle, and fix the finial stand. Fix the moveable finial stand at the appropriate position according to the length of the tested part.Press down the ball head handle, put the part in, and fix the part with the two probes through the hole in the center of the part.Tighten the tightening handle, and fix the finial.Adjust the moveable stand of the gauge at the required position, and the inspection can be performed with coordination of the dial indicator (clock gauge).

IV. Accessory: One set of moveable stand of the gauge.

New type of bench center

It is equipped with a pair of Morse No.4 finials, which improves the measuring accuracy of the bench center and increases the support strength to the tested parts. It can measure the radial, end surface and bevel bound of precise parts. The design of the indicator stand is delicate and reasonable, and it can be easily adjusted to all directions. The rigidity of the indicator stand is high, and thus the sensitivity of the testing instrument is improved.

Main technique parameters:

Normal type: The accuracy of the radial rotation is 0.003mm.

The parallelism between the side leading track and the link of the two finials is 0.005mm (A03, B03 type), 0.008mm (A05, B05 type), 0.02mm (A10, B10 type).

The max diameter of the tested part is 250mm.

The max lengths of the tested part are 300mm, 500mm, 1000mm.

High precision bench center

It is equipped with a pair of Morse centers of 4# rigidness, which escalates the measuring precision and increases the support strength on measured parts. It can be used for the radial run-out, end run-out and tilting circular run-out. The design of the meter stand is deliberate and reasonable, and it can be adjusted easily to all directions. The operation is easy and the rigidness of the meter stand is good, which improved the delicacy of the instrument. It is especially suitable for the measurement of grinded parts.

Main parameters:
(1) Radial rotating precision: 0.001mm;
(2) Parallelism the side guideway on the span and the link line of the two centersL 0.005mm (type I), 0.007mm (type II), 0.002mm/100;
(3) Maximum diameter of the tested part: 250mm;
(4) Maximum length of the tested part: 500mm, 800mm.

The XW-250 type multi-function measuring instrument for testing differences of shape and position

The instrument is fixed with the finial support, and under the coordination of data collecting and processing equipment, it can measure 8 kinds of shape and position differences of the axial parts and disc/sleeve parts, including roundness, column roundness, coaxality, axes, straightness, cable-line straightness, cable-line parallelism, circular bound (radial, end surface, bevel), and radial full bound.
