Description

Technical Field

[0001] The utility model relates to the technical field of gear boxes, in particular to an extruder gear box which is easy to install. Background Art

[0002] Extruders are common products in the field of plastic processing. Through the pressure and shear force generated by the rotation of the screw, the material can be fully plasticized and evenly mixed, and then formed through the die. In order to provide strong power to the screw, an extruder gearbox is required to slow down the rotational force and increase the torsional force to ensure the normal use of the extruder.

[0003] After searching, the Chinese patent application number 202320442172.9 discloses an extruder gearbox housing and an extruder gearbox, which relates to the field of gearboxes. The extruder gearbox housing includes a housing body, a sight hole cover and a reinforcing pin. A sight hole window is provided on the side of the housing body, and the sight hole cover is connected to the housing body and closes the sight hole window. The reinforcing pin is interference fit with both the housing body and the sight hole cover. The box body and the sight hole cover are connected as a whole by a reinforcing pin, and the reinforcing pin acts as a force transmission beam. When the box body is subjected to a large axial force, the axial force is transmitted to the sight hole cover through the reinforcing pin, and the sight hole cover and the box body are subjected to force balance. The force on the sight hole cover and the box body is basically equal. The side of the box body provided with the sight hole window is rigidly enhanced under the cooperation of the reinforcing pin and the sight hole cover. The sight hole window is not easy to deform and has a long service life. The sight hole cover and the box body are not easy to have axial displacement. The sight hole cover can better seal the sight hole window, and the risk of oil leakage from the sight hole window is small. The gearbox is safe and reliable during operation, and the operating cost is low.

[0004] The above patent still has the following deficiencies: (1) It is not easy to maintain. After long-term use, the internal gears of the device are severely worn, so it is necessary to regularly maintain and clean the inside of the device. However, since the upper and lower shells of the existing device are usually fixed with bolts, special tools or equipment are required to open the gear box, which increases the complexity and cost of maintenance. At the same time, it is difficult for engineers to quickly enter and check the internal conditions during regular inspections or when a fault occurs;

[0005] (2) It is not easy to install. After installation, the position and direction of the device need to be calibrated several times to ensure accurate docking with the extruder screw. The calibration process is cumbersome and the work efficiency is low.

[0006] Therefore, an extruder gearbox that is easy to install is urgently needed to solve the above problems. Utility Model Content
