Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention. As used herein, the singular forms "a", "an", and/or "the" are intended to include the plural forms as well, unless the invention expressly state otherwise, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof;
just as the background art introduces, there is the problem that needs violence to demolish the spline housing among the prior art, in order to solve above technical problem, the utility model provides a tipper rotor spline housing extracting tool.
The utility model discloses an among the typical embodiment, refer to fig. 1 and show, a tipper rotor spline housing extracting tool, including two halves butt joint cover 1, butt joint cover 1 assembles annular cover in the motor shaft hoop, and the butt joint cover tip sets up first step, and one side of first step is with 7 one end blocks of spline housing, and the fixed cover of cover income formula is in butt joint cover's hoop, and drawing mechanism offsets with the motor shaft, and drawing mechanism 4's output is with the fixed cover contact of cover income formula to the output power that will draw mechanism acts on butt joint cover through the fixed cover of cover income formula, thereby acts on the spline housing through the butt joint cover, realizes the dismantlement of butt joint spline housing.
It should be explained that the spline housing is mounted in the circumferential direction of the motor shaft.
Considering the position for detaching the spline sleeve, the complete sleeve cannot be installed, and in order to facilitate installation, in this embodiment, the docking sleeve 1 comprises two halves, the two halves of the docking sleeve have the same inner diameter, and the same width and radian; in other examples, the radians of the two half butting sleeves can be arranged differently as long as the two half butting sleeves can be assembled in the annular direction of the motor and can transmit force to the element changing sleeve.
Understandably, the inner side and the outer side of the butt joint sleeve 1 are provided with first steps 5, the inner side of the butt joint sleeve is clamped into the outer side of the spline sleeve, and the first steps outside the butt joint sleeve are used for being matched with the sleeved fixing sleeve, so that the clamping of the sleeved fixing sleeve can be effectively guaranteed.
In this embodiment, specifically, drawing mechanism is current hydraulic pressure chest expander, and hydraulic pressure chest expander has the action bars, and hydraulic pressure chest expander sets up a plurality of stationary dogs, and is 3 under the normal conditions, guarantees the atress equilibrium, has significantly reduced the input of manpower and maintenance resource from this, uses extracting tool only need one to two people assist mounting tool, operates hydraulic pressure chest expander, just can accomplish this type of maintenance work.
Correspondingly, the fixed claw of hydraulic pressure chest expander acts on the fixed cover outside of pullover, and the fixed claw of hydraulic pressure chest expander acts on fixed cover 2 of pullover like this, and then transmits the effort to the butt joint cover to realize the dismantlement of spline housing.
In this embodiment, the fixed cover 2 of the inserted type is an integral structure, and is sleeved on the outer ring of the docking sleeve, and the docking sleeve is sleeved on the ring direction of the motor shaft, and the docking sleeve 1 is contacted with the motor shaft, and because of the arrangement of the first step at the inner side of the docking sleeve, one end of the docking sleeve is clamped on the spline housing, and the inner diameter of the end of the docking sleeve is smaller than the outer diameter of the spline housing.
Specifically, the longitudinal section of the butting sleeve 1 is in two transverse T shapes, the inner side shape of the sleeved fixing sleeve 2 is fitted with the outer side shape of the butting sleeve, and the width of the sleeved fixing sleeve 2 is the same as that of the butting sleeve 1.
The fixed cover 2 rings of cover income formula are gone to the outside and are set up second step 6, and the fixed cover 2 one side external diameter of cover income formula is greater than the opposite side external diameter like this, and the fixed cover 2 rings of cover income formula are only two kinds of external diameter sizes, and the one end that the external diameter is big is close to the spline housing setting for the stationary dog of hydraulic pressure chest expander acts on second step 6 (the less one side of the fixed cover external diameter of cover income formula promptly) department, and the claw end inboard of stationary dog can stably grab and hold the great one side of overcoat external diameter like this, thereby the hydraulic pressure chest expander of being convenient for sends out power.
When the motor is installed, the butt-joint sleeve is directly used in the circumferential direction of a motor shaft, and then the sleeved fixing sleeve 2 is fixed on the butt-joint sleeve.
