Description
Technical field
This utility model relates to cylinder or oil cylinder field, specifically, is related specifically to a kind of cylinder with novel bearing or oil cylinder。
Background technology
Cylinder or oil cylinder are the conventional actuators in industrial products, are used for realizing displacement transmission and thrust control。Traditional cylinder or oil cylinder generally adopt copper sheathing or bearing as guide post, can cause friction in the process of slide-and-guide。The existence of a large amount of frictions, causes that cylinder or cylinder thrust can not realize accurate, accurate and constant control。Market use bearing as the cylinder led or oil cylinder, in the process of work, the steel ball of energy load capacity simultaneously is fewer, distribution of force is uneven, make cylinder or cylinder force uneven while increasing single steel ball bearing pressure, easily wear and tear with steel ball contact site, greatly reduce the reliability of cylinder or oil cylinder and the service life of cylinder or oil cylinder。
Utility model content
The purpose of this utility model is in that for deficiency of the prior art, it is provided that a kind of cylinder with novel bearing or oil cylinder, to solve the problems referred to above。
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of cylinder with novel bearing or oil cylinder, including cylinder body, piston, piston rod and guide post, parallel on cylinder body offer cylinder-bore and pilot hole, piston is connected with piston rod and is located in cylinder-bore, guide post is located in pilot hole, also include the bearing being located in pilot hole, described bearing includes ball, retainer and the outer ring being sheathed on retainer, outer ring and cylinder body interference fit, retainer is column structure, retainer boring forms directed cavity, guide post is arranged in directed cavity, retainer uniformly offers the hole of bead, described ball is respectively arranged in the hole of bead of correspondence, the two ends of ball are respectively exposed to outer wall and the inwall of retainer, and it is tangent with the outer wall of the inwall of outer ring and guide post respectively。
Further, described ball and the hole of bead adapt, and the diameter of ball is more than the orifice diameter at two ends, the hole of bead。
Further, the axial length of described retainer is less than the length of outer ring。
Further, the quantity of described guide post is at least one, corresponding, the quantity of described bearing is at least one, and bearing and guide post one_to_one corresponding are arranged。
Compared with prior art, the beneficial effects of the utility model are as follows:
This utility model compact conformation, guiding accuracy is high, piston rod and cylinder surface uniform force can be made, wear and tear little, smooth operation, wearability and resist heavy duty ability improve, substantially increase the fatigue strength of cylinder or oil cylinder, make cylinder body can bear bigger radial and axial pressure, add the reliability of use, extend service life。
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of cylinder with novel bearing described in the utility model or oil cylinder。
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further。
A kind of cylinder with novel bearing or oil cylinder, including cylinder body 1, piston 2, piston rod 3, guide post 64 and bearing。Parallel cylinder-bore and the pilot hole of offering on cylinder body 1, piston 2 is connected with piston rod 3 and is located in cylinder-bore。The bottom of cylinder-bore is provided with cushion chamber 11。Piston 2 is provided with wear ring 9。Piston rod 3 is sealed by sealing ring 10。Cylinder-bore be respectively arranged at two ends with upper end cover 4 and bottom end cover 5。Guide post 64 and bearing are located in pilot hole。Bearing is provided with in pilot hole, including ball 62, retainer 61 and the outer ring 63 that is sheathed on retainer 61。Outer ring 63 and cylinder body 1 interference fit。The axial length of retainer 61, less than the length of outer ring 63, the inwall at two ends, outer ring 63 offers groove, is provided with spacing back-up ring (not drawing in figure) in groove。Retainer 61 is column structure, and retainer 61 boring forms directed cavity, and guide post 64 is arranged in directed cavity。Uniformly offering the hole of bead on retainer 61, ball 62 is respectively arranged in the hole of bead of correspondence。Ball 62 and the hole of bead adapt, and the diameter of ball 62 is more than the orifice diameter at two ends, the hole of bead。The two ends of ball 62 are respectively exposed to outer wall and the inwall of retainer 61, and tangent with the outer wall of the inwall of outer ring 63 and guide post 64 respectively。
The quantity of guide post 64 is at least one, corresponding, the quantity of bearing is at least one, and bearing and guide post 64 one_to_one corresponding are arranged。The top of cylinder body 1 is provided with briquetting 7, and briquetting 7 is connected with the top of piston rod 3, guide post 64 respectively by installing bolt 8。
This utility model is in the process used, and briquetting 7 drives guide post 64 and piston rod 3 reciprocating。In the process of motion, the two ends of ball 62 contact with the outer wall of the inwall of outer ring 63 and guide post 64 respectively and make to roll slip, and ball 62 distribution of force is uniform；Retainer 61 slides together along with guide post 64, and the twice that the stroke of guide post 64 is retainer 61 stroke, and guiding accuracy is high。
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described。Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model。This utility model claims scope and is defined by appending claims and equivalent thereof。
