Abstract

The invention discloses a height measurement device used for measuring the height of to-be-measured shafting of a to-be-measured bearing. The height measurement device includes a workbench, a positioning tray, a rotating tray, a standard bar, a fixed cover with a flat top, a displacement measurement structure, a pressure drive structure, and a rotation drive structure. The height of a to-be-measured shafting can be measured accurately and conveniently through the displacement measurement structure and the pressure drive structure. The drive shaft of the pressure drive structure can apply an axial pressure to the to-be-measured shafting through the standard bar, and is connected with the input shaft of a to-be-measured bearing through the rotation drive structure so as to drive the to-be-measured shafting to rotate. The height measurement device of the invention meets various conditions of actual test. Moreover, the height of to-be-measured shafting with different center to-center distance can be measured by replacing the positioning tray and the rotating tray. The height measurement device is simple in structure and convenient to operate, and has obvious advantages in actual use.

Description

technical field [0001] The invention relates to the field of vehicle transmission measurement, in particular to a height measurement device. Background technique [0002] Tapered roller bearings are often used in automotive gearboxes, such as figure 1 As shown, there are input shaft, output shaft and differential gear on it, and the bottom is connected to the clutch housing, that is, the bottom of the tapered roller bearing is connected to the connecting surface of the clutch housing, and each shafting is provided with a corresponding bearing , since the inner and outer rings of tapered roller bearings are in a separated state, their height needs to be measured during use, that is, the height of each shaft system is measured, specifically the height of the outer end surface of the bearing of each shaft system from the connecting surface of the clutch housing. measurement, such as figure 1 Shown in H, and select the appropriate gasket to preload the shafting according to th...
