Description
Technical field
The utility model relates to technical field of mechanical transmission, is specially a kind of material machine of taking off linear bearing that can be used for taking off on material machine.
Background technique
In technical field of mechanical equipment, linear bearing mainly comprises inner sleeve, overcoat and rolling element, rolling element made by general employing steel ball, some raceways in the cylinder-shaped bearing body be made up of inner sleeve and overcoat around axle make shuttling movement back and forth, it has low noise, low friction, highi degree of accuracy, the feature of long-life, is widely used in mechanical field.
But, due to traditional linear bearing structural design existing defects, at some medicine, food, taking off of chemical industry etc. gets rusty easily when material machine uses and affects machine operation, or there is solid accumulation and stuck phenomenon occurs in operation process, and bearing snap spring is because can not bearing the weight of Pa Liao mechanism and impact and often rupturing, linear bearing is caused to drop out, rate of fault is high, simultaneously, because the situation that signal is not in place easily appears in corrosion and wearing and tearing after the long period uses, proportion scale is caused to change, product quality is changed, cause needing often maintenance and changing.
Model utility content
The technical problem that the utility model solves is to provide one to take off material machine linear bearing, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Take off material machine linear bearing, comprise retainer, sleeve pipe and ball, wherein, described retainer is PVC retainer, ball sleeve is contained in the ball chamber of PVC retainer, and retainer is whole is installed in casing pipe, and described sleeve pipe side is provided with jump-ring slot, and opposite side is provided with circle convex annular rank, in addition, this sleeve pipe is three-layer composite structure, comprise the interior pipe of wear-resistant ceramic of outer field teflon shell and internal layer, and in teflon shell and wear-resistant ceramic, between pipe, be also provided with the PAN based graphite fiber layer that a layer thickness is 120 μm ~ 200 μm.
In the utility model, the inner side of described PVC retainer is also provided with groove, to facilitate linear bearing Integrated Chip and dust to be taken out of from groove in movement process, extends the working life of bearing.
In the utility model, inside described sleeve pipe and between retainer and ball, be also provided with one deck self-lubricating film, in order to improve the self-lubricating property of linear bearing, keep the sensitivity of bearing.
In the utility model, the wall thickness of described teflon shell is thick 1 ~ 1.5 times of wear-resistant ceramic inner tubal wall.
Beneficial effect: the utility model structure is simple, reasonable in design, larger radial direction, axially two-way connected load and torque load can be born, meanwhile, employ the shell that the teflon that is called as " King " is made, can effectively reduce bearing gross weight, coordinate self-lubricating film and PAN based graphite fiber interlayer effectively can improve the impact strength of bearing, reduce the wearing and tearing of ball, improve transmission accuracy, to reach the object extending bearing working life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Fig. 2 is the tangent plane schematic diagram of the utility model preferred embodiment.
Fig. 3 is the detailed schematic of A position in Fig. 2.
Wherein: 1, jump-ring slot; 2, sleeve pipe; 3, convex annular rank; 4, retainer; 5, ball; 6, groove; 7, self-lubricating film; 201, pipe in wear-resistant ceramic; 202, PAN based graphite fiber layer; 203, teflon shell.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See the preferred embodiment of taking off material machine linear bearing of Fig. 1, Fig. 2, Fig. 3, in the present embodiment, comprise retainer 4, sleeve pipe 2 and ball 5, ball 5 is arranged in retainer 4, and retainer 4 is made for PVC material, is installed in the pipe of sleeve pipe 2, and one deck self-lubricating film 7 is provided with between sleeve pipe 2, and groove 6 is provided with in the inner side of retainer 4, to facilitate linear bearing Integrated Chip and dust to be taken out of from groove in movement process, extend the working life of bearing.
Sleeve pipe 2 is three-layer composite pipe structure, three layers of composite bed are coaxially shaping, pipe 201, middle PAN based graphite fiber layer 202 and outer field teflon shell 203 in the wear-resistant ceramic comprising internal layer, wherein, the two ends in the outside of teflon shell 203 are respectively arranged with jump-ring slot 1 and convex annular rank 3, a jump-ring slot on this cancellation traditional line bearing, and the design that convex annular rank 3 are revised as in bottom effectively can be increased the lifting surface area of bearing, to bear weight and the impact of Ba Liao mechanism.
In the present embodiment, in wear-resistant ceramic in sleeve pipe 2, the wall thickness of pipe 201 is consistent with the wall thickness of teflon shell 203, and the thickness of PAN based graphite fiber layer 202 is 150 μm, PAN based graphite fiber layer 202 can realize the high strength and modulus standard of bearing, impact resistance is good, thermal expansion coefficient is little, simultaneously can effectively acid-and base-resisting corrosion.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
