Description
Technical field
The utility model belongs to electrical engineering field, relates to a kind of cylindrical bearing outer ring removing device.
Technical background
According to electric driving machinery of subway service technique code, electric driving machinery of subway often runs 600,000 kilometers of Hou Xufan factory maintenance, and machinery check and repair process must dismantle bearings at both ends, and detects bearing.Cylindrical bearing outer ring is made up of retainer, outer ring and rolling element three parts, bearing outer ring and bearing chamber size are assembled into interference fits, and therefore how realizing reliable in bearing chamber, safe, efficient, undamaged the separating in cylindrical bearing outer ring is the problem that cylindrical bearing service technique, must solve.
Present stage electric driving machinery of subway maintenance is carried out in bearing removal process, cylindrical bearing outer ring removing device uses chuck to complete by hydraulic pressure draw-bar device, the method has following shortcoming: location difficulty in existing cylindrical bearing outer ring removing device assembly operation process, waste time and energy, once location occurs that the contact position lifting surface area of deviation card dish and roller is little, very easily damage bearing roller when extracting and retainer causes bearing to be scrapped, increase the cost of overhaul.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of deep-groove ball bearing dismantling device.By implementing the utility model, can solve in prior art and having that quality control difficulty is high, efficiency is low, the technical problem of poor stability, bearing removal easy damaged.
According to the utility model, technique scheme is realized by technical characteristic as described below: a kind of cylindrical bearing outer ring removing device, comprise bolt, hydraulic pump, pull bar, bracing frame, arm-tie and location snap ring, described arm-tie is provided with the locating hole of inside diameter-adjustable, described locating hole is for regulating the internal diameter of location snap ring, described location snap ring is fixed on arm-tie, described arm-tie is fastened on pull bar lower end, described hydraulic pump, bracing frame are sleeved on pull bar, hydraulic pump one end is fitted in above bracing frame, and other end fastening bolt is fastening.
Further, to be provided with several legs symmetrical for bracing frame.
Further, pull bar lower end is threaded, and chassis is connected with pull rod screw.
Further, pull bar length be greater than bearing width, bracing frame height, fastening bolt height and hydraulic pump height and.
Further, locate snap ring to be fixed by screws on arm-tie.
Further, on arm-tie, the locating hole of inside diameter-adjustable is elongated hole.
Further, location snap ring is semilune, is circumferentially provided with recessed draw-in groove.
Location snap ring is bolted on arm-tie, radial adjustment two locator card ring positions make location snap ring just in time be stuck on bearing outer ring ball, location snap ring is fixed on arm-tie by fastening bolt, pull bar is arranged on arm-tie, by bracing frame centre bore alignment pull bar, pull bar is passed through from bracing frame centre bore, bracing frame is lain on bearing block, bracing frame four legs to be symmetrically distributed on bearing block and to guarantee bearing drawing height, hydraulic pump head is sleeved on pull bar, hydraulic pump head one end is fitted in above bracing frame, other end special bolt is fastening, after fastening whole provision for disengagement, primer fluid press pump by cylindrical bearing outer ring from bearing indoor security, steadily, take apart reliably, snap ring can be radial movable to adapt to pull out different model cylindrical bearing outer ring.
It is simple that this device has structure, and use and maintenance is convenient, with low cost, is applicable to the advantages such as mass production.
