The 07087x bearing for electric vehicle motors achieves new heights
07087x bearing for electric vehicle motors achieves new heights
vehicles, which have been rapidly spreading in recent years, have received
widespread attention from society due to their low environmental impact and
their ability to cope with increasingly stringent vehicle fuel consumption
restrictions. There is an increasing demand for the development of technologies
to improve the power efficiency and reliability of automobiles.
them, automobile motors, which are directly related to the improvement of
automobile fuel consumption and power consumption, are gradually becoming
smaller and have higher output, and the demand for 07087x bearings that support
the high-speed rotation performance of the motor is also increasing. Therefore,
it has become a problem to develop a 07087x bearing that does not cause damage
or burns even under high-speed rotation.
this context, a well-known foreign bearing research and development company
responded to the needs of the times and developed a 07087x bearing with better
high-speed rotation and reliability, which eases the stress generated by the
centrifugal force acting on the cage during high-speed rotation, and optimizes
The size design of each part has achieved a DMN value of 1.85 million or more
for the 07087x bearing.
the future, it is expected that the demand for smaller and higher output BEV
motors will further accelerate, requiring not only high-speed rotation
performance but also high-speed rotation performance in high-temperature
environments. The 07087x bearing is expected to be further upgraded to cope
with future market changes.
The 07087x bearing technical
Shorten the running time of grease
successfully developed the rolling element guide cage, which has the same
durability as existing products. By improving the shape of the cage and
improving the discharge performance of excess grease, compared with the general
outer ring guide cage, the running-in time of grease lubrication can be
shortened by about 70% at the maximum.
Reduce abnormal temperature rise during oil-air lubrication
the condition of oil-air lubrication, the traditional outer ring guidance
method is difficult to solve the excessive temperature rise caused by too much
lubricating oil inside the bearing at low speed. The rolling element guide
method can solve the above problems and realize the stable operation of the
main shaft during oil-air lubrication.
Improve the reliability of the rolling element guide cage
at the problem of easy damage to cages guided by rolling elements, NSK
optimized the material and shape of the cage to improve the durability
(reliability) of the cage guided by the rolling elements.
07087x bearing development effect
technology can shorten the assembly time of grease-lubricated spindles and
improve the production efficiency of machine tool manufacturers. At the same
time, the abnormal temperature rise during oil-air lubrication is reduced, the
strength of the roller guide cage is improved, and high reliability is
07087x bearing use
machining centers for forming automotive parts and general mechanical parts,
the electric spindle with a built-in motor generates axial elongation due to
self-heating. Therefore, cylindrical roller bearings are generally used at the
back end of the spindle. The new technology developed by NSK this time is most
suitable for the back-end support bearing of the spindle.
impact of new bearings on 07087x bearing in the automotive industry
07087x bearing is mainly used to complement the host industry, including
automobiles, home appliances, medical equipment and other industries. The
development of related industries will drive the demand of the industry. China
auto market has maintained a trend of rapid growth in recent years. Considering
factors such as car ownership, per capita income, and per capita car ownership,
cars are still in the incremental market and have not been transferred to the
stock market. According to the "2015-2020 China Bearing Manufacturing
Industry Production and Sales Demand Forecast and Transformation and Upgrade
Analysis Report" released by the Foresight Industry Research Institute,
the high growth rate of the automotive industry will continue for a period of
time, and the future growth rate will not be less than 15%.
the process of miniaturization and electrification of automobiles, the
corresponding component products are constantly increasing. Therefore, the
automotive-related parts market will continue to expand in the future. The
development of automotive bearings will focus on safety, improving efficiency
and reducing harmful substances. Automobile radiator cooling fan motor, wiper
motor, exhaust gas recirculation system (EGR) valve frame and anti-lock brake
system (ABS) represented by oil pump motors and their application systems are
the main application areas of miniature bearings.
particular, the 07087x bearing for ABS was only used for high-end cars in the
1980s. After that, it was used as an important product for safety measures in
the direction of miniaturization and popularization, and its use has been
continuously expanded since the mid-1990s. The automobile spindle developed at
present is developing towards multi-function and safety. It not only uses the
07087x bearing to control the brake intermittently, but also links with the
sensor that monitors the driving situation, and transmits different braking
forces to the front, rear, left, and right wheels. Control safe driving as a
whole. The future development trend of miniature bearings. This system is an
ABS upgrade system. Different manufacturers have different 07087x bearing such
as ESC, EPS, VSC and so on.
The development of ABS system is a
typical example of the development of automobile-related products. In the
future, 07087x bearing will derive many new application products with
increasing requirements for safety and environmental protection. The imported
bearing market aims at hybrid vehicles and electric vehicles to try to create
new types of car-related products. In this development, the field of miniature
bearings will continue to expand, and its precision will continue to improve.
With the continuous development of China\'s automobile industry, there is huge room
for domestic enterprises to develop. If you are looking for 07087x bearing or
