Embodiment Construction
[0016] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.
[0017] figure 1 The straight-toothed bevel gear tooth thickness inspection tool shown is composed of a base 1, a washer 2, a dial indicator 3, a positioning seat 4 and a screw 5. The base 1 is the basic part of the inspection tool. The base 1 in the shape of ⊥ uses a horizontal bottom plate as a supporting surface, and a vertical mandrel 1.1 is arranged in the center of the bottom plate. The diameter of the mandrel 1.1 is the same as that of the straight bevel gear 6 to be tested. The hole diameters are equal, and the matching accuracy is equal to the design accuracy of the straight bevel gear 6 to be tested. The positioning seat 4 fitted with the mandrel 1.1 is determined by the washer 2 at the installation height, and the specific height value is suitable for adult operation. The positioning seat 4 is the main component of the inspe...

The invention discloses a tooth thickness gauge for a straight bevel gear.The tooth thickness gauge is composed of a base, a gasket, dial indicators, a positioning base and screws.A mandrel is arranged on the base, the height of the positioning base sleeving the mandrel is determined by the gasket, an inner shoulder is arranged in a downward groove of the positioning base, and an inner orifice, lower than the outer edge, of the inner shoulder is machined into an outer convex semicircular corner.A through hole in the positioning base is in clearance fit with the mandrel on the base, an outer circular cone with the size and direction identical to those of the pitch angle is manufactured on the outline of the positioning base according to the pitch angle of the straight bevel gear to be detected, at least one vertical through hole for inserting one dial indicator is formed on the portions, where the nominal big end tooth thickness position and the middle point tooth thickness position are located, of the circumference, and the screws screwed in the radial direction are arranged in each through hole for locking the corresponding dial indicator.The tooth thickness gauge is high in detection precision and efficiency, particularly suitable for detecting finished straight bevel gear products in batches and capable of precisely detecting tooth thickness of electrode gears and precise forged gear blanks, and the requirement for detection conditions is low.
Description
technical field [0001] The invention relates to a checking tool for measuring the relative dimensions of mechanical parts. Specifically, the invention relates to a checking tool for measuring the tooth thickness of a gear, especially a checking tool for measuring the tooth thickness of a straight bevel gear. Background technique [0002] Conical or umbrella-shaped straight bevel gears, commonly known as bevel gears. The tooth structure of straight bevel gears is characterized by unequal modulus along the tooth length direction, that is, the modulus from the large end to the small end of the gear tooth decreases from large to small, and the tooth thickness decreases accordingly as the modulus decreases. In order to accurately define the modulus of straight bevel gears, the big-end modulus and mid-point modulus are uniformly designated in the industry as assessment items, so there are corresponding big-end tooth thicknesses and mid-point tooth thicknesses. The measurement of ...
