Abstract
The utility model relates to a bearing inner-ring puller, which comprises adjusting screws, a main body, pin shafts, a threaded rod and pulling rods, wherein the pulling rods are connected onto the crossbeam of the main body through the pin shafts, the two pulling rods and the two pin shafts are respectively and symmetrically installed, the adjusting screws are installed on the vertical branches of the main body, the two adjusting screws are symmetrically installed, the male thread of the threaded rod is screwed with the female thread on the main body, and the lower end of each pulling rod is provided with a transverse branch. After a bearing inner ring is hung by the transverse branch at the lower end of each pulling rod, the bearing inner ring can be disassembled by rotating the threaded rod, and the utility model saves time and labor when in disassembly, has low labor intensity of workers and good safety, can not damage a bearing and has remarkable economic benefit and social benefit.
Description
Technical field:
The utility model is the device of dismounting bearing, particularly a kind of bearing inner race drawbench.
Background technology:
When the dismounting bearing, generally be to adopt the method for bump that it is dismantled at present, this method inefficiency, labour intensity is big, and poor stability also damages bearing easily, and repair rate is low, increases the bearing consumption, increases production cost, deficiency in economic performance.
Summary of the invention:
The purpose of this utility model is a kind of bearing inner race drawbench of design, makes it in dismounting during bearing, saves time, laborsaving, convenient, fast.
The purpose of this utility model is achieved in that set screw nail, main body, bearing pin, screw rod, drawing bar composition, the drawing bar is connected on the crossbeam of main body by bearing pin, drawing bar, two symmetries of bearing pin are installed, the set screw nail is installed on perpendicular the propping up of main body, two symmetries of set screw nail are installed, the male thread of screw rod and the box thread on the main body screw, and drawing bar lower end has horizontal.
The beneficial effects of the utility model are: after horizontal of drawing bar lower end tangled bearing inner race, rotary screw just can disassemble bearing inner race, saved time during dismounting, laborsaving, workman sesame fatigue resistance is low, security is good, can not damage bearing, has remarkable economic efficiency and social benefit.
Description of drawings:
Accompanying drawing is the installation diagram of the utility model embodiment.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model is made up of set screw nail 1, main body 2, bearing pin 3, screw rod 4, drawing bar 5, drawing bar 5 is connected on the crossbeam of main body 2 by bearing pin 3, drawing bar 5 can rotate, and drawing bar 5,3 two symmetries of bearing pin are installed, and set screw nail 1 is installed on perpendicular the propping up of main body 2, set screw is followed closely 1 two symmetries and is installed, set screw nail 1 usefulness and the opening width of controlling drawing bar 5, the box thread on the male thread of screw rod 4 and the main body 2 screws, and drawing bar 5 lower ends have horizontal.
During the drawing bearing inner race, horizontal of drawing bar 5 lower ends tangle bearing inner race, rotary screw 4, and main body 2 is outwards walked, and makes bearing inner race produce axial force, thereby extracts bearing inner race.
