Abstract
The utility model provides a bearing changing tool which consists of a screw rod, a fixed disc and three pulling claws, wherein the fixed disc and the screw rod form into a screw rod driving structure, the three pulling claws are fixed on the fixed disc by screw bolts, each pulling claw arm is in an outward arc structure, and the three pulling claws are distributed at an equivalent angle. A tip at the front end of each pulling claw is fastened on the end face of a bearing, and the axial movement is realized by rotating the screw rod, so that the aim of disassembly can be achieved. The bearing changing tool is simple in structure, easy to manufacture, convenient to operate and use, time-saving, labor-saving, safe, and high in work efficiency; as the pulling claws adopt the arc structures, the factors for triggering the safe accidents such as the unbalance loading, the side slipping, the breaking or the straightening of the screw rod and the pincers claws and the like can be effectively avoided due to the characteristic of force application; and an ideal effect can be achieved under the condition that the cost is very low.
Description
Technical field
The utility model relates to the bearing removal tool special of a kind of industrial and mining enterprises widespread usage.
Background technology
Present known bearing is removed and adopted destructive the dismounting and two kinds of methods of protectiveness dismounting: destructive dismounting can utilize several different methods such as gas cutting, hammering to remove; And some bearing is when also having the value of recycling, and just needs employing specific purpose tool carries out the protectiveness dismounting; Even no longer utilizing, some bearing do not allow must utilize to draw horse to remove owing to environment yet.It is various informative that the market upper bearing (metal) is changed instrument now, draw horse and draw horse manually as hydraulic pressure, hydraulic pressure draws that horse all has the cost height, bad and environment for use such as is limited at shortcoming easily, and manually draws horse that easy unbalance loading is arranged, cause screw mandrel, chela to fracture or stretching, cause the shortcoming of security incident.
Summary of the invention
The purpose of this utility model is a kind of unbalance loading that prevents of design, and laborsaving, the bearing replacing instrument of applied range, thus eliminate safe hidden trouble, reach the maintenance purpose.
Implementation procedure of the present utility model is such: it is made up of screw mandrel, fixed disk and three pulling claws, fixed disk and screw mandrel are formed the screw mandrel drive mechanism, three pulling claws by bolting to fixed disk, so that adjust the size of pulling claw opening, the pulling claw arm is an outside arcuate structure, and three pulling claw equal angles distribute.The tip of pulling claw front end is anchored on the bearing face, realizes axial displacement by rotary screw rod, thereby reaches the dismounting purpose.
The arc tangent line of pulling claw pawl arm is parallel with screw mandrel.
Good effect of the present utility model is: simple in structure, easy to manufacture, easy for operation, and time saving and energy saving safety again, high efficiency; Because this pulling claw adopts arcuate structure, utilizes stressed characteristics, can effectively avoid unbalance loading, sideslip and screw mandrel, chela to fracture or stretching etc. caused the factor of security incident; Be issued to desirable effect in the very low situation of cost.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, this bearing replacing instrument is made up of screw mandrel 1, fixed disk 2 and three pulling claws 3, and fixed disk 2 and screw mandrel 1 are formed the screw mandrel drive mechanism, and pulling claw 3 pawl arms are outside arcuate structures, and the arc tangent line of pawl arm is parallel with screw mandrel 1; Three pulling claw 3 equal angles distribute, and thread off to prevent pulling claw 3; Be the convenient size of adjusting pulling claw 3 openings, pulling claw 3 is fixed on the fixed disk 2 by bolt 4, and the bearing of dismounting different-diameter can outwards or inwardly be adjusted the folding degree of pulling claw 3 and adjusts by unclamping bolt 4; Six pore structures in adopt screw mandrel 1 upper end can extend when length is not enough.
When needs with bearing when axle is extracted, pulling claw 3 is fixed on the end face of bearing by adjusting angle, push up in the fabrication hole of axle at the tip of leading screw 1, rotary screw rod 1 realizes that axial displacement just can extract bearing, thereby reaches the dismounting purpose.
Claims (2)
1. bearing replacing instrument, it is characterized in that: it is made up of screw mandrel, fixed disk and three pulling claws, and fixed disk and screw mandrel are formed the screw mandrel drive mechanism, three pulling claws by bolting to fixed disk, the pulling claw arm is an outside arcuate structure, and three pulling claw equal angles distribute.
2. bearing replacing instrument according to claim 1 is characterized in that: the arc tangent line of pulling claw pawl arm is parallel with screw mandrel.
