Description
Technical field
The present invention relates to a kind of greasing mould of two-row ball bearing, particularly special-shaped two-row ball bearing greasing mould.
Background technique
In the technique of different special-shaped two-row ball bearing assembling more difficult point is arranged, greasing is exactly one of them.
What of the oil quantity that bearing is annotated are important quality index of bearing, and oil quantity is many fat phenomenon can to occur leaking, and when occurring leaking fat, grease drips on the belt pulley, causes belt pulley to skid; Oil quantity has lacked the life-span that can affect bearing.
Greasing to two-row ball bearing, traditional technique is to annotate a grease to turn over afterwards and annotate another side again, but the method that detects greasing amount is to take the method for weighing, greasing amount is poor before and after the bearing weight after the greasing, if operator's misoperation and only the one side annotating grease twice, can't detect whether two-sided all greasings.Annotate grease twice if there is a face, one side is leaked fat because grease, and another side is because making the bearing earlier period damage without grease.
Also there is larger difference location when the zanjon of abnormity tension wheel shaft bearing and conventional construction and the ball bearing greasing of biserial, traditional greasing mould is located with internal diameter, the inside and outside circle of bearing is highly basic identical, but special-shaped two-row ball bearing is different, what have does not have an endoporus, some endoporus are irregular, can not finely locate.
Summary of the invention
Technical problem to be solved by this invention provides a kind of special-shaped two-row ball bearing greasing mould, can be to special-shaped two-row ball bearing be carried out efficient greasing and mistake proofing, for this reason, the present invention by the following technical solutions:
Comprise top mold frame and lower mold holder, described top mold frame, lower mold holder are equipped with respectively upper fat injecting mechanism, lower fat injecting mechanism, described upper fat injecting mechanism comprises columned upper greasing headgear, upper greasing head core, described upper greasing head core is fixed in the greasing headgear, described lower fat injecting mechanism comprises columned lower greasing headgear, lower greasing head core, described lower greasing head core is fixed in the lower greasing headgear, the top mold frame at described upper greasing headgear and place is connected, and the lower mold holder at described lower greasing headgear and place is connected;
Described upper greasing head core and lower greasing head core all have the pocket hole that suitable bearing inner race inserts at the end in the face of bearing, the other end has the middle grease main passage that extends internally from greasing head core end, form grease wriggling path between the external cylindrical surface of the inner cylindrical surface of described upper greasing headgear and upper greasing head core, also form grease wriggling path between the external cylindrical surface of the inner cylindrical surface of described lower greasing headgear and lower greasing head core, described upper greasing head core and lower greasing head core all are provided with the grease subchannel in UNICOM grease main passage and grease wriggling path, and described pocket hole and grease main passage and grease subchannel are spaced;
Described grease wriggling path has the greasing mouth at the end top near bearing, and described greasing mouth can stretch into when work and carry out greasing between bearing inner race and the outer ring.
On the basis of adopting above technological scheme, the present invention can also adopt following further technological scheme:
Described greasing mouth dwindles gradually at the top.The external cylindrical surface top of described upper greasing head core gradually upwards the inner cylindrical surface of greasing headgear draw close, the external cylindrical surface top of described lower greasing head core gradually downwards the inner cylindrical surface of greasing headgear draw close so that the greasing mouth dwindles gradually at the top.
Described greasing head cover utilizes bolt or screw and mould to fix.
Described upper greasing head core has the annular boss that is fixed with upper greasing headgear at the end near top mold frame, and described lower greasing head core has the annular boss that is fixed with lower greasing headgear at the end near lower mold holder.
The pocket hole height of described lower greasing head core can adapt to the inner ring of special-shaped two-row ball bearing and the different situation of height of outer ring greater than the different height of pocket hole height of upper greasing head core.
The present invention can be to the simultaneously greasing of two-row ball bearing two sides.Greasing head is realized the location to bearing under main the employing.When to the bearing grease injection of single-row ball, fat injecting mechanism gets final product in the cancellation.
Owing to having adopted technological scheme of the present invention, adopted the top mold frame and the lower mold holder that are equipped with fat injecting mechanism to be simultaneously special-shaped two-row ball bearing greasing, part is few, compact structure, processing and greasing good positioning effect, versatility is stronger, single-row, the bearing of double-row-ball all can carry out greasing, prevent and stopped in the tratitional technology owing to only too much or only occuring in the situation of one side greasing in the one side greasing of special-shaped two-row ball bearing that operate miss causes, has stronger error-disable function, guarantee quality and the working life of ball bearing, and then guaranteed the Security in the bearing using process.
