Abstract
The invention relates to the technical field of linear guide rail accessories, in particular to a linear ball guide sleeve which is widely applied to sliding parts of a lathe, a grinder and other mechanical devices. The linear ball guide sleeve comprises a rotating shaft and a bearing sleeve, wherein the outside of the rotating shaft is sleeved with the bearing sleeve. The bearing sleeve comprises a holding frame and a bearing sleeve shell. Balls are arranged between the holding frame and the bearing sleeve shell. Stop rings are arranged at the two ends of the bearing sleeve. A pin hole is formed in the outside of the bearing sleeve shell. A pin is inserted into the pin hole to connect the holding frame with the bearing sleeve shell. The rotating shaft is provided with a plurality of circular arc-shaped rolling channels. According to the linear ball guide sleeve, the design is reasonable; the rotating shaft is provided with the multiple circular arc-shaped rolling channels so that the rated load can be improved; an oil injection hole is formed so that the lubrication performance of the linear ball guide sleeve can be improved; the abrasion resistance of the linear ball guide sleeve is improved and the service life is prolonged; the stop rings are arranged at the two ends of the bearing sleeve, and thus the linear ball guide sleeve has the advantage of dust prevention.
Description
Technical field
The present invention relates to linear rail attachment technique field, especially a kind of straight-line ball guide pin bushing being widely used in the machinery such as lathe, grinding machine sliding position.
Background technique
Linear rail is widely used in various industry equipment and precision type instrument, and as wherein vitals, precision and the wear-resisting property of straight-line ball guide pin bushing are all greatly improved.But traditional straight-line ball guide sleeve structure is complicated, install and keep in repair loaded down with trivial details, precision and stationary performance are all not high, and wear-resisting property is poor, greasy property is also bad, need often maintenance or change, after service time is long, wearing and tearing very large, and can generate heat, working life can shorten, and reduces manufacturing efficiency, improves cost of production.Therefore, a kind of new technological scheme is needed to solve the problem.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, the straight-line ball guide pin bushing of long service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of straight-line ball guide pin bushing, comprise rotating shaft and be set in the bearing housing outside rotating shaft, bearing housing comprises retainer and bearing housing shell, ball is provided with between retainer and bearing housing shell, described bearing housing two ends are provided with stop ring, be provided with pin-and-hole outside bearing housing shell, insert pin in pin-and-hole and retainer and bearing housing shell are coupled together; Described rotating shaft offers the rolling raceway groove of many circular arcs, do not need the mechanism preventing bearing housing from rotating, its load rating increases substantially.The compactness of pilot construction can be realized, cost degradation and long lifetime.
Further, described bearing housing shell is provided with the oil hole injecting lubricant oil.
Further, described rotating shaft offers four rolling raceway grooves.
Further, described retainer is resin cage.
Further, described retainer is stainless steel holder.
The invention has the beneficial effects as follows: the present invention is reasonable in design, rolling raceway groove rotating shaft offering many circular arcs can improve load rating, be provided with the greasy property that the oil hole that can inject lubricant oil can improve straight-line ball guide pin bushing, improve the wear-resisting property of straight-line ball guide pin bushing, increase the service life, bearing housing two ends are provided with stop ring, have dust-proof advantage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. rotating shafts in figure, 2. bearing housing shell, 3. retainer, 4. ball, 5. stop ring, 6. pin-and-hole, 7. oil hole, 8. rolling raceway groove.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of straight-line ball guide pin bushing as shown in Figure 1, the bearing housing comprising rotating shaft 1 and be set in outside rotating shaft 1, bearing housing comprises retainer 3 and bearing housing shell 2, ball 4 is provided with between retainer 3 and bearing housing shell 2, bearing housing two ends are provided with stop ring 5, be provided with pin-and-hole 6 outside bearing housing shell 2, insert pin in pin-and-hole 6 and retainer 3 and bearing housing shell 2 are coupled together; Rotating shaft 1 offers the rolling raceway groove 8 of four circular arcs.
Bearing housing shell 2 is provided with the oil hole 7 injecting lubricant oil; Retainer 3 is resin cage.
Rotating shaft 1 offers the rolling raceway groove 8 of four circular arcs, ball 4 rolls in rolling raceway groove 8, does not need the mechanism preventing bearing housing from rotating, and the load rating of straight-line ball guide pin bushing increases substantially.The compactness of pilot construction can be realized, cost degradation and long lifetime.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
