Embodiment Construction
[0027] see figure 1 , the main tooth assembly involved in this embodiment includes a lock nut 1, a main tooth flange 2, an oil seal 3, a bearing housing 4, a driving gear 5, an upper bearing 6, an adjusting washer 7, a lower bearing 8 and a spacer 9.
[0028] see figure 2 , the friction torque detection mechanism of the main tooth assembly bearing seat is driven by a servo motor 20, and a reducer 19 and a dynamic torque sensor 17 are arranged between the drive source and the output mechanism. The strain shaft of the dynamic torque sensor 17 protrudes from both ends, The end strain shafts are respectively connected with the output end of the reducer 19 and the shaft connecting the synchronous pulley I16 through the flat key, and a synchronous belt for speed and torque transmission is set between the synchronous pulley I16 and the synchronous pulley II11. A dial 27 is arranged below the pulley II11, and a flexible shift fork 21 extending into the bolt hole of the bearing seat...

The invention provides a measuring mechanism for the pressure assembling of the main reducers of automobiles, which comprises a friction torque tester for the bearing seat of a main gear assembly and an upper bearing inner ring pressure-assembling mechanism, and is characterized in that the bearing seat friction torque tester takes a servo motor as a drive. The friction torque of a main gear assembly to be measured is transmitted in sequence through the rotation of the bearing seat to a drive fork, a drive disc, a synchronous belt wheel II, a synchronous belt wheel I and a torque sensor, thereby the torque necessary for rotating the bearing seat of the main gear is transmitted to a rotary torque sensor, and a frequency signal is formed; by data acquisition treatment, real-time torque of the bearing seat can be obtained. The invention is for detecting the friction torque of the main gear assembly while pressure assembling the inner ring of the upper bearing of the main gear assembly of the main reducer of an automobile, and realizes automatic measurement of small torque. Measuring the friction torque of the main gear assembly can check whether the selection of the shim in previous station is correct, and effectively improve the quality and efficiency in assembling the main reducers of drive axles of automobiles.
Description
Technical field: [0001] The invention relates to the press-fitting of the inner ring of the tapered roller bearing on the main reducer of the automobile drive axle and the measurement of the friction torque of the main tooth assembly, so as to realize the automatic measurement of small torque. Background technique: [0002] The car drive axle is an important large assembly of the car. It is located at the end of the car drive train. Its basic function is to increase the torque transmitted from the drive shaft or directly from the transmission, distribute it to the left and right drive wheels, and make it The left and right driving wheels have the differential function required by the driving kinematics of the car; at the same time, they bear the full sprung load of the car and the plumb force, longitudinal force, and lateral force given by the ground through the wheel, frame or load-bearing body through the suspension. Forces and their moments, as well as shock loads. In a ...
