Detailed description of the invention
Embodiment 1
Rotary drilling rig upper-part rotation driving rotary encoder of the present invention, as shown in Figure 1: be now to test get off ring support 1 and with
The anglec of rotation between the getting-on platform 3 that ring support 1 concentric shafts of getting off rotates, described in get off ring support 1 diameter with getting-on platform 3
The biggest, and be in the environment of closing.
One internal-gear type revolving support, the ring gear 2 of revolving support and ring support 1 of getting off are installed on the ring support 1 of getting off of rotary drilling rig
Fixing, the external toothing of revolving support is fixed with getting-on platform 3, opens a shoulder hole, use spiral shell in shoulder hole on getting-on platform 3
Clenching solid installing plate 5, equipped with encoder mounting seat 6 on installing plate 5, rotary encoder 7 is arranged on encoder by bolt and installs
On seat 6, rotary encoder 7 power shaft is connected with power transmission shaft 9 by bellows coupling 8, and power transmission shaft 9 passes through rolling bearing
10 and bearing block be arranged on installing plate 5, power transmission shaft 9 upper end is provided with step surface and contacts with upper end rolling bearing 10, to biography
Moving axis 9 carries out axial limiting, it is to avoid the axial force of shaft coupling is excessive, prevents case accident, and the outer ring of rolling bearing 10 is equal
Being furnished with circlip for hole 11 to position, travelling gear 12 is arranged on the end of power transmission shaft 9, in order to ensure travelling gear 12 and pass
Moving axis 9 does not produces relative rotation, and introduces flat key 13, and uses hex nut 14 to lock travelling gear, at power transmission shaft
9 end split pins 15 are spacing, prevent the part being arranged on power transmission shaft 9 to be scattering in oil sump, cause adverse consequences.It is anti-
Only dust enters in oil sump by encoder, arranges O-ring seals 4 on installing plate 5.
Above-mentioned internal-gear type revolving support is as primary drive and bearing carrier, described ring gear 2 and the gear drive of external toothing
For low-speed heavy-loaded gear transmission, use the closed-type gear transmission of 8 class precisions, can be helical gears, it is possible to for herringbone bear,
Can also be spur gear wheel, said gear transmission uses oil sump lubrication.
The transfer principle of said structure is, when platform rotates, getting-on platform 3 rotates an angle, θ relative to ring support 1 of getting off, with
Get off the fixing ring gear 2 connected of ring support 1 (such as tooth number Z1=99) angle, θ is also rotated, ring gear 2 band nutating gear 12 (as
Tooth number Z2=8) θ is rotated1, i.e. travelling gear 12 drives power transmission shaft 9 rotational angle θ1, power transmission shaft 9 is by bellows coupling 8
The power shaft that encoder 7 is rotated rotates, this angle, θ1Sent to control system, it is achieved angle number by anglec of rotation encoder
The collection of the number of it is believed that, is understood θ by gear ratio1=99/8=θ, it is achieved getting-on platform 3 often revolves when turning around, encoder 7 defeated
Enter axle and rotate 12.375 circles, it is achieved the accurate measurement of angle.
Rotary drilling rig upper-part rotation driving rotary encoder is gear drive, and the modulus of travelling gear 12 is identical with ring gear, passes
Dynamic ratio is constant, and data transmission will not be little because of bang path generation loss measurement angular error, and precision is high, travelling gear 12 and transmission
The detachable structure of axle 9, simple in construction, save material, location standard.
Embodiment 2
Opening a shoulder hole on getting-on platform 3, a bearing block is made into integration with described installing plate 5, installs transmission in bearing block
Axle 9 and rolling bearing 10, aperture is installed bearing block, the cylindrical of bearing block and the aperture interference fits of shoulder hole, is passed through shoulder hole
The perpendicularity of step surface positioning bearing seat central axis, power transmission shaft is major diameter in bearing block, and bearing block top is exposed
Part use minor diameter, be connected by shaft coupling with rotary encoder.
The advantage of above-mentioned mounting structure is, can the perpendicularity of axis of positioning bearing seat, it is ensured that travelling gear 12 and ring gear 2
The accuracy of mesh.
Other structures are same as in Example 1.
Embodiment 3
Embodiment 1-2 is all that minor diameter planet pinion 9 engages with the ring gear 2 of major diameter, the two different axis, as
Fruit uses the interior travelling gear 9 of major diameter, and coaxial line rotates, then the center that can omit is misaligned and the conversion error that produces.
Rotary drilling rig upper-part rotation driving rotary encoder has stable work in work, and maintenance cost is low, it is achieved that in closed-loop
Border is measured the angle of revolution of the different objects that concentric shafts rotates, there is the feature that precision is high, the simultaneously center of inside engaged gear
Away from little, compact conformation, be suitable to the structure design of small space.
Travelling gear 12 uses self-lubricating material to make, and such as engineering plastics, case-hardening alloy steel, will not pollute because of phenomenon of getting rusty
Lubricating oil in oil sump.
