The utility model discloses simple structure, reasonable in design, it is easy and simple to handle, fixedly connected with rubber insulation spare between ring rolling spare and large disc for can not constitute the electric pathway between motor shaft, bearing, motor end cover, the motor frame, avoid high -frequency voltage to discharge through the bearing, thereby can produce the galvanic corrosion damage to the bearing, result in making the rolling element of bearing and interior outer lane contact surface to produce unevenness, lead to the fact the bearing failure that makes the motor, guarantee the normal work of motor.
Description
Technical field
This utility model is related to wind turbine component technical field, especially a kind of Wind turbines electromotor steel end
Lid.
Background technology
Wind-driven generator is that wind energy is converted to mechanical work, and mechanical work rotor driven rotates, the electricity of final output alternating current
Power equipment.In a broad sense, wind energy is also solar energy, so alternatively wind-driven generator, be a kind of with the sun as thermal source, with big
Gas is the heat energy utilization electromotor of working media.Wind turbines electromotor steel end cap is particularly important portion in wind-driven generator
Part, traditional Wind turbines electromotor steel end cap is casting structure, complex structure, and manufacturing process is loaded down with trivial details, production cost and system
Make costly.Wind turbines electromotor is connected with converter, can there is the voltage arteries and veins of high switching frequency in electric energy transmittance process
Punching, the distribution capacity that this high-voltage pulse can be existed by each position of motor, the voltage of high frequency characteristics is produced on motor transmission shaft,
And in motor work process, if the bearing insulation shielding failure of motor, will be in motor transmission shaft, bearing, electric motor end cap, electricity
Constituting electric pathway between machine support, then high frequency voltage will be discharged by bearing, thus galvanic corrosion can be produced to bearing damaging, leading to
Make rolling element and the generation of Internal and external cycle contact surface of bearing uneven, cause to make the bearing damage of motor, affect the normal of motor
Work.
Utility model content
The technical problems to be solved in the utility model is: overcomes the deficiency in prior art, provides a kind of structure simple, absolutely
The good Wind turbines electromotor steel end cap of edge effect.
This utility model solves its technical problem and be the technical scheme is that a kind of Wind turbines electromotor steel end
Lid, including ring forging, ring forging center offers motor axis hole, is provided with big disk outside ring forging, ring forging and big disk it
Between be fixedly connected with rubber insulators；Described ring forging and big disk be provided with multiple by Wind turbines electromotor steel end cap
The installing hole being fixedly connected with other parts, big disk is provided with the locating piece of multiple raised settings；Described ring forging outer wall
It is provided with the installation portion that ring-type is connected with rubber insulators.
Further, the section of described rubber insulators be t type, rubber insulators one end pass through the first insulated bolt with
Installation portion is fastenedly connected, and the rubber insulators other end is fastenedly connected by the second insulated bolt and big disk.
Further, described installation portion thickness and big disk consistency of thickness.
The beneficial effects of the utility model are: this utility model structure is simple, reasonable in design, easy and simple to handle, in ring forging
It is fixedly connected with rubber insulators and big disk between so that between motor transmission shaft, bearing, electric motor end cap, electric machine stand not
Electric pathway being constituted, it is to avoid high frequency voltage will be discharged by bearing, thus galvanic corrosion can be produced to bearing damaging, leading to make bearing
Rolling element and Internal and external cycle contact surface produce uneven, cause to make the bearing damage of motor it is ensured that the normal work of motor.
Brief description
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 a-a to sectional view.
In figure 1. ring forging, 2. rubber insulators, 3. big disk, 4. motor axis hole, 5. the first insulated bolt, 6. second is exhausted
Edge bolt, 7. locating piece, 8. installing hole, 11. installation portions.
Specific embodiment
Presently in connection with accompanying drawing, this utility model is further described.These accompanying drawings are the schematic diagram of simplification only to show
Meaning mode illustrates basic structure of the present utility model, and therefore it only shows the composition relevant with this utility model.
A kind of Wind turbines electromotor steel end cap as shown in Figure 1-2, including ring forging 1, ring forging 1 center offers
Motor axis hole 4, is provided with big disk 3, is fixedly connected with rubber insulators 2 between ring forging 1 and big disk 3 outside ring forging 1；
Ring forging 1 is provided with multiple installations being fixedly connected Wind turbines electromotor steel end cap with other parts with big disk 3
Hole 8, big disk 3 is provided with the locating piece 7 of multiple raised settings；Ring forging 1 outer wall is provided with what ring-type was connected with rubber insulators 2
Installation portion 11.
The section of rubber insulators 2 is t type, and rubber insulators 2 one end is fastened with installation portion 11 by the first insulated bolt 5
Connect, rubber insulators 2 other end is fastenedly connected with big disk 3 by the second insulated bolt 6；Installation portion 11 thickness and big disk
3 consistency of thickness.
This Wind turbines electromotor steel end cap structure is simple, reasonable in design, easy and simple to handle, in ring forging 1 and great circle
It is fixedly connected with rubber insulators 2 so that being unable to structure between motor transmission shaft, bearing, electric motor end cap, electric machine stand between disk 3
Becoming electric pathway, it is to avoid high frequency voltage will be discharged by bearing, thus galvanic corrosion can be produced to bearing damaging, leading to the rolling making bearing
Kinetoplast and Internal and external cycle contact surface produce uneven, cause to make the bearing damage of motor it is ensured that the normal work of motor.
Above-mentioned embodiment is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with this skill
