Description
Technical field
The utility model relates to shaft coupling technical field, particularly relates to the general expansion sleeve frock of a kind of shaft coupling experiment of dynamic balancing.
Background technology
Shaft coupling is in quality inspection process, and having one important quality inspection project " part transient equilibrium inspection ", is that when High Rotation Speed, Oscillation Amplitude meets standard in order to ensure that shaft coupling in use.The inspection method of present use has walked to be placed on special dynamic balancing machine by ining succession to simulate duty, measures and correct vibration.And part is placed on dynamic balancing machine be need a kind of connecting toolings.Used the simple frock of " fluting plug+key block " in the past, because plug external diameter and shaft coupling endoporus need tolerance fit and roughness requirements, and in order to reduce the experimental error loosening and cause, both tolerance fit are tighter, cumbersome when causing handling, if shaft coupling both sides endoporus is not of uniform size, plug also needs to carry out cooperation and makes, same plug cannot be used for overlapping shaft coupling more, and this also result in waste.
Utility model content
According to above deficiency, the utility model provides that a kind of structure is simple, the general expansion sleeve frock of shaft coupling experiment of dynamic balancing of convenient disassembly.
For achieving the above object, the general expansion sleeve frock of the utility model shaft coupling experiment of dynamic balancing, main contents are: comprise plug, briquetting, upper bearing block, lining, upper expansion sleeve, middle bearing block, contiguous block, packing ring, lower bearing block and lower expansion sleeve, there is a positioning step described plug lower end, gasket sleeve is on plug and lower end withstands on the step of plug, two lower expansion sleeves are separated by lower bearing block and are enclosed within packing ring together, wherein the lower expansion sleeve of downside is fixed on the step of packing ring lower end, contiguous block is enclosed within plug and lower end and withstands on the upper surface of the lower expansion sleeve of upside, two upper expansion sleeves are separated by middle bearing block and are enclosed within plug together, wherein the lower surface of the upper expansion sleeve of downside withstands on the upper surface of contiguous block, lining is enclosed within plug and lower surface and withstands on the upper surface of the upper expansion sleeve of upside, upper bearing block is enclosed within plug and lower surface and withstands on the upper surface of lining, briquetting is enclosed within plug upper end, briquetting radial direction is furnished with lock-screw, briquetting is axially furnished with set screw, and set screw lower end withstands on the upper surface of bearing block.The utility model structure is simple, and cost is low, and convenient disassembly.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1-plug, 2-briquetting, the upper bearing block of 3-, 4-village is overlapped, the upper expansion sleeve of 5-, bearing block in 6-, 7-contiguous block, 8-packing ring, bearing block under 9-, expansion sleeve under 10-.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
These system main contents are: comprise plug 1, briquetting 2, upper bearing block 3, lining 4, upper expansion sleeve 5, middle bearing block 6, contiguous block 7, packing ring 8, lower bearing block 9 and lower expansion sleeve 10, there is a positioning step described plug 1 lower end, packing ring 8 is enclosed within plug 1 and lower end and withstands on the step of plug 1, two lower expansion sleeves 10 are separated by lower bearing block 9 and are enclosed within packing ring 8 together, wherein the lower expansion sleeve 10 of downside is fixed on the step of packing ring 8 lower end, contiguous block 7 is enclosed within plug 1 and lower end and withstands on the upper surface of the lower expansion sleeve 10 of upside, two upper expansion sleeves 5 are separated by middle bearing block 6 and are enclosed within plug 1 together, wherein the lower surface of the upper expansion sleeve 5 of downside withstands on the upper surface of contiguous block 7, lining 4 is enclosed within plug 1 and lower surface and withstands on the upper surface of the upper expansion sleeve 5 of upside, upper bearing block 3 is enclosed within plug 1 and lower surface and withstands on the upper surface of lining 4, briquetting 2 is enclosed within plug 1 upper end, briquetting 2 radial direction is furnished with lock-screw, briquetting 2 is axially furnished with set screw, and set screw lower end withstands on the upper surface of bearing block 3.
Described packing ring 8 is the ring flange of a band cylindrical hole.
The general expansion sleeve frock of the present embodiment shaft coupling experiment of dynamic balancing, by on trade union college to frock time, the endoporus one of shaft coupling two and half is enclosed within lower expansion sleeve 10, one is enclosed within expansion sleeve 5, owing to not applying pressure, at this moment there is larger gap between expansion sleeve and endoporus, can easily workpiece be put.Screw hole briquetting 2 having three axis uniform and the screw hole of four radial equipartitions; On cover after workpiece, briquetting 2 is enclosed within plug 1, tightens the screw in radial direction, briquetting 2 is fixed on plug 1.Then turn the screw on axial bolt hole again, make it push down bearing block 3; Upper bearing block 3 can transfer the pressure on expansion sleeve, and at this moment expansion sleeve cylindrical can swell under the effect on inclined-plane, and internal diameter reduces simultaneously; The cylindrical of swell can be fitted the endoporus of shaft coupling, and the internal diameter reduced can lock plug 1, so just reaches the object eliminating gap transmitting torque simultaneously; Screw on briquetting 2 turns the pressure that can produce about 3 tons by spanner, snap-in force can meet experiment needs completely, can not produce skidding between shaft coupling and plug; Experiment is loosened the axial bolt of briquetting, can be made expansion sleeve resilience after finishing, and recovers gap, for convenience detach.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
