Abstract
The utility model relates to a testing tool for keyway dimension of a tangential key. The testing tool is characterized in that the testing tool comprises one slide block and a dial indicator, one end of the slide block is provided with a hole, the thickness of the slide block is identical with the width of the tangential key, and the dial indicator is provided with a magnetic pedestal and is adsorbed on the slide block. The testing tool provided by the utility model has the advantages of high installation precision of the tangential key, simple operation and convenient usage.
Description
Technical field
The utility model relates to a kind of testing tool, specifically the testing tool of tangential key keyway size.
Background technology
Tangential key are a kind of forms of key connecting in the mechanical drive, are characterized in being comprised of the wedge key that two gradients are 1:100.Its upper and lower surface is workplace, and one of them face is in passing through the plane of axial line.Pressure on the workplace can transmit very large torque along the tangential direction effect of axle, and tangential key connect that to be mainly used in load very large, and centering requires not tight occasion, connects by tangential key with the furnace shell backing ring such as the tiling arrangement of steelwork converter.This connects the in design intensity of principal security tangential key, and General Requirements has the rational magnitude of interference, the heavy load moment that is produced to satisfy the running of plant equipment both forward and reverse directions.For this reason, how the assembly quality of key and keyway reaches designing requirement, very large to serviceable life and the production function of plant equipment.
Summary of the invention
The utility model is intended to overcome the defective of prior art, and a kind of testing tool of tangential key keyway size is provided, and can prevent that installation accuracy is inadequate, and is easy to operate.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of testing tool of tangential key keyway size is characterized in that, comprises a slide block and dial gauge, and an end of described slide block has the hole, and the thickness of slide block is identical with the width of tangential key; Described dial gauge is attached together with magnetic bases and with slide block.
The beneficial effects of the utility model are: prevent the gap, installation accuracy is high, and is simple to operate, the convenient use.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of tangential key.
Fig. 2 is the schematic diagram that step b determines the detection position in the detection method of tangential key keyway size.
Fig. 3 is the structural representation of slide block.
Embodiment
As shown in Figure 1: a kind of detection method of tangential key keyway size may further comprise the steps:
A. the inspection of keyway, measurement and grinding
When wheel hub and axle are not nested together, check the keyway workplace of tangential key with leveling ruler, adopt coloring method respectively to linearity, flatness and the contact point inspection of keyway, also comprise and adopt leveling ruler or tangential key as the reference field grinding of fitting;
As shown in Figure 2:
B. determine the detection position
The tangential key 1 that comprise paired use, every pair of tangential key are by two wedge keys 11,12 form, two wedge keys are placed up and down and are located in the keyway, top wedge key is moving key 2, following wedge key is dead key 3, after wheel hub 6 assembles with axle 7, make the keyway of a pair of tangential key be in the below of axle horizontal direction together, make whole wheel hub supported vertically by gap 4 on the gear wheel axis hole with the weight of plant equipment, make the wheel hub deadweight that is enclosed within on the axle be fitted in the top of axle journal, be in lower gap 5 on the shaft length direction to eliminate upper gap 4, and guarantee axially to contact fully, make the below that is in the axle center of lower gap 5 natures;
C. use type steel support
In order to prevent the keyway dislocation between axle and the wheel hub, support in the relevant position by adopting shaped steel, and measure the width of keyway of wheel hub both sides and the width of keyway of axle both sides with micrometer inside caliper, make its both sides width consistent, error is controlled at 0.1mm;
D. check the depth of parallelism of tangential key keyway workplace
As shown in Figure 3, a kind of testing tool of tangential key keyway size comprises a slide block 31 and dial gauge 32, and an end of slide block 31 has hole 33, and the thickness of slide block 31 is identical with the width of tangential key 1; Dial gauge 32 is attached together with magnetic bases and with slide block 31.Respectively micrometer inside caliper and above-mentioned testing tool are filled in the keyway, measured the broadside of two keyways, namely workplace checks whether its both sides are parallel;
Between two wedge keys of every pair of tangential key and the contact area between the workplace of the workplace of tangential key and keyway should by said method, adopt this testing tool to detect and can prevent the gap greater than 70%, installation accuracy is high, and is simple to operate, convenient use.
