Abstract
The utility model discloses a kind of fan yaw driving devices; it include the motor and speed reducer being connected; the output pinion of the speed reducer is meshed with the yaw bearing of blower; wherein; one shaft coupling is installed between the speed reducer afterbody sun wheel shaft and output pinion; the torque setting value of the shaft coupling is arranged according to the yaw system of blower, set the rear shaft coupling can the release when torque transfinites, achieve the purpose that protect yaw bearing and output pinion.The utility model passes through between speed reducer afterbody sun wheel shaft and output pinion plus by way of shaft coupling; when the load of speed reducer afterbody output is greater than shaft coupling setting load; shaft coupling unclamps automatically; speed reducer afterbody is contacted with output pinion disengagement, achievees the purpose that protect output pinion and yaw bearing inner ring.Compared with tradition increases frequency converter, the cost of the present apparatus is low, occupied space is few, and does not need the participation of master control, simple and reliable for this.
Description
Technical field
The utility model relates to the technical fields of fan yaw driving, refer in particular to a kind of fan yaw driving device.
Background technique
Known in the industry, traditional fan yaw driving device includes motor 01 and speed reducer 02 (as shown in Figure 1), motor 01
Drive speed reducer 02 with certain revolving speed and torque, output realizes blower to wind and the function of untying the mooring rope to yaw bearing 03.Due to
The factors such as wind load, yaw driving unbalance loading, if processing is inappropriate, are easy for slowing down when yaw driving output torque is excessive
The case where output pinion 021 of machine 02 is broken or 03 gear teeth of yaw bearing are broken, current main processing mode are to add frequency conversion
Device, but the shortcomings that this sample loading mode is that at high cost, effect is bad.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, propose a kind of safe and reliable fan yaw drive
Dynamic device, realizes the effective protection to yaw bearing and output pinion by increasing shaft coupling.
To achieve the above object, technical solution provided by the utility model are as follows: a kind of fan yaw driving device, including
There is the motor and speed reducer being connected, the output pinion of the speed reducer is meshed with the yaw bearing of blower, wherein in institute
State one shaft coupling of installation, the torque setting value of the shaft coupling between speed reducer afterbody sun wheel shaft and output pinion
According to the yaw system of blower be arranged, set the rear shaft coupling can the release when torque transfinites, reach protection yaw axis
Hold the purpose with output pinion.
The utility model compared with prior art, have the following advantages that with the utility model has the advantages that
To solve the problems, such as that fracture or the fracture of yaw bearing tooth occur for output pinion, propose in speed reducer afterbody
The mode for adding shaft coupling between sun wheel shaft and output pinion, when the load of speed reducer afterbody output is set greater than shaft coupling
When determining load, shaft coupling unclamps automatically, and speed reducer afterbody is contacted with output pinion disengagement, reaches protection output pinion
With the purpose of yaw bearing inner ring.Compared with tradition increases frequency converter, the cost of the present apparatus is low, occupied space is few, and is not required to for this
The participation of master control is wanted, it is simple and reliable.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of conventional fan deviation drive device and yaw bearing.
Fig. 2 is the structural schematic diagram of utility model device.
Fig. 3 is the simplification figure of Fig. 2.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
Shown in referring to figs. 2 and 3, fan yaw driving device provided by the present embodiment includes the motor 1 being connected
With speed reducer 2, wherein install a shaft coupling between the speed reducer afterbody sun wheel shaft 21 and output pinion 22
23, the torque setting value of the shaft coupling 23 is arranged according to the yaw system of blower, and setting the rear shaft coupling 23 can be
Release when torque transfinites achievees the purpose that protect yaw bearing and output pinion, concrete condition as follows:
When torque is greater than the torque that shaft coupling 23 is set, shaft coupling 23 unclamps, and the speed and torque of speed reducer 2 cannot lead to
It crosses output pinion 22 and passes to yaw bearing, avoid the damage of output pinion 22 or the fracture event of the yaw bearing gear teeth in this way
The generation of barrier.
When the torque that afterbody sun wheel shaft 21 exports is less than the torque of shaft coupling setting, motor 1 passes through speed reducer 2
Normal driving yaw bearing makes cabin angle change.
Embodiment described above is only the preferred embodiment of the utility model, and the implementation of the utility model is not limited with this
Range, therefore all shapes according to the utility model, change made by principle, it should all cover within the protection scope of the present utility model.
