Abstract
The utility model discloses a bearing dismounting device, which comprises a threaded rod, wherein ejecting sleeves are respectively fixed above the threaded rod through a fixing nut, a jacket is arranged outside each ejecting sleeve, one end of the threaded rod is connected with an axial displacement nut, the other end of the threaded rod is provided with an assembling hole relative to the end on which the axial displacement nut is arranged, and a handle penetrates through the assembling hole to be arranged above the threaded rod. The bearing dismounting device drives the threaded rod to generate axial displacement through rotating the handle and stably ejects a bearing by utilizing the ejecting sleeves, so that the structure is simple, the operation is convenient and the dismounting efficiency is high, damage to the accuracy of the bearing during a dismounting process is effectively relieved, and the rejection rate of the bearing is reduced.
Description
Technical field
The utility model relates to a kind of bearing disassembling device.
Background technology
At present, in common bearing removal installation process, all be manually it to be knocked out by copper rod or other aids, this unloading process inefficiency, also make the bearing scrappage very high, the service precision of bearing reduces simultaneously, and product cost also improves greatly.
The utility model content
The purpose of this utility model is to provide a kind of bearing disassembling device, and it has simple in structure, the convenient to use and characteristics that greatly reduce the bearing removal scrappage.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of bearing disassembling device, it comprises screw rod, is fixed with ejector sleeve on the described screw rod, and an end of described screw rod connection axial displacement nut, and is connected with handle in the other end.
Described ejector sleeve is fixed on the screw rod by hold-down nut, and described ejector sleeve is outside equipped with sheath.
Described screw rod is provided with assembly hole with respect to the other end that the axial displacement nut is set, and described handle passes assembly hole and is arranged on the screw rod.
The beneficial effects of the utility model are:
1, mechanically replaced manually-operated, improved the removal efficiency of bearing;
2, effectively alleviated in unloading process the destruction of bearing accuracy, reduced the bearing scrappage.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of a kind of bearing disassembling device of the utility model;
Among the figure:
1, screw rod; 2, ejector sleeve; 3, hold-down nut; 4, axial displacement nut; 5, sheath; 6, screw; 7, handle; 8, assembly hole; 9, nut.
The specific embodiment
Please refer to shown in Figure 1; Fig. 1 is the structural representation of a kind of bearing disassembling device of the utility model; in present embodiment; a kind of bearing disassembling device; it comprises screw rod 1; be fixed with ejector sleeve 2 on the described screw rod 1; described ejector sleeve 2 is fixed on the screw rod 1 by hold-down nut 3; and be provided with sheath 5 by screw 6 outside the described ejector sleeve 2; described sheath 5 is used for protection ejector sleeve 2 during inoperative; side in ejector sleeve 2 on the described screw rod 1 is connected with axial displacement nut 4; the end of the opposite side screw rod 1 of described ejector sleeve 2 is provided with assembly hole 8; be installed with handle 7 in the described assembly hole 8, described handle 7 is provided with nut 9, comes off in assembly hole 8 to prevent handle 7.
During the dismounting bearing, at first, take off sheath 5, screw rod 1 is passed the through hole of bearing centre again, make ejector sleeve 2 fit tightly bearing, then, turning handle 7 makes screw rod 1 produce axial displacement, and screw rod 1 drives ejector sleeve 2 simultaneously and moves, and steadily ejects bearing by ejector sleeve 2.
Above-mentioned bearing disassembling device has mechanically replaced manually-operated; The removal efficiency that has improved bearing by very havoc, and has obtained effective alleviation in the past unloading process middle (center) bearing precision in this device use, reduced scrappage.
