Abstract
The present invention relates to bearing technology manufacture field, specifically a kind of self-aligning thrust roller bearing abrasive grinding wheel.The grinding wheel is arc-shaped, grinding wheel minimum wall thickness (MINI W.) H >=50mm, grinding wheel minimum diameter D >=350mm, angle of the angle " α " equal to self-aligning thrust roller bearing blowout patche raceway two o'clock line and centre of gyration line；Size " R " is equal to self-aligning thrust roller bearing blowout patche raceway radius.Grinding wheel of the present invention is suitable for the ball race grinding of medium-and-large-sized self-aligning thrust roller bearing, improves processing efficiency, reduces the probability for generating waste product.Such product is widely used in the various fields such as extruding machine, preheater.
Description
Technical field
The present invention relates to bearing technology manufacture field, specifically a kind of novel self-aligning thrust roller bearing abrasive grinding wheel.
Background technique
Currently, when processing medium-and-large-sized self-aligning thrust roller bearing, ball race grinding is last process, and require highest,
Process the part being most difficult to.The most common problem is " side of raising " in process, that is, the grinding wheel being ground is in processing raceway root
When, small rib can be touched, small rib is ground off into a part, generates waste product.In order to solve the generation of such case, grinding race
When be not worked into root, reserve a part return turner, remaining raceway part is subjected to hard vehicle with lathe tool, not only processing imitate
Rate is low, and processing effect is bad, therefore, studies the completely new grinding wheel of one kind to be processed into the task of top priority.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of novel self-aligning thrust roller bearing abrasive grinding wheel.
For achieving the above object, the invention adopts the following technical scheme:
A kind of novel self-aligning thrust roller bearing abrasive grinding wheel, the grinding wheel are arc-shaped, grinding wheel minimum wall thickness (MINI W.) H >=50mm, sand
Minimum diameter D >=350mm is taken turns, angle " α " is equal to self-aligning thrust roller bearing blowout patche raceway two o'clock line and centre of gyration line
Angle；Size " R " is equal to self-aligning thrust roller bearing blowout patche raceway radius.
Compared with prior art, the invention has the benefit that grinding wheel of the present invention is suitable for medium-and-large-sized thrust force aligning roller
The ball race grinding of bearing improves processing efficiency, reduces the probability for generating waste product.Such product is widely used in extruding machine, pre-
Hot device etc. various fields.
Detailed description of the invention

Fig. 2 tradition grinding wheel structure schematic diagram；
Fig. 3 tradition wheel grinding schematic diagram；
In figure, 1. traditional grinding wheels, 2. " sides of raising ", 3. blowout patches；
Fig. 4 wheel grinding schematic diagram of the present invention；
In figure, 4. grinding wheels of the present invention, 5. small ribs, 3. blowout patches.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings.
A kind of novel self-aligning thrust roller bearing abrasive grinding wheel, which is characterized in that the grinding wheel is arc-shaped, grinding wheel minimum
Wall thickness H >=50mm, grinding wheel minimum diameter D >=350mm, by self-aligning thrust roller bearing blowout patche raceway two o'clock line and the centre of gyration
The angle of line rounds up numerical value, as angle " α "；Size " R " is equal to self-aligning thrust roller bearing blowout patche raceway radius.
Attached drawing 3 is the grinding method of traditional grinding wheel, from the figure, it can be seen that allow grinding wheel to be worked into raceway and small gear
Small rib is ground off into a part, generates waste product then grinding wheel has just been contacted with small rib in side root.
Attached drawing 4 is wheel grinding mode of the present invention, it can be seen from the figure that effectively avoiding small gear using grinding wheel
Primary grinding is realized on side 5.But it may be noted that the angle of grinding wheel central axis and bearing central axis no more than 60 ゜, otherwise
Grinding force will be will affect.
