Description
Technical field
The invention belongs to flight-line maintenance field more particularly to a kind of motor maintenance technologies.
Background technique
Electric vehicle due to the economic convenient vehicles for having become ordinary populace first choice, and motor be electric vehicle four greatly
One of part can be regarded as the soul of electric vehicle, and only electric vehicle does not provide power, and is related to the performance and entirety of vehicle
Experience of riding.In order to guarantee that motor works normally, it is necessary to carry out care and maintenance.In addition to by operating instruction normal use, fortune
Notice that normal monitoring and maintenance are outer during row, should also be inspected periodically, carry out maintenance of motor maintenance work.It in this way can be with
Some defect are eliminated in time, prevent failure, guarantee that motor is safely and reliably run.
In motor servicing operations, wherein the maintenance to bearing is particularly important, bearing in use for some time should be clear
It washes, replaces 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 type, half every work 3-6 months, it should which cleaning is primary, rechanges lubricating grease.When oil temperature is higher, Huo Zhehuan
The motor that border condition is poor, dust is more will be cleaned often, be changed oil.It is bad for the lubricant effect of bearing in the prior art, cause
Bearing lubrication is uneven.
Summary of the invention
The purpose of the present invention is to provide a kind of electrical machmary maintenance methods, non-uniform to solve bearing lubrication in the prior art
Technical problem.
In order to achieve the above object, base case of the invention are as follows: motor maintenance technology the following steps are included:
Step 1: disassembly: the bearing removal of upper oil lubrication will be needed again to get off in motor；
Step 2: cleaning: the bearing in step 1 being put into cleaning device and is cleaned；
Step 3: drying: the bearing after cleaning being put on dryer and is dried, and preparation oils again；
Step 4: preparing material: preparing lubricating oil, drilling machine and lubricating arrangement, wherein lubricating arrangement is equipped with support
Portion, oiling portion and rotating part；
Step 5: a location hole drilling: is drilled out on one of rolling element of bearing with the drilling machine in step 4；
Step 6: lubrication: oiling to the bearing in step 3 using the oiling portion in step 4, rotating part band dynamic bearing
Rotation, realizes the lubrication of entire bearing, and the time that oils is 1~2min, rotary rpm 5r/Min；
Step 7: installation: the bearing after lubricating in step 5 being reinstalled on motor.
The beneficial effects of the present invention are:
1, 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
Large stretch of greasy dirt and other attachments removes, guarantee bearing surface clean no-sundries, facilitate subsequent lubrication.
2, in step 5 and step 6, after drilling machine drills out location hole on rolling element, bearing is carried out convenient for oiling portion
Oil lubrication, rotating part can be such that bearing rotates during oiling, bearing rotation ensure that the entire outer ring inner wall of bearing all by
Lubricating oil has been coated, the uniformity of bearing lubrication is improved, bearing a part is avoided to oil excessively, and another part is not upper
The problem of oil.
Further, step 2 middle (center) bearing passed through in cleaning device immersion, just cleaning and seminal plasma wash three processes.It impregnates
Purpose be reduce greasy dirt, attachment adhesive force, make cleaning be more easier, being cleaned twice again after immersion can be effective
Guarantee the cleaning effect of bearing, it is especially more preferable to the bearing cleaning effect of work in the presence of a harsh environment.
Further, the time impregnated in claim 2 is 5~8min.Cleaning agent is made with the room temperature kerosene in existing method
It compares, the greasy dirt adhered on bearing and impurity is made to be easy to be cleaned, improve cleaning effect and efficiency.
Further, the penetration rate of drilling machine is 30~40 in step 5.
Since the rolling element that the object of drilling is bearing causes drilling quality not high if penetration rate is too small, if drilling speed
Degree is too big, also can be too big to the impact force of bearing, be easily damaged bearing.
Further, the temperature of lubricating oil is 30~40 DEG C in step 6.
The temperature of lubricating oil, which is 30~40 DEG C, can further increase lubricant effect.
