Abstract
A special puller for a bearing comprises a pull disk, puller bolts and two pull arms. Hooks extending outwards and corresponding to a bearing outer ring in position are arranged at the front ends of the two pull arms, the rear ends of the two pull arms are mutually hinged, at least two puller bolts are circumferentially arranged on the pull disk in a screw joint manner, the pull disk is radially provided with a rectangular hole, a supporting block is arranged at the center of the rectangular hole, the front halves of the two pull arms penetrate into the rectangular hole, the supporting block is positioned between the two pull arms and is in the shape of a trapezoidal table with a large front and a small rear, the surface of each of an upper waist and a lower waist of the supporting block is closely attached to the corresponding pull arm in a supported manner, and symmetric stepped notches which can be mutually matched are arranged at the rear ends of the two pull arms respectively and are mutually fastened in a staggered manner and hinged. The special puller for the bearing is simple in structure, practical in functions, capable of greatly facilitating replacement of carrier roller bearings, time-saving and labor-saving, and mounting and demounting efficiency is greatly improved.
Description
Technical field
The utility model relates to the special-purpose chest expander of a kind of bearing.
Background technology
The idler for belt conveyer drive bearing is 6204 types at present, when bearing needs to remove in the appearance wearing and tearing, the phenomenon that bearing outer ring and retainer break away from can occur; Taking out comparatively difficulty, when meeting this situation, generally is to insert from the carrying roller other end with steel pipe; Bearing outer ring is got, because the outer ring wall thickness has only 2 ~ 3mm, roller carrier shaft bearing inwall also has the bearing limit base; When using the method to get the outer ring, time-consuming, effort.
The utility model content
The utility model purpose is to provide a kind of bearing special-purpose chest expander, is very easy to the replacing of Idler bearing, saves time, laborsaving.
To achieve these goals; The utility model adopts following technical scheme: the special-purpose chest expander of a kind of bearing; Comprise pulling force disk, puller bolt and two pulling force arms; The front end of two pulling force arms is provided with the coupler body corresponding with the bearing outer ring position that stretches laterally, and the rear end of two pulling force arms is hinged; Be spirally connected at least in one week of pulling force disk and be provided with two puller bolts, radially be provided with a slot on the pulling force disk, the central authorities of slot are provided with back-up block, the first half of two pulling force arms penetrate in the slot and back-up block between two pulling force arms.
Described back-up block is pre-large post-small bucking ladder, and the face at the upper and lower two waists place of back-up block reclines to support with the pulling force arm respectively and is provided with.
The rear end of described two pulling force arms is respectively equipped with the breach of the trapezoidal shape of the symmetry that can cooperatively interact, interlaced fastening of the breach of two pulling force arms and hinged setting.
Described pulling force arm is processed by carbon steel material.
The long 100mm of described pulling force arm, thick 10mm; Described pulling force disk diameter 65mm, thick 10mm.
The utility model is simple in structure, function is practical, can be very easy to the replacing of Idler bearing, saves time, laborsaving, has improved removal efficiency greatly.

The specific embodiment
Embodiment: shown in Fig. 1-8; The special-purpose chest expander of a kind of bearing; Comprise pulling force disk 4, puller bolt 3 and two pulling force arms 5,6; The rear end that the front end of two pulling force arms 5,6 is provided with laterally corresponding 10,11, two the pulling force arms 5,6 of coupler body in bearing outer ring 2 positions with in the frame 1 of stretching is hinged; Be spirally connected at least in 4 one weeks of pulling force disk and be provided with two puller bolts 3; Radially be provided with a slot 12 on the pulling force disk 4; The first half that the central authorities of slot 12 are provided with 7, two pulling force arms of back-up block 5,6 penetrate in the slot 12 and back-up block 7 at two pulling force arms 5, between 6.Back-up block 7 is pre-large post-small bucking ladder, and the face at the upper and lower two waists place of back-up block 7 reclines to support with pulling force arm 5,6 respectively and is provided with.The rear end of two pulling force arms 5,6 is respectively equipped with breach 8,9 interlaced fastenings and the hinged setting of 8,9, two pulling force arms 5,6 of breach of the trapezoidal shape of the symmetry that can cooperatively interact. Pulling force arm 5,6 is processed by carbon steel material.
During practical implementation, pulling force arm 5,6 makes two square steel that 100mm is long, 10mm is thick, and an end buckle contacts with bearing outer ring, and other end band silk hole is convenient to two square steel and is cross-linked to form intersection, the pulling force disk diameter 65mm that is used, and thick 10mm.Have symmetrical 8mm silk hole to do the puller bolt hole on the pulling force disk 4, screw pushes up to the carrying roller outer wall.Have the wide rectangular slot of 12mm of symmetry in the middle of the disk, have bucking ladder, the length of side to be respectively 10mm, 6mm in the middle of two elongated slots; Dovetail groove supports the intersection square steel; When puller bolt held out against the carrying roller outer wall, dovetail groove tensioner square steel buckle outwards stretched on one side, thereby pulls out bearing outer ring.
During use; The fore paw of chest expander pulling force arm 5,6 is goed deep into 2 places, frame 1 inner bearing outer ring; And reliably contact with bearing outer ring 2, through rotating puller bolt 3, pulling force disk 4 is moved to the right; Taper platform on the pulling force disk 4 drives pulling force arm 5,6 again and moves to the right, thereby bearing outer ring 2 is taken out.
