Example Embodiment

[0013] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0014] Such as figure 1 , 2 As shown, the present invention includes a positioning shaft 1 and a bearing 2. The positioning shaft 1 is provided with a rectangular groove 101, one end of the positioning shaft 1 is provided with a rib 103, and the rib 103 is an integral structure with the positioning shaft 1. A pressure plate 4 is provided at one end, and the pressure plate 4 is connected to the shaft end of the positioning shaft 1 through two positioning pin shafts 7. The inner ring of the bearing 2 is movably sleeved on the positioning shaft 1. The inner ring of the bearing 2 and the positioning shaft 1 have a clearance fit. The gap A between the inner ring of the bearing 2 and the positioning shaft 1 is between 0.5 and 1 mm. 2 There is an axial gap between the end surface of the inner ring and the pressure plate 4. The axial gap B betw...

Abstract

The invention relates to a dynamic tension acquisition unit of an automobile engine belt. The dynamic tension acquisition unit of the automobile engine belt is characterized by comprising a positioning shaft and a bearing, wherein a rectangular groove is formed in the positioning shaft, a retaining side is arranged at one end of the positioning shaft, and a press plate is arranged at the other end of the positioning shaft. The positioning shaft is movably sleeved with a bearing inner ring, and an axial gap is reserved between the end face of the bearing inner ring and the press plate. A pressure sensor is arranged in the rectangular groove, the sensor press plate is arranged between the pressure sensor and the bearing inner ring in an abutting mode, and the contact face between the sensor press plate and the bearing inner ring is an arc surface matched with the bearing inner ring. A belt wheel is embedded into a bearing outer ring through injection molding. When the dynamic tension acquisition unit is used, the belt wheel is attached to the belt, and the pressure sensor is located on the angular bisector of a belt contact. The dynamic tension acquisition unit is simple and compact in structure, low in manufacturing cost, convenient to operate and capable of detecting and acquiring the dynamic tension of the belt in real time, preventing belt breakage caused by too large dynamic tension or belt slippage caused by too small dynamic tension and providing data for belt wheel train optimization design.

Description

technical field [0001] The invention relates to a device for measuring belt tension, in particular to an acquisition unit for the dynamic tension of an automobile engine belt. Background technique [0002] For the tension detection of the transmission belt, generally only the detection instrument can be used to detect the belt tension in the static state, that is, only the static tension can be detected, such as the tension of the car engine belt, and the belt tension can only be detected in the static state, and use The automatic tensioner maintains the tension of the belt and absorbs vibration in the transmission state. However, in the transmission state of the belt, the dynamic tension of the belt cannot be detected and collected in real time, so it is difficult to prevent the belt from breaking due to excessive dynamic tension. The dynamic tension is too small and the belt slips. Contents of the invention [0003] In view of the above problems, the applicant has made ...
