Abstract
The utility model provides a bearing puller, which is composed of a screw rod, a connecting rod and two puller rods, wherein the screw rod is in threaded connection with the connecting rod. The two puller rods are respectively sheathed on both ends of the connecting rod. The inner side of the lower end of each puller rod is provided with a puller paw, and a screw bolt is arranged between corresponding puller paws on the two puller rods. The utility model is more convenient and labor-saving than the general puller during use, which enhances the maintenance efficiency and saves the maintenance cost.
Description
(1) technical field:
The utility model relates to the extracting tool that plant equipment middle (center) bearing, belt pulley etc. are installed in the parts on the axle.
(2) background technology:
It is general with taking off the son dismounting that plant equipment middle (center) bearing, belt pulley etc. are installed in parts on the axle, and the at present general son of taking off has two pawls or three-jaw, is made up of screw rod, connecting rod and jaw, and screw rod is connected with connecting rod spiral shell mosquito, on the jaw and rod hinge connection, can rotate around connecting rod.In our maintenance of equipment work at ordinary times, run into such problem through regular meeting: during the less parts (as the inner ring of needle bearing, less sprocket wheel etc.) of the diameter on dismounting axle, the used at ordinary times son of taking off has no usage, and the one, because the chi ` of jaw is improper, take off incessantly parts; The 2nd, because sometimes with general when taking off son and taking off parts, its centripetal force that provides is not enough, exerts oneself at the beginning, jaw is promptly thrown off, and uses inconvenience, inefficiency.At this moment, can only use the method for gas cutting that parts are carried out destructiveness and tear open, gas cutting flame affects to axle like this, and parts are destroyed, can't utilize again, causes waste.
(3) summary of the invention:
The utility model provides bearing a kind of easy to use, time saving and energy saving to take off son at the deficiencies in the prior art.
The utility model adopts following solution:
Bearing is taken off son and is made up of screw rod, connecting rod and gin pole, and screw rod is connected with connecting rod spiral shell mosquito, and gin pole has two, is set in the connecting rod two ends, and inboard, gin pole lower end is provided with jaw, is provided with bolt between the jaw of correspondence on two gin poles.
During use, can regulate two positions of gin pole on connecting rod, after jaw blocks parts, tighten the bolt on the jaw, make jaw tightly block parts according to the size of taking off parts diameter.Just can by rotary screw parts such as bearing be taken off down as using the common son of taking off.
The utility model uses more convenient, more laborsaving than the general son of taking off.Improve maintenance efficiency, saved maintenance cost.

(5) specific embodiment:
Embodiment:
Fig. 1 has provided structural representation of the present utility model.Bearing is taken off son and is made up of screw rod 1, connecting rod 2 and gin pole 3, and the middle part of connecting rod 2 has internal thread, screw rod 1 with should be connected by interior spiral shell mosquito, bull stick 6 is housed on it.Gin pole 3 has two, is set in the two ends of connecting rod 2, can move on connecting rod 2.Each inboard, gin pole 3 lower end is welded with between the jaw corresponding on 4, two gin poles 3 of two jaws and is provided with bolt 5 (referring to Fig. 2).In order to increase jaw 4 and the contact area of being taken off parts, and can be used in less taking off and unload the space, the fastener position employing thin plate of gin pole 3 is designed to concave shaped, and less like this parts (as less needle bearing inner ring) also can be stuck.For reaching certain rigidity, each parts carries out Quenching Treatment, and hardness reaches HRC41-42.During use, can regulate two positions of gin pole 3 on connecting rod 2, after jaw 4 blocks parts, tighten the bolt 5 on the jaw 4, make jaw 4 tightly block parts according to the size of taking off parts diameter.Tight a bolt after 5, just can be as using the common son of taking off, rotation bull stick 6 rotates screw rod 1, and parts are taken off down.That the utility model is applied to is less on the equipment axis class, tight parts take off unload more convenient, more laborsaving.
Claims (1)
