Description
Technical field
The utility model relates to bearing manufacturing technology field, especially a kind of crossing cylinder roller turntable bearing.
Background technique
Existing crossing cylinder roller turntable bearing structure generally comprises: bearing outer ring, bearing inner race, cylindrical roller, spacing block, taper pin and cylindrical inserting.Cylindrically insert and open columniform bearing inner race and cooperate and locate with taper pin.As shown in Figure 1, cylindrical inserting from the cylindrical roller of radially packing into, spacing block.Not enough below this technological scheme exists: (1) cylindrical inserting made difficulty; When (2) assembling, from cylinder-shaped bearing inner ring (or bearing outer ring) dress roller holes, the cylindrical roller of packing into, spacing block.The operating space is narrow and small, is difficult to operation.Observation space is narrow and small, very easily should adjacent center be the cylindrical roller loading error of 90 ° of intercross arrangement, causes reject, and rigger and inspector are difficult to find error correction.Cause the final inflow terminal user of reject, cause unpredicted accident.
Summary of the invention
To the deficiency that existing technology exists, it is a kind of simple in structure that the purpose of the utility model is to provide, and easy processing, easy to assembly is difficult for makeing mistakes, and saves the crossing cylinder roller turntable bearing of steel again.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of crossing cylinder roller turntable bearing, and comprise bearing inner race assembly, bearing outer ring and be arranged on cylindrical roller and the spacing block between bearing inner race assembly and the bearing outer ring, offer outer raceway on the bearing outer ring; Said bearing inner race assembly comprises inner ring and following inner ring; Said upper and lower inner ring removably connects, and on upper and lower inner ring, offers interior raceway respectively, and said interior raceway and outer raceway are merged into the raceway of an integral body; Described cylindrical roller cross arrangement is distributed in the raceway, is separated by spacing block between adjacent two cylindrical rollers.
Through adopting technique scheme, reasonable in design, not only simple in structure, and structure processes easily, and easy to assembly, in the process of assembling, be difficult for makeing mistakes, saved steel again, reduce manufacture cost.
The utility model further is set to: said inner ring down is provided with screw, and said inner ring down removably connects through screw and last inner ring bottom.Through this setting, following inner ring and last inner ring are easy to assembly, and be simple to operate and be difficult for makeing mistakes.
The utility model also further is set to: said " V " font of going up the sectional shape of the interior raceway of offering after inner ring assembles with following inner ring for 90 ° of inclinations.Through this setting, reasonable in design, reliable operation.
The utility model also further is set to: the sectional shape of said outer raceway is " V " font relative with interior raceway, and said interior raceway is a square with the cross-section area of the whole raceway that outer raceway constitutes.Through this setting, the utility model work is more reliable.
The utility model has the advantages that: compare with existing crossing cylinder roller turntable bearing, last inner ring removably connects with following inner ring, and its structure is simpler, has saved steel, thereby reduces manufacture cost, and processing easily, and is easy to assembly, is difficult for makeing mistakes.
Below in conjunction with Figure of description and embodiment the utility model is further described.
