Description
Technical field
The invention belongs to flight-line maintenance field, more particularly to a kind of motor maintenance technology.
Background technology
Electric car is due to the economic convenient vehicles for having become ordinary populace first choice, and motor is the four big of electric car
One of part, can be regarded as the soul of electric car, and only electric car does not provide power, and is related to the performance and entirety of vehicle
Experience of riding.In order to ensure that motor works normally, it is necessary to carry out care and maintenance.Except by operational procedure normal use, fortune
Outside normal monitoring is paid attention to during row and is safeguarded, it should also be inspected periodically, carry out maintenance of motor maintenance work.So can be with
Some defect are eliminated in time, prevent failure, ensure that motor safety is reliably run.
In motor servicing operations, wherein it is particularly important that maintenance to bearing, bearing in use for some time should be clear
Wash, replace lubricating grease or lubricating oil.The time cleaned and changed oil, should be with the working condition of motor, working environment, clean-up performance,
Depending on lubricant species, half often works 3-6 months, it should which cleaning once, rechanges lubricating grease.When oil temperature is higher, Huo Zhehuan
The motor that border condition is poor, dust is more will often clean, change oil.It is bad for the lubricant effect of bearing in the prior art, cause
Bearing lubrication is uneven.
The content of the invention
It is non-uniform to solve bearing lubrication in the prior art it is an object of the invention to provide a kind of electrical machmary maintenance method
Technical problem.
In order to achieve the above object, base case of the invention is：Motor maintenance technology comprises the following steps：
Step 1：Dismounting：The bearing removal that upper oil lubrication is needed again in motor is got off；
Step 2：Cleaning：Bearing in step 1 is put into cleaning device and is cleaned；
Step 3：Drying：Bearing after cleaning is put on dryer and is dried, preparation oils again；
Step 4：Prepare material：Prepare lubricating oil, drilling machine and lubricating arrangement, wherein lubricating arrangement is equipped with support
Portion, oiling portion and rotating part；
Step 5：Drilling：A location hole is drilled out on one of rolling element of bearing with the drilling machine in step 4；
Step 6：Lubrication：Oiled using the oiling portion in step 4 to the bearing in step 3, rotating part band dynamic bearing
Rotation, realizes the lubrication of whole bearing, the time that oils is 1~2min, rotary rpm 5r/Min；
Step 7：Installation：Bearing after being lubricated in step 5 is reinstalled on motor.
The beneficial effects of the present invention are：
1st, in step 1, step 2 and step 3, bearing removal is cleaned after getting off, and its object is to will be attached above bearing
The large stretch of greasy dirt and other attachments are removed, and are ensured bearing surface clean no-sundries, are facilitated follow-up lubrication.
2nd, in step 5 and step 6, after drilling machine drills out location hole on rolling element, bearing is carried out easy to oiling portion
Oil lubrication, rotating part can be such that bearing is rotated during oiling, bearing rotate ensure that the whole outer ring inner wall of bearing all by
Lubricating oil has been coated, has improved the uniformity of bearing lubrication, has avoided a bearing part from oiling excessively, and another part is not upper
The problem of oily.
Further, step 2 middle (center) bearing passed through immersion in cleaning device, just cleaning and seminal plasma wash three processes.Immersion
Purpose be reduce greasy dirt, the adhesive force of attachment, be more prone to cleaning, being cleaned twice again after immersion can be effective
Ensure the cleaning performance of bearing, it is especially more preferable to the bearing cleaning effect to work in the presence of a harsh environment.
Further, the time soaked in claim 2 is 5~8min.Cleaning agent is made with the room temperature kerosene in existing method
Compare, make the greasy dirt that adheres on bearing and impurity easily be cleaned, improve cleaning performance and efficiency.
Further, the penetration rate of drilling machine is 30~40 in step 5.
Due to the rolling element that the object of drilling is bearing, as penetration rate is too small, cause drilling quality not high, if drilling speed
Degree is too big, also can be too big to the impact force of bearing, is easily damaged bearing.
Further, the temperature of lubricating oil is 30~40 DEG C in step 6.
The temperature of lubricating oil can further improve lubricant effect for 30~40 DEG C.
