[0002] At present, the usual design is to use a circular spacer ring to axially locate the tapered roller bearing. With this positioning method, since the spacer ring bears a large force and generates a large friction force, after installation and positioning The internal clearance of the tapered roller bearing cannot be adjusted by
Due to the uncontrollable errors generated during the manufacturing and installation process, the positioning accuracy of the tapered roller bearing cannot be guaranteed, which seriously reduces the service life of the tapered roller bearing

Embodiment Construction
[0016] In order to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, see Figure 1 to Figure 7 :
[0017] An adjustable tapered roller bearing axial positioning device implemented according to the present invention, it includes a bow shaft 2, the left and right shaft ends of the bow shaft 2 are provided with arcuate notches, and the arcuate notches are installed on the machine by fastening bolts. On the frame, the bow-shaped notch increases the contact area between the shaft and the frame, thereby increasing the connection strength. At the same time, in order to reduce vibration, a backing plate 3 is provided between the bow-shaped shaft 2 and the frame. The bow missing shaft 2 is provided with a shaft shoulder, where the tapered roller bearing 1 is installed. The shaft shoulder is used to locate the inner ring on one side of the tapere...

The invention relates to the field of machinery, in particular to an axial positioning device for an adjustable tapered roller bearing, which comprises a bow notch shaft. Both shaft ends of the bow notch shaft are provided with bow notches, a machine stand is installed at the bow notches, the bow notch shaft is provided with a shaft shoulder, a tapered roller bearing is installed at the shaft shoulder, and the inner ring of the tapered roller bearing is positioned. A lubricating oil injection pipe in which lubricating oil is injected is arranged inside the bow notch shaft. A transparent coverfor positioning the outer ring of the tapered roller bearing is installed on both sides of the tapered roller bearing, and the outer ring is equipped with a wheel or bearing pedestal. The bow notch shaft is provided with a distance ring, the head end of the distance ring is butted against the inner ring of the tapered roller bearing, the tail end of the distance ring is tightly butted against by a baffle plate at the shaft end of the bow notch shaft, and the baffle plate at the shaft end of the bow notch shaft is installed on the end face of the bow notch shaft through adjusting bolts. Through the adjusting bolts, the internal clearance of the tapered roller bearing can be changed in real time, the influence of equipment manufacture errors on bearing installation accuracy is eliminated, the service life of the tapered roller bearing is obviously prolonged; and the entire mechanism is simple, practical and easy to popularize.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to an adjustable tapered roller bearing axial positioning device. Background technique [0002] At present, the usual design is to use a circular spacer ring to axially locate the tapered roller bearing. With this positioning method, since the spacer ring bears a large force and generates a large friction force, after installation and positioning The internal clearance of tapered roller bearings cannot be adjusted. Due to the uncontrollable errors generated during the manufacturing and installation process, the positioning accuracy of the tapered roller bearing cannot be guaranteed, which seriously reduces the service life of the tapered roller bearing. Therefore, it is necessary to improve the existing tapered roller bearing positioning device, in order to reliably axially position the bearing, ensure the best clearance of the bearing, and improve the service life of the bearin...
