Description
Technical field
The utility model relates to a kind of rotary shafts and axle sleeve insulated transmission structure, belong to mechanical transmission structure field.
Background technique
Transmission shaft and axle sleeve with the use of being widely used in mechanical equipment instantly, such as fan motor transmission shaft with
Cooperation between flabellum, the cooperation etc. between the motor transmission shaft and rotor of vacuum sliding vane rotary pump.
But in axle sleeve, there are under high voltage condition, it is desirable that meets specific insulation between initiative drive shaft and passive axle sleeve and wants
It asks, otherwise will give the connected motor of initiative drive shaft and bring fatal damage；And traditional transmission shaft and axle sleeve are metal,
Resistance between transmission shaft and axle sleeve is generally less than 1 Ω, is unable to satisfy electrical isolation and requires.
Summary of the invention
In order to overcome the deficiencies in the prior art described above, the purpose of this utility model is to provide a kind of rotary shaft and axle sleeves
Insulated transmission structure, to solve the problems, such as being dielectrically separated between rotary shaft and axle sleeve in the prior art, the drive mechanism can
The resistance between initiative drive shaft and passive axle sleeve is significantly increased, and does not influence machinery driving efficiency.
To realize the purpose of this utility model, following technical scheme is provided.
A kind of rotary shaft and axle sleeve insulated transmission structure, the drive mechanism include initiative drive shaft, passive axle sleeve and absolutely
Edge ceramic block.
Initiative drive shaft is located in passive axle sleeve, and rack gear, the inner circle of passive axle sleeve are machined in the outer circle of initiative drive shaft
On be machined with tooth socket, rack gear and tooth socket quantity are equal, and rack gear is more smaller than tooth socket, can be inserted into tooth socket and in two sides mating surface and
There are gaps between end, wherein gap of the gap of two sides mating surface to be coupled insulating ceramics block, between end face portion
Those skilled in the art can carry out adaptability design according to the size of required resistance.
The quantity of rack gear and tooth socket is equal, and is both greater than equal to 2.
The material and shape and size of the insulating ceramics block can be set according to the gap of rack gear and tooth socket two sides mating surface
Meter；It can be rectangular patch, thickness is equal with the gap of rack gear and tooth socket two sides mating surface.
Beneficial effect
The utility model provides a kind of rotary shaft and axle sleeve insulated transmission structure, can be according to not compared with traditional technology
Corresponding insulating ceramics type is selected with operating condition, solves the Insulation Problems between initiative drive shaft and passive axle sleeve.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of rotary shaft and axle sleeve insulated transmission structure in embodiment.
1-initiative drive shaft, 2-passive axle sleeves, 3-insulating ceramics blocks
Specific embodiment
It is described in further details below with reference to method of the embodiment to the utility model.
Embodiment 1
As shown in Figure 1, a kind of rotary shaft and axle sleeve insulated transmission structure, the drive mechanism include initiative drive shaft 1, quilt
Moving axis set 2 and insulating ceramics block 3.
Initiative drive shaft 1 is located in passive axle sleeve 2, and rack gear is machined in the outer circle of initiative drive shaft 1, passive axle sleeve 2
Be machined with tooth socket in inner circle, rack gear and tooth socket quantity it is equal be 8, and rack gear is more smaller than tooth socket, can be inserted into tooth socket and
There are gaps between two sides mating surface and end, wherein two sides mating surface is parallel to each other, between gap be 2mm, to cooperate peace
The rectangular patch alumina insulation ceramic block 3 of 2mm thickness is filled, the clearance distance between end face portion is remained above 3mm.
Experiment shows rotary shaft provided by the utility model and axle sleeve insulated transmission structure, can effectively increase and actively pass
Resistance between moving axis 1 and passive axle sleeve 2, under conditions of 1000V potential difference, insulation resistance is greater than 50G Ω.
Certainly, above only with concrete application range of the invention, protection scope of the present invention is not limited in any way.It removes
Outside above-mentioned embodiment, the present invention can also have other embodiments.All technologies formed using same replacement or equivalent transformation
Scheme should be covered within the scope of the utility model.
