Description

A kind of bearing with spherical outside surface
Technical field
The utility model relates to mechanical engineering Element Technology field, is specifically related to a kind of bearing.
Background technique
Lubricated fatigue life to rolling bearing and friction, wearing and tearing, temperature rise, vibration etc. have material impact, if bearing does not lubricate through normal, the performance of bearing and life-span will reduce greatly.Show according to data analysis, the bearing damage of 40% left and right is all relevant with insufficient lubrication.Therefore, to bearing as effectively lubricating, be the effective measures that reduce pivot friction and wearing and tearing.And, effectively lubricated can also be to the heat radiation of bearing, antirust, sealing, relax the useful effect of playing of impacting.Make bearing with spherical outside surface that good working environment be arranged, give full play to its service behaviour, increase the service life, must inject moderate lubrication fat in the lubricating cavity of bearing after bearing with spherical outside surface uses a period of time.and existing bearing with spherical outside surface, particularly GB UCP serial band base spherical outside surface bearing is all to adopt " indirect mode " to carry out oil injecting lubricating, namely pass through the oil nozzle on bearing support top, the oil guide slot on bearing support inwall and surface, outer ring and oil guiding hole inject lubricating grease or lubricant oil in lubricating cavity, owing to having fit up gap between bearing with spherical outside surface body and bearing support, particularly in the bearing with spherical outside surface working procedure, fit up gap can be strengthened because of the deformation that bearing produces, dust and foreign matters from being blocked oil guiding hole and can't be the bearing oil injecting lubricating, moreover, sometimes also can make oil guide slot and oil guiding hole produce dislocation when the bearing with spherical outside surface aligning and can't oiling, cause the reduction greatly in bearing with spherical outside surface service behaviour and life-span.
The model utility content
In view of the deficiency of prior art, the utility model provides a kind of bearing with spherical outside surface, and this bearing has overcome the defect of existing bearing oiling, has greatly improved performance and the life-span of bearing.
The scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of bearing with spherical outside surface, comprise first pump nozzle that is positioned at bearing support top, one and bearing support is the bearing outer ring, a bearing inner race of sphere-contact, a plurality of steel ball, that is uniformly distributed in the middle of bearing inner race and bearing outer ring is placed in the retainer on steel ball, 2 seal ring and 2 stop pin of being located on the spherical outer wall of bearing outer ring that are placed between bearing inner race, bearing outer ring, it is characterized in that
Upper one second pump nozzle that also is provided with of the axial outward direction of described bearing inner race, the inwall of the bearing inner race corresponding with this second pump nozzle position is provided with one along the inside oil guide slot of bearing inner race axial direction, the inside end of oil guide slot is positioned at the lubricating cavity bottom that bearing outer ring, bearing inner race and seal ring surround, and is provided with the oil guiding hole of a connection lubricating cavity and oil guide slot.
Under guaranteeing that bearing with spherical outside surface in working order, be placed in the rotating shaft of bearing inner race inside and bearing inner race does not produce relative rotation and rotating shaft does not produce vibration when running up, or when oiling, rotating shaft and oil guide slot can close to coordinate and form the oiling passage of sealing more, and described bearing inner race circle wall also is provided with a rotating shaft securing means on the position corresponding with the oiling through hole.
For guaranteeing bearing with spherical outside surface manufacture cost and versatility, described rotating shaft securing means can adopt interior hexagonal Cock screw.
The beneficial effect of bearing with spherical outside surface provided by the utility model is:
due to the utility model when not abandoning original pump nozzle and providing lubricating function between for bearing outer ring and bearing support, adopted the mode of " directly " oiling, utilize the closed oiling passage that forms of rotating shaft and oil guide slot, make the oiling through hole that is positioned on bearing inner race pass through oil guide slot, oil guiding hole and bearing outer ring, the lubricating cavity that bearing inner race and seal ring surround directly is communicated with, lubricant grease can be injected in lubricating cavity smoothly, even bearing with spherical outside surface is after any direction and angle aligning, also can guarantee smooth oiling, and owing to also being provided with a rotating shaft securing means on the bearing inner race circle wall position corresponding with the oiling through hole, stability when this device not only improves the bearing rotation, also greatly reduced simultaneously the fit up gap of oiling path, reduced the oiling path by the possibility of foreign body obstruction, thereby improved the performance of bearing with spherical outside surface and extended its working life.
Description of drawings
Fig. 1~Fig. 5 is respectively front elevation, A-A sectional view, rear view, bearing inner race oiling path partial enlarged drawing and the top view of a specific embodiment of a kind of bearing with spherical outside surface described in the utility model.
Embodiment
This example is a kind of bearing with spherical outside surface with the vertical shaft bearing provided by the utility model.As shown in Fig. 1~5, this bearing with spherical outside surface comprise first pump nozzle 13 that is positioned at the bearing support crown center, one and vertical shaft bearing 6 be sphere-contact bearing outer ring 5, a bearing inner race 3, a plurality ofly be uniformly distributed in steel ball 4 in the middle of bearing inner race 3, bearing outer ring 5, be placed in retainer 7 on steel ball, be placed between bearing inner race, bearing outer ring, 2 seal rings 8 and 2 stop pin 11 of being located on the spherical outer wall of bearing outer ring of being used for the closed lubrication chamber, this bearing with spherical outside surface also comprises one second pump nozzle 1 in addition, wherein
Described the second pump nozzle 1 is located on the position of axial outward direction of bearing inner race 3, the inwall of the bearing inner race 3 corresponding with this second pump nozzle 1 position is provided with one along the inside oil guide slot 2 of bearing inner race axial direction, the inside end of oil guide slot 2 is positioned at the lubricating cavity bottom that bearing outer ring 5, bearing inner race 3 and seal ring 8 surround, and is provided with an oil guiding hole that runs through bearing inner race 3.
