The utility model relates to a combined sleeve of closely-arranged rolling bodies, which comprises an internal assembly sleeve, an external assembly sleeve and two side covers, wherein the external assembly sleeve is coaxially arranged outside the internal assembly sleeve, a cavity for arranging a rolling body group is arranged between the inner ring of the external assembly sleeve and the outer ring of the internal assembly sleeve, assembly shafts extending in the two side covers are pressed on the inner ring of the internal assembly sleeve, and the outer rings of the two side covers are arranged between the outer ring of the internal assembly sleeve and the inner ring of the external assembly sleeve. The combined sleeve can conveniently assemble the rolling bodies between a gear and an intermediate shaft, thus greatly improving the assembly efficiency and quality.
Description
Technical field
The utility model relates to a kind of combination cover that is used for solid matter type rolling element, belongs to the hub bearing technical field.
Background technique
In the multiaxis speed changer of vehicle,,, make vehicle have suitable tractive force and speed to change the moment of torsion and the rotating speed of motor by the driving gear transmission of variant velocity ratio in the gearbox casing.And some jack shafts that are installed on the gearbox casing adopt revolute axes configuration, and needle bearing promptly is installed between driving gear and the jack shaft, and the typical case is as also being equipped with needle bearing between planetary pinion and the planet axis.Under the constant prerequisite of each jack shaft centre distance of speed changer, increase along with the speed change gear, the needle bearing that is installed on driving gear and the jack shaft does not have the outer ring by no inner ring structural development to both there being inner ring yet, therefore only needle roller is installed between gear hole and the jack shaft.But the above-mentioned needle bearing that is installed between gear and the jack shaft does not have inner ring and outer ring, during installation, each rolling element is arranged by hand in the gear hole and with lubricant grease and is adsorbed in the gear hole, refill and be fitted on the jack shaft, since twice hand assembled, complicated operation, and easily cause dropping of rolling element, influence assembly precision, thereby reduce the working life of bearing.Moreover the both sides of some roller bearings also need the side packing ring, have further increased the complexity of bearing assemble, affect packaging efficiency and the installation quality of gearbox.In addition, because roller is to deposit by FCL, take out again during installation, because each roller does not have position-limit mechanism, easily make needle roller drop and cause damage during on-the-spot the installation.
Summary of the invention
The purpose of this utility model provides and a kind ofly makes things convenient for rolling element assembling to join, and improves efficiency of assembling and quality, deposits the combination cover of solid matter type rolling element easily.
The utility model is that the technical scheme that achieves the above object is: a kind of combination cover of solid matter type rolling element, it is characterized in that: comprise interior assembly set, outer assembly set and two side covers, described outer assembly set is coaxially set in the outside of interior assembly set, and be the cavity that the rolling element group is installed between the inner ring of outer assembly set and the outer ring of interior assembly set, the assembled shaft of stretching in two side covers is crimped on the inner ring of interior assembly set, and the outer ring of two side covers is between the inner ring of the outer ring of interior assembly set and outer assembly set.
Wherein: described interior assembly set is provided with elastic opening vertically.
The length of described interior assembly set is greater than the length of outer assembly set.
Described both sides cover also has inner cover plate, and inner cover plate is provided with the aperture.
The structure of assembly set and outer assembly set in the utility model adopts, rolling element group and packing ring can be installed in earlier between interior assembly set and the outer assembly set, and two side covers are crimped on the interior assembly set, make interior assembly set by the rolling element group, the structure of outer assembly set and an integral body of two side cover formations, can conveniently store each group rolling element, and in assembling process, to make up earlier cover and be placed on gear hole one side, to make up cover pushes in the gear hole, simultaneously outer assembly set is turned down, convenient be installed in the gear hole the rolling element group is disposable, and in jackshaft is installed in gear hole the time, only need two side cover is removed, when being installed in jackshaft on the gear, turn down interior assembly set by the shaft shoulder of jackshaft, the rolling element group is installed in jackshaft and the gear hole, the utility model will be placed on the interior rolling element group of combination cover by twice installation by the combination cover, between rolling element group integral installation gear hole and jackshaft, because the rolling element group reliably is installed in its raceway, can not cause assembly precision to descend, improve the efficiency of assembling of whole rolling element group.The utility model is installed in the rolling element group in the combination cover, not only be convenient to transportation storage, and be after being pressed into the rolling element group between gear hole and the jackshaft when installing, just will make up and overlap complete removal, when thoroughly having solved assembled in situ, the problem that single rolling element drops.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is with structural representation of the present utility model.
Wherein: 1-assembles cover outward, assembling cover in the 2-, 3-side cover, 31-assembled shaft, 32-inner cover plate, 33-aperture, 4-rolling element group, 5-back-up ring.
Embodiment
See shown in Figure 1, the combination cover of solid matter type rolling element of the present utility model, comprise interior assembly set 2, outer assembly set 1 and two side covers 3, outer assembly set 1 is coaxially set in the outside of interior assembly set 2, and be the cavity that rolling element is installed between the outer ring of the inner ring of outer assembly set 1 and interior assembly set 2, can be as shown in Figure 1, two row rolling element groups 4 are installed in interior assembly set 2 and the outer assembly set 1, or two between the row rolling element and both end sides back-up ring 5 all is installed, the assembled shaft 31 of stretching in two side covers 3 is crimped on the inner ring of interior assembly set 2, and the outer ring size of two side cover 3 cover plates is between the inner ring of the outer ring of interior assembly set 2 and outer assembly set 1, when rolling element group 4 is installed between interior assembly set 2 and the outer assembly set 1, by two side covers 3 interior assembly set 2 is connected with outer assembly set 1, and by two side covers 3 rolling element group 4 can not be deviate from.The utility model is the machining accuracy that reduces interior assembly set 2 and the assembling that makes things convenient for rolling element group 4, interior assembly set 2 is provided with elastic opening vertically, by assembly set 2 in assembled shaft 31 spreadings on the side cover 3, the length of assembly set 2 is greater than the length of outer assembly set 1 in the utility model, the convenient cover that will make up is pressed in the gear hole, also has inner cover plate 32 on the utility model two side covers 3, and inner cover plate 32 is provided with aperture 33, be convenient in assembling process, by easily side cover 3 being extracted manually, convenient to operation.
