Abstract
The utility model relates to a dismounting device for an output shaft oil seal of an automobile transmission, which consists of 4 dismounting arms, a disc body, a cover plate and a rotating disc; the handle on the rotating disk is rotated, the tooth grooves on the short arms on the disassembling arms are driven by the spiral grooves on the lower end face of the rotating disk, and then the disassembling arms are driven to perform outward expansion and inward contraction movement in the T-shaped grooves of the disk body, so that the diameter size of an output shaft oil seal is met. The smooth curved surface at the front end of the long arm of the dismounting arm is used for pressing the output shaft oil seal out of the transmission shell. The utility model is used for dismounting device of automotive transmission output shaft oil blanket adopts the principle of helicla flute drive rack motion, and spare part mechanism is ripe, and processing and maintenance cost are lower, can freely adjust the distance of dismantling between the arm, adapt to the oil blanket of different diameters size, and the terminal surface is smooth curved surface before dismantling the long arm in the arm, and 4 dismantle the arm and can make the even atress of oil blanket, dismantle the in-process and reduce the oil blanket and warp the risk, improve and dismantle efficiency, reduce the dismantlement cost.
Description
Technical Field
The utility model belongs to the technical field of the auto parts, concretely relates to a dismounting device for automotive transmission output shaft oil blanket.
Background
The oil seal of the output shaft of the transmission is an important part for preventing oil leakage of the transmission, is in interference fit with a transmission shell, and mainly comprises rubber. After the oil seal is deformed, the sealing effect is deteriorated, the oil leakage phenomenon can occur, and the service life of the transmission is shortened. At present, the oil seal of the output shaft of the domestic transmission is mostly disassembled and assembled at one time, the disassembled and assembled oil seal can be integrally deformed and cannot be continuously used, and a special device is not used for protectively disassembling the oil seal of the output shaft of the transmission.
Disclosure of Invention
The utility model discloses just aim at providing a dismounting device for automotive transmission output shaft oil blanket to above-mentioned prior art not enough, the device can dismantle the arm position as required adjustment and adapt to oil blanket diameter size, dismantles the arm and can make the even atress of oil blanket, dismantles the in-process and reduces the oil blanket and warp the risk, improves and dismantles efficiency, reduces and dismantles the cost.
The utility model aims at realizing through the following technical scheme:
the utility model provides a dismounting device for automotive transmission output shaft oil blanket which characterized in that: the device is composed of 4 disassembly arms 1, a disc body 2, a cover plate 3 and a rotating disc 5;
the disassembly arm 1 is L type and comprises a long arm and a short arm, the front end of the long arm of the disassembly arm 1 is a smooth curved surface, a tooth groove is processed on the short arm on the disassembly arm 1, a spiral groove is processed on the lower end face of the rotary disk 5, after the disassembly arm 1 is installed in the T-shaped groove of the disk body 2, the rotary disk 5 is placed into the disk body 2, and the cover plate 3 is connected onto the disk body 2 through bolts 4.
The handle on the rotating disk 5 is rotated, the tooth grooves on the short arms on the disassembling arms 1 are driven by the spiral grooves on the lower end face of the rotating disk 5, and then the disassembling arms 1 are driven to perform outward expansion and inward contraction movement in the T-shaped grooves of the disk body 2, so that the diameter size of the output shaft oil seal 7 is met. The smooth curved surface of the long arm front end of the dismounting arm 1 is used for pressing the output shaft oil seal 7 out of the transmission housing 6.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model is used for dismounting device of automotive transmission output shaft oil blanket adopts the principle of helicla flute drive rack motion, and spare part mechanism is ripe, and processing and maintenance cost are lower, can freely adjust the distance of dismantling between the arm, adapt to the oil blanket of different diameters size, and the terminal surface is smooth curved surface before dismantling the long arm in the arm, and 4 dismantle the arm and can make the even atress of oil blanket, dismantle the in-process and reduce the oil blanket and warp the risk, improve and dismantle efficiency, reduce the dismantlement cost.
