Description

A kind of disassembling apparatus of general shaft end tapered roller bearing
Technical field
The utility model relates to tearing open for modern precision mounting technology field, especially a kind of general shaft end tapered roller bearing Solve device.
Background technique
Tapered roller bearing is widely used in the industries such as automobile, milling train, mine, metallurgy, plastics machinery.In sea, land and sky, day Etc. equipment fields, precision equipment use it is also very much.Shaft end uses tapered roller bearing, is mainly used for receiving with radial load and is Main radial direction and axial connected load, large carrying capacity, limit speed is low.Tapered roller bearing is able to bear the axis in a direction To load, the axial displacement in one direction of axis or shell can be limited.
The precision assembly of one product determines the quality of this product, and for scientific research project, the quality of assembly is decide This project at lose, the assembly precision of shafting product requires very high, and shafting adjustment is the core component of any equipment, precision Quality directly determine equipment transmission accuracy, so shaft dimension chain equipment adjustment requirement it is very high.The shafting installed Component needs to disassemble analysis by the scientific experiment of several wheels, and the tightness degree of each bearing on axis is very high, really up to the mark to match Conjunction is especially tight, and the adjustment of tapered roller bearing end-play is very good, and interference fit very little, general tooling is difficult to be disassembled, Repeatedly fail during experiment, the tapered roller bearing removed cannot be intact, and tapered roller body directly falls apart, and has Retainer deformation, directly affects the subsequent performance evaluation to bearing, influences the data analysis of scientific research and testing.
How to realize that intact dismantling is extremely important to subsequent experimental analysis.How precision assembly and precision realized Disassemble shaft class product requirement it is very high, importance as one can imagine.
Utility model content
The purpose of this utility model is that providing a kind of difficulty that can reduce dismantling in place of making up the deficiencies in the prior art Degree, guarantee tapered roller bearing precision and data analysis that is complete, meeting scientific research and testing, reduce cost, improve efficiency it is general The disassembling apparatus of shaft end tapered roller bearing.
The purpose of this utility model is realized by following technological means:
A kind of disassembling apparatus of general shaft end tapered roller bearing, it is characterised in that: including opposite opened closing piece, locating support And thread lead screw, it produces for installing the locating slot for placing workpiece to be dismantled inside opposite opened closing piece;The upper end spiral shell of locating support Line engagement installation thread lead screw, the thread lead screw are vertically arranged and are coaxially disposed with locating slot made inside opposite opened closing piece; The lower end of locating support is mounted on opposite opened closing piece.
Moreover, the locating support is made of a upper beam and two side plates, thread lead screw is mounted on upper beam; Two side plates are separately mounted to the lower part of the left and right sides of upper beam, and the lower part of two side plates is separately mounted to opposite opened closing piece Opening.
The advantages and positive effects of the utility model are as follows:
The utility model passes through the lossless dismantling tapered roller bearing of frock clamp, it is ensured that required precision improves assembly essence Degree and efficiency meet the requirement of high-precision and long life.
This achievement mentality of designing is ingenious, has novelty, provides a kind of dismantling dress of general shaft end tapered roller bearing It sets and method, the difficulty of dismantling can be reduced using the present apparatus and method, guarantee tapered roller bearing precision and complete, meet scientific research The data of test are analyzed, and are reduced cost, are improved efficiency, and guarantee product quality, have promotional value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of disassembling apparatus;
Fig. 2 is the structural schematic diagram of disassembling apparatus working principle.
Figure label are as follows:
1, tapered roller bearing;2, opposite opened closing piece;3, locating support;4, thread lead screw;5, axis.
Specific embodiment
Embodiment of the utility model will be described in detail below with reference to the attached drawings, it should be noted that the present embodiment is narrative , it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of disassembling apparatus of general shaft end tapered roller bearing, including opposite opened closing piece 2, locating support 3 and screw thread silk Thick stick 4 is produced inside opposite opened closing piece for installing the locating slot for placing workpiece to be dismantled, and opposite opened closing piece rolls the circular cone of shaft end Inner ring, tapered roller body and the retainer of sub- bearing are locked by soket head cap screw, and various sizes of tapered roller bearing is selected Various sizes of opposite opened closing piece.
Locating support is made of a upper beam and two side plates, and the engagement of thread lead screw screw thread is mounted on upper beam, should Thread lead screw is vertically arranged and is coaxially disposed with locating slot made inside opposite opened closing piece.Two side plates are separately mounted to cross The lower part of the left and right sides of beam, the lower part of two side plates are separately mounted to the opening of opposite opened closing piece.Locating support is to spiral shell Line lead screw one support, the top of thread lead screw is located in and is consistent with 5 axis of main shaft.Thread lead screw is by the rotation of lead screw Transhipment turn becomes to move along a straight line.
The application method of the utility model are as follows:
Shaft assembly equipped with tapered roller bearing 1 is removed from the device, it is independent, it removes bearing outer ring and carries out mark Note;The tapered roller bearing of the rolling element to connect together with bearing inner race is locked using special tooling structural member opposite opened closing piece Firmly, closing piece is tightened using soket head cap screw, locating support is installed in the opening direction of opposite opened closing piece, by the top of thread lead screw End is screwed in from the top of locating support;It is transformed into lead screw straight reciprocating by the rotation of the thread lead screw on locating support, Lead screw is screwed in, the top of thread lead screw is withstood in the plane of shaft end, the straight line of closing piece is converted into using the rotary motion of screw rod It is mobile, drive tapered roller bearing mobile, until being removed, it is ensured that tapered roller bearing it is intact.
