Embodiment
Below in conjunction with Figure of description and specific embodiment technological scheme of the present invention done and further elaborate.
Apparatus embodiments one:
As shown in Figure 1, the present embodiment provides a kind of bearing, and described bearing comprises:
Axle center 101;
Bearing support 102, for installing described axle center 101;
Groove 103, on the opposing side between described axle center 101 and described bearing support 102, for storing lubricant oil and/or disperseing the oil pressure of described lubricant oil.
Usually emptied in the middle of bearing support 102, be provided with the space of installing described axle center 101, described axis 101 can rotate relative to described bearing support 102 usually.A kind of important spare part in bearing mechanical equipment.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two.Wherein rolling bearing standardization, seriation, but its radial dimension, vibration & noise is comparatively large compared with sliding bearing, and price is also higher.
Usually bearing support 102 is smooth with the surface of contact in axle center 101 in the prior art, to reduce frictional force as much as possible.But in the bearing described in the present embodiment, bearing support 102 and axle center 101 at least one of them, for with another component opposing faces on be provided with groove 103, this groove 103 may be used for storing lubricant oil superfluous between bearing support 102 and axle center 101, thus the oil pressure between dispersion bearing support 102 and axle center 101, thus avoid the leakage phenomenon that causes when lubricant oil is too much between bearing support 102 and axle center 101.Simultaneously, by the design of groove 103, more lubricant oil can be stored between bearing support 102 and axle center 101, avoid the consumption that lubricant oil is too early, what interpolation lubricant oil caused frequently is loaded down with trivial details, can reduce because forgetting the stuck phenomenon of adding lubricant oil and causing simultaneously.
As can be seen from Figure 1, between bearing support 102 and axle center 101, be provided with gap, between this gap, can be used for the filling of lubricant oil.
