Step 2: removing all testing gears and multiple deviation drive devices are circumferentially uniformly installed, so that all yaws are driven
The yaw driving gear of dynamic device is engaged with the yawing gear ring；And then adjust each yaw driving yaw driving gear with
The backlash of the yawing gear ring is consistent.
The installation method of above-mentioned external tooth type yaw system, wherein in step 1, be uniformly arranged in the circumferential direction on mainframe
Four testing gears.
The installation method of above-mentioned external tooth type yaw system, wherein in step 1, by diagonal sequence successively adjustment yaw tooth
The backlash of circle and four testing gears.
The installation method of above-mentioned external tooth type yaw system, wherein in step 1, pass through the adjustment bolt on yaw clamp
Adjust the backlash of the yawing gear ring Yu the testing gears.
The installation method of above-mentioned external tooth type yaw system, wherein in step 2, pass through the eccentric disc of deviation drive device
Adjust the backlash of yaw the driving gear and the yawing gear ring.
The installation method of above-mentioned external tooth type yaw system, wherein in step 2, yaw driving gear and it is described partially
The backlash of boat gear ring is adjusted to 0.48mm~0.8mm.
The installation method of above-mentioned external tooth type yaw system, wherein in step 2, yaw driving gear and it is described partially
The backlash of boat gear ring is adjusted to 0.60mm~0.65mm.
Compared with the existing technology, the invention has the following advantages:
The present invention realizes reliable, stable and adjustable yawing gear ring installation, proposes one kind and possesses compensation way twice

Fig. 2 is the partial enlargement diagram of Fig. 1；
Fig. 3 is the structural schematic diagram of existing deviation drive device.
Specific embodiment
Below in conjunction with attached drawing, by specific embodiment, the invention will be further described, these embodiments are merely to illustrate
The present invention is not limiting the scope of the invention.
The present invention provides a kind of installation methods of external tooth type yaw system comprising following steps:
Step 1: (being divided place circumference as shown in Figure 1, being uniformly arranged in the circumferential direction four testing gears 1 on mainframe
For the quartering)；Installation yawing gear ring 2 simultaneously engages it with the testing gears 1, realizes the positioning of yawing gear ring 2, it can be ensured that
Yawing gear ring 2 is substantially concentric with 4 testing gears 1；By the adjustment bolt 4 on yaw clamp 3 by diagonal sequence successively adjustment
The backlash of yawing gear ring and four testing gears 1 is simultaneously consistent and (adjusts for the first time), tentatively ensures yawing gear ring 2 and all surveys
It is concentric to try gear 1；Specifically, as shown in Fig. 2, making it by rotating above-mentioned adjustment bolt 4 to adjust the exposed length of bolt
Yawing gear ring 2 is withstood to be adjusted.
Step 2: as shown in figure 3, removing all testing gears 1 and circumferentially uniformly installing multiple deviation drive devices, making
The yaw driving gear 5 for obtaining all deviation drive devices is engaged with the yawing gear ring 2；And then pass through the inclined of deviation drive device
The backlash that cartridge adjusts yaw driving gear 5 and the yawing gear ring 2 that each yaw drives is consistent (second of tune
It is whole), it is ensured that yawing gear ring 2 is concentric with all deviation drive devices；Specifically, yaw driving gear 5 and eccentric disc connect
It connects, eccentric disc can change the center of circle of yaw driving gear 5 by rotating eccentric disc relative to yaw drive motor bias.It is excellent
The backlash of selection of land, the yaw driving gear 5 and the yawing gear ring 2 is adjusted to 0.48mm~0.8mm；It is highly preferred that described
The backlash of yaw driving gear 5 and the yawing gear ring 2 is adjusted to 0.60mm~0.65mm.
The final installation of yaw clamp 3 is finally carried out, above-mentioned adjustment twice can make the deviation from circular from for yawing clamp 3 exist
0.10mm is hereinafter, the concentricity of deviation drive device and yawing gear ring 2 in 0.03mm~0.05mm, completes yaw system
Installation.Since backlash is close, each deviation drive device is almost consistent with the field of conjugate action of yawing gear ring 2, makes Load Balanced, will not
Unbalance loading phenomenon is generated, the service life of product is improved.
In conclusion the adjustment at center is carried out to yawing gear ring by adjusting twice, it is ensured that yawing gear ring and all yaws
The concentricity of gear is driven, while also ensuring the circularity of yaw clamp, yawing gear ring and yaw in the course of work is reduced and drives
Engagement load between moving gear, greatly improves service life；Installation for the external tooth type yaw system of plane caliper brake,
This method can be used to be installed, there is great demonstration.
The present invention realizes reliable, stable and adjustable yawing gear ring installation, proposes one kind and possesses compensation way twice
Yawing gear ring mounting means, greatly improve the installation accuracy and tooth engagement degree of yawing gear ring, while improving yawing gear ring
Service life.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
