Specific embodiment
The purpose of the present invention is described in further detail below by specific embodiment, embodiment can not herein one by one
Repeat, but therefore embodiments of the present invention are not defined in following examples.
As shown in figure 1 and 2, it is a kind of that head is horizontally rotated based on double thrust bearing, from top to bottom including being sequentially connected
Loading plate 8, the second thrust bearing 7, head intermediate support beam 6, the first thrust bearing 5, circular bottom plate 4, shaft coupling, frame 3,
Motor 1, the motor 1 is fixed on the bottom face of frame 3, and its motor shaft connects the shaft stool 2 through frame 3, while shaft stool 2
Loading plate 8 is also connected with, the head intermediate support beam 6 is also fixedly connected with frame 3.
As shown in Figure 5 and Figure 6, described head intermediate support beam 6 sets round-meshed circular plate shaped body including center, described
Circular plate shaped body lower surface is circumferentially evenly arranged with some pillars 13 that frame 3 is fixedly connected by screw.
As shown in figure 3, described shaft coupling includes shaft stool 2, long spiro nail 9, nut 10, the shaft stool 2 is clamped-in style
Shaft coupling, includes the central through hole for the connection of clamping motor axle, the central through hole both sides of the shaft stool 2, base plate 4, holds
Support plate 8 is provided with the screw hole 12 that the long spiro nail 9 is installed for penetrating in up and down alignment respectively, and the long spiro nail 9 is sequentially passed through
Shaft stool 2, base plate 4, the first thrust bearing 5, head intermediate support beam 6, the second thrust bearing 7, loading plate 8, and by nut
10 make shaft stool 2, base plate 4, the first thrust bearing 5, head intermediate support beam 6, the second thrust bearing 7, loading plate 8 press successively
Tightly, so as to compress two thrust bearings, it is allowed to that tight fit can not be departed from.Simultaneously as the clamping motor axle of shaft stool 2, axle branch
Seat 2 is connected to the loading plate 8 of the top by two long spiro nails 9, and this causes that the rotation of loading plate 8 is directly related to motor 1, its
Rotate consistent with motor shaft rotation.So by the thrust bearing transition of two-layer, cloud platform rotation is just set directly to be driven by motor 1
