More preferably, the limit assembly is set as guide blot, is provided on the side wall of the pressure head ontology and leads with described
The threaded hole to match to bolt, limiting slot is correspondingly provided on the inner ring pressure head, and the guide blot runs through the spiral shell
Pit extends in the limiting slot.
More preferably, the limiting slot is set as keyway, and the length of the keyway is greater than the maximum compressibility of the disc spring.
More preferably, the centre bore to match with gear shaft is provided on the firm banking.
Compared with the prior art, the beneficial effects of the utility model are: 1, by pressure head ontology, disc spring, inner ring pressure head with
And the mutual assembling cooperation of guide blot, the pressure size being applied on bearing inner race can be made suitable in this way, to avoid bearing
Inner ring, raceway deform, and then prevent speed changer from the problems such as abnormal sound, utter long and high-pitched sounds occur, and improve the use peace of speed changer
Full property and comfort.2, it is not only simple in structure, rationally, it is easy to operate, reliable, and it is pressed high-efficient, low manufacture cost, it is general
Property is strong, meets the needs of speed changer assembly line.
Detailed description of the invention
Fig. 1 is a kind of overall structure diagram of gear shaft shoulder bearing inner race press-loading apparatus of the utility model.
Fig. 2 is pressure head ontology, disc spring, the assembling schematic diagram of inner ring pressure head and guide blot in the utility model.
It illustrates: 1- pressure head ontology, 101- threaded hole, 2- disc spring, 3- inner ring pressure head, 301- bearing inner race accommodating chamber,
302- gear shaft mating cavity, 303- limiting slot, 4- guide blot, 5- firm banking, 6- gear shaft.
Specific embodiment
The utility model is further described with preferred embodiment with reference to the accompanying drawing.
It is as illustrated in fig. 1 and 2 a kind of structural schematic diagram of gear shaft shoulder bearing inner race press-loading apparatus of the utility model, packet
Include pressure head ontology 1, disc spring 2, inner ring pressure head 3, guide blot 4 and firm banking 5.Wherein, pressure head ontology 1 can be connected through a screw thread
Mode is mounted on the pressure head of press.Disc spring 2 and inner ring pressure head 3 are installed in the inside of pressure head ontology 1, in pressure head ontology 1
Side is equipped with guide blot 4, which can limit inner ring pressure head 3 and slide up and down in pressure head ontology 1, specifically
It is that the threaded hole 101 to match with guide blot 4 is provided on the side wall of pressure head ontology 1, and in the corresponding of inner ring pressure head 3
Limiting slot 303 is provided on position, one end of guide blot 4 can extend in limiting slot 303 through threaded hole 101, so both
It can prevent disc spring 2 and inner ring pressure head 3 from skidding off pressure head ontology 1, and sliding of the inner ring pressure head 3 in pressure head ontology 1 can be limited
Stroke.In the present invention, above-mentioned limiting slot 303 is set as keyway, and so that the length of keyway is greater than the maximum of disc spring 2 and press
Contracting amount, and the extruding force range of above-mentioned disc spring 2 has demarcated by pressure sensor in advance, and can guarantee in this way will be in bearing
Circle is correctly press-fit into place and does not damage bearing inner race.The bearing inner race of connection is also coaxially disposed in the bottom of inner ring pressure head 3
Accommodating chamber 301 and gear shaft mating cavity 302, bearing inner race can be previously positioned in bearing inner race accommodating chamber 301 in this way and
Convenient for bearing inner race is installed to gear shaft shoulder.The underface of pressure head ontology 1 is provided with firm banking 5, the firm banking 5
On be provided with the centre bore to match with gear shaft 6.In the present invention, firm banking 5 can be mounted on to the work of press
On platform.
The working principle of the utility model is as follows:
The bottom of gear shaft 6 is fixed on firm banking 5, bearing inner race to be pressed is placed in the axis of inner ring pressure head 3
It holds in inner ring accommodating chamber 301；Then by the top axle journal of pressure head general alignment gear shaft 6, start press, make press upper pressure head to
Lower movement, until the bottom surface of pressure head ontology 1 and inner ring pressure head 3 is resisted against on the top surface of gear shaft 6；Press continues to move down,
Pressure head ontology 1 also continues to move down until be resisted against on the gear face of gear shaft 6, and inner ring pressure head 3 and to pressing bearing
Inner ring is only sleeved at the top axle journal of gear shaft 6, and the disc spring 2 in pressure head ontology 1 is in most compressed state at this time；Press is slow
Slowly it moves up, inner ring pressure head 3 and bearing inner race can continue to move down under the action of the restoring force of disc spring 2, until by axis
It holds inner ring to be correctly press-fit into place, completes the press fitting of gear shaft shoulder bearing inner race at this time.
The above only expresses preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not
Therefore it can be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill people of this field
