Description
Technical Field
The utility model relates to a gear box centering device.
Background
The gear box is a common industrial device and is widely applied to the fields of transmission, aviation, navigation, metallurgy, fluid transportation, petroleum production and the like. Misalignment of the gearbox refers to the offset or skew of the gearbox rotational axis from the rotational axis of the drive motor. Misalignment of the gearbox rotational axis is a common cause of gearbox failure. Misalignment can cause abnormal mechanical vibration of the gearbox, aggravate wear of bearings of the gearbox and deflection deformation of a shaft, and cause great damage to smooth operation of the gearbox. Misalignment of the gearbox should be minimized. A dial indicator and a multimeter rod are usually adopted in the gear box pair, but when the gear box shaft is an internal spline shaft, the direct measurement of the dial indicator and the multimeter rod cannot be adopted due to structural reasons.
Disclosure of Invention
An object of the utility model is to provide an inflation formula connection centering device that is used for internal spline centering of solving transmission gear box internal spline shaft centering problem.
The purpose of the utility model is realized like this:
the utility model relates to an inflation formula connection centering device for internal spline centering, characterized by: including steel pipe, pull rod, inflation taper sleeve, gearbox shaft internal spline, the one end of pull rod is located the steel pipe, the other end of pull rod is located the steel pipe outside and connects the multimeter bar, mounting nut on the pull rod, the nut pastes in the tip of steel pipe, the inflation taper sleeve is located gearbox shaft internal spline, the inflation taper sleeve overlaps the tip that is located the steel pipe in the pull rod and in the steel pipe laminating, behind the swivel nut, the steel pipe is along pull rod extrusion inflation taper sleeve, the installation percentage table on the multimeter bar.
The utility model discloses can also include:
1. the expansion taper sleeve is matched with an internal spline of the gear box shaft and is connected together through friction force.
The utility model has the advantages that: the utility model has the characteristics of simple structure, test efficiency are high, the operating mode is many, strong operability and practicality are strong etc.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be described in more detail below by way of example with reference to the accompanying drawings:
combine fig. 1, the utility model discloses constitute by expansion taper sleeve 1, pull rod 2, steel pipe 3, nut 4, universal meter pole 5, percentage table 6, gearbox axle internal spline 7, impress expansion taper sleeve 1 in gearbox axle internal spline 7 through nut 4, steel pipe 3, 2 one sides of pull rod are connected percentage table 6 and universal meter pole 5.
The nut 4 is rotated, and the expansion taper sleeve 1 is extruded along the conical surface of the pull rod 2 through the steel pipe 3. The expansion taper sleeve 1 deforms along the radial direction and is firmly connected with the internal spline 7 of the gear box shaft by friction force. At this time, the dial indicator 6 and the multimeter bar 5 can be connected to one side of the pull rod 2 to perform gear box shaft centering. According to the method, the expansion taper sleeve 1 can be replaced to match with the gear box shaft internal spline 7 with different sizes for centering.
