Description

Bearing with rolling bodies capable of being quickly assembled and disassembled Technical Field The application relates to the technical field of bearings, in particular to a bearing with a rolling body capable of being quickly assembled and disassembled. Background The belt conveyer is widely applied to a tobacco industry thread-making production line, and mainly drives a conveying belt to run at a high speed by a transmission shaft, and two ends of the transmission shaft are respectively connected and supported by a group of belt seat bearings. During the use of the equipment, the bearing needs to be disassembled regularly for performance inspection, the traditional bearing disassembling and inspecting mode is to disassemble connecting bolts, taper pins and other connecting pieces firstly, disassemble the bearing outer ring in a lifting manner, then inspect and replace internal parts such as a retainer and a rolling body, the process is complex and tedious, and the inspection and replacement are often carried out in the mode, so that the inspection and assembly efficiency of the bearing are lower. Disclosure of Invention The application provides a bearing with a rolling body capable of being quickly assembled and disassembled, which can solve or improve the problems of lower detection and assembly efficiency of the bearing without completely disassembling parts such as a connecting bolt, a taper pin, a bearing outer ring and the like when the rolling body is assembled and disassembled. The application provides a bearing with a rapidly-assembled rolling body, which comprises a bearing body, wherein the bearing body comprises a bearing outer ring, an assembling and disassembling groove is formed in the end face of the bearing outer ring, the assembling and disassembling groove is communicated with a rolling path where the rolling body is located, and a closing cover is detachably clamped in the assembling and disassembling groove and used for filling the assembling and disassembling groove. Through adopting above-mentioned technical scheme, when needs regularly dismantle the bearing body, examine again to inside spare parts such as holder, rolling element, dismantle the dismouting inslot that closes the cover from the bearing outer lane, can make rolling element and the holder that are located the raceway show out, take out the rolling element in the raceway in proper order, overhaul the maintenance to the rolling element of taking out, install the rolling element that overhauls the completion again or new rolling element in proper order back in the raceway of bearing body, will close the cover and install the dismouting inslot to the bearing outer lane again at last, in order to keep the integrality of bearing body. The process does not need to remove all parts such as the connecting bolts, the taper pins, the bearing outer ring and the like, simplifies the process of checking and replacing the internal parts such as the retainer, the rolling bodies and the like, and improves the checking and assembling efficiency of the bearing. In the above-mentioned alternative technical scheme of rolling element quick assembly disassembly bearing, the surface that closes the cover flushes with the terminal surface and the week side of bearing inner race. Through adopting above-mentioned technical scheme, will close after the dismouting groove of cover installation to the bearing outer lane, close cover and bearing body and become a complete whole, close cover and bearing body tight thread and close the seam, neither influence the aesthetic property of bearing body outward appearance, do not influence the normal operating of bearing body again. In the above-mentioned alternative technical scheme of rolling element quick assembly disassembly bearing, along the circumferencial direction of bearing outer lane, the both sides that close the cover all set up to the inclined plane. Through adopting above-mentioned technical scheme, owing to close the both sides of cover and all set up to the inclined plane, consequently close the inclined plane of dismouting groove on cover both sides and the bearing outer lane and press fit each other, including forming dovetail's assembly methods, also directly increased the area of contact who closes cover and bearing outer lane, can further increase the stability of closing the cover and installing on the bearing body.
