Abstract
The utility model relates to an integrally-arranged bearing extractor for a transmission shaft. The integrally-arranged bearing extractor for the transmission shaft comprises an expander and a screw located in the expander and provided with a conic head portion; the tail portion of the screw is connected to the inner portion of a connecting rod in a threaded mode; a heavy punch sliding on the connecting rod is arranged on the connecting rod in a sleeved mode; a stopping block is fixed to the tail end of the connecting rod; through the inertia force of the heavy punch, the stopping block is struck, and detachment is achieved. According to the integrally-arranged bearing extractor for the transmission shaft, time and labor are saved, the shaft is protected against damage, and detachment can be conducted conveniently.
Description
Technical field
The utility model relates to a kind of power transmission shaft built-in bearing extracting tool, especially a kind of for dismantling the power transmission shaft built-in bearing extracting tool of bearing outer ring.
Background technology
In industrial production, during bearing damage in device or equipment, bearing need to be taken out to replacing, but due to the extruding force of bearing outer ring and axle medial surface, be difficult to directly take out.Be all generally to use iron hammer pointwise to knock bearing outer ring by artificial, could slowly bit by bit bearing outer ring be pounded out, so not only waste time and energy, but also be easy to damage axle.For this reason, insider has also made a lot of effort, for example China Patent No. is 201220089918.4 to disclose a kind of novel root filmatic bearing of press withdrawing device that rubs, it comprises bolt, expanding block and expander, one end of expander is the pyramidal structure of hollow, this pyramidal structure longitudinally on average has 4 otch, these 4 otch make this end form four valvular structures, the extension of each valvular structure is provided with ratchet, expander is arranged in the pyramidal structure of this hollow, bolt extend into expander inside through expander, and bolt is connected with expander internal whorl.While using this device, by bolt, by after expander and bearing compression, need to utilize top tool or draw tool that bearing is taken out, when taking out bearing, must also will be equipped with specially corresponding top tool or draw tool like this, using also cumbersome.
Utility model content
Purpose of design: avoid the weak point in background technology, designing does not a kind ofly need to be equipped with other instruments and just can directly take off bearing, easy to use, and the power transmission shaft built-in bearing extracting tool of protection axle.
Design: in order to realize above-mentioned purpose of design.1, by a screw rod being spirally connected with connecting rod, the tapering part of screw head matches with the flap head of expander, turns the screw on screw rod, and expander is squeezed on bearing outer ring, pulls connecting rod just can directly take off bearing outer ring.Active force is just dispersed on bearing outer ring like this, has effectively guaranteed the integrality of axle, avoids in bearing outer ring unloading process the damage to axle.2, the slidably weight being provided with on connecting rod, and the block of connecting rod tail end when pulling out bearing outer ring, slide weight on connecting rod, utilize the power that inertia produces to clash into block, directly bearing outer ring are pulled out.When taking out bearing outer ring, just do not need to use other instruments like this, save time and laborsaving.。
Technical scheme: a kind of power transmission shaft built-in bearing extracting tool, comprises the screw rod that expander and the head that is positioned at expander are taper; Screw rod tail is screwed onto in connecting rod; On connecting rod, be arranged with the weight sliding on connecting rod; Connecting rod tail end is fixed a block.
Preferably, described expander is T shape; The head of expander is circular arc, the body portion of expander and screw rod engagement; The head of expander is valvular structure; The conical nose of screw rod is positioned at the flap head of expander.
Preferably, on described screw rod, be fixed with screw; Screw is between expander and connecting rod.
Preferably, the leading portion of described connecting rod and screw rod junction are hollow, and back segment is solid.
Preferably, described tail of dog is fixed one and is held handle.
Preferably, the cross section of described weight is circular, and the area of section of weight is greater than the area of section of block.
Preferably, described weight outside is provided with a circle deep-slotted chip breaker.
The utility model is compared with background technology, and the one, active force is dispersed on whole bearing outer ring, protected the intact of axle, avoid the damage to axle in unloading process; The 2nd, utilize the inertia force of weight to unload bearing outer ring, greatly reduce operator's labour intensity, improved removal efficiency, saved the plenty of time; The 3rd, during dismounting, no longer need other aids, just can directly bearing outer ring be taken out, be more convenient for the carrying out of dismantlement work; The 4th, on weight, according to the hand shape of human body, have a circle deep-slotted chip breaker, facilitated the hand-held of operator, use convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the utility model power transmission shaft built-in bearing extracting tool;
Accompanying drawing 2 is the top view of accompanying drawing 1;
Wherein: 1, expander; 2, screw rod; 3, weight; 4, connecting rod; 5, screw; 6, block; 7, hold handle; 8, deep-slotted chip breaker.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Embodiment 1: with reference to accompanying drawing 1-2.A power transmission shaft built-in bearing extracting tool, comprises the screw rod 2 that expander 1 and the head that is positioned at expander 1 are taper; Screw rod 2 afterbodys are screwed onto in connecting rod 4; Expander 1 is T shape; The head of expander 1 is circular arc, the body portion of expander 1 and screw rod 2 engagements; The head of expander 1 is valvular structure; The conical nose of screw rod 2 is positioned at the flap head of expander 1; On screw rod 2, be fixed with screw 5; Screw 5 is between expander 1 and connecting rod 4; The leading portion of connecting rod 4 and screw rod 2 junctions are hollow, and back segment is solid; On connecting rod 4, be arranged with the weight 3 sliding on connecting rod 4; Connecting rod 4 tail ends are fixed a block 6; The tail end of block 6 is fixed one and is held handle 7; The cross section of weight 3 is circular, and the area of section of weight 3 is greater than the area of section of block 6; Weight 3 outsides, according to the design of human body hand shape, are provided with a circle deep-slotted chip breaker 8.When bearing damage, by turning of screw 5, the extruding force of the conical nose that loosens screw rod 2 to expander 1, expander 1 will shrink, expander 1 is stretched into damaged bearing outer ring, follow tighten the screws 5, allow 2 pairs of expanders of screw rod 1 produce extruding force, make expander 1 and damaged bearing outer ring in fastening combination, then pull weight 3, weight 3 slides on connecting rod 4, weight 3 is under the effect of inertia force, clash into block 6 and hold handle 7, damaged bearing outer ring each point being produced evenly to outwards pulling force, thereby bearing outer ring is taken out fast.
It is to be understood that: although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than the restriction to the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing, all falls in protection domain of the present utility model.
