Description

Technical Field

[0001] This utility model relates to the technical field of manufacturing special equipment for bearing torque inspection, and in particular to a torque measuring mechanism for high-pressure tapered bearings. Background Technology

[0002] The tapered bearing shaft torque inspection mechanism is a device used to inspect the rotation between the inner and outer rings of a tapered bearing, which helps to improve product quality and production efficiency.

[0003] However, in the existing technology, because the existing tapered roller bearings use manual semi-automatic torque measurement and inspection mechanisms, the measuring pressure is uneven and the inner tapered rollers are not rotated evenly during measurement. As a result, the measured torque data differs greatly from the actual bearing torque value, which seriously affects the product quality of the bearing in actual use. Utility Model Content

[0004] This invention addresses the aforementioned problems by providing a high-pressure tapered bearing torque measuring mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a high-pressure tapered bearing torque measuring mechanism, including a machine frame (1), a first flange bearing seat is embedded in the middle of the machine frame (1), and tapered bearing workpieces are fixed on both sides of the inner surface near the top edge of the bearing seat. A torque sensor (9) is provided at the upper end of the bearing seat. A stepper motor (10) is provided at the top of the machine frame. A ball bearing sleeve (7) is embedded in the middle of the machine frame near the bottom of the cylinder. The ball bearing sleeve guides the main shaft to ensure coaxiality when it rotates.

[0006] Preferably, a spline (17) is provided at the lower end of the spindle, and a servo lifting and pressurizing motor (16) is provided at the bottom of the equipment frame, and the servo lifting and pressurizing motor is connected to a bevel gear mechanism (15).

[0007] Preferably, the bevel gear mechanism output is provided with a ball screw lifting mechanism (14), and a pressure sensing system (11) is provided on the top of the ball screw lifting mechanism.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, when measuring torque, two different pressures are used, consisting of a first pressurization pressure and a second pressurization pressure. The pressurization and measurement lifting mechanism is driven by a servo motor, with a bevel gear mechanism for speed change and a ball screw lifting mechanism to output constant pressure. According to different pressures, the torque sensor can monitor the magnitude of the applied pressure in real time, thereby better solving the problem of inaccurate torque measurement and inspection of high-pressure round bearings, making it more accurate in use.
