Problems solved by technology

[0003] The present invention aims to solve the problem that the weight difference between the weight of the titanium alloy blades and the common alloy steel blades of the currently used coiled mushroom-shaped root blades makes the balance of the mushroom-shaped leaf root blades poor after sorting, and then As a result, it is impossible to assemble directly after sorting, and then a method for balancing the ring formation of fungal root blades is proposed, which can eliminate the weight difference between titanium alloy blades and ordinary alloy steel blades

specific Embodiment approach 1

[0018] Specific implementation mode one: combine figure 1 Describe this embodiment, the specific steps of the method described in this embodiment are as follows:

[0019] Step 1. Searching and weighing: the coiled fungus-shaped leaf root leaves include a titanium alloy blade 1 and multiple ordinary alloy steel blades 2. According to the shape of the blades, find out the titanium alloy blade 1 and ordinary alloy steel blades among the coiled leaves. alloy steel blade 2 and weigh the weight M of a single common alloy steel blade 2 t And the weight M of a single titanium alloy blade 1 2 , and calculate the weight difference between the two: M 1 -M 2 =ΔM;

[0020] Step 2. Calculating the weight loss: In order to meet the balance of the fungus-shaped leaf root and blade roulette, a region of the common alloy steel blade 2 is processed, and a specific part of the common alloy steel blade 2 is cut off to achieve a ring-shaped fungus Requirements for the balance of the blade root...

specific Embodiment approach 2

[0028] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the common alloy steel blade 2 in this embodiment is a 17-4PH alloy steel blade, a 12CrMo alloy steel blade or a 1Cr12Mo alloy steel blade. 17-4PH alloy steel, 12CrMo alloy and 1Cr12Mo alloy steel are all available alloy steels, and blades made of these alloy steels are suitable for the present invention. Other method steps are the same as those in the first embodiment.

Abstract

The invention discloses a balancing method for bacterial type looped blade roots and blades, and relates to a balancing method for the looped blade roots and blades. The balancing method aims to solve the problems that the existing used bacterial type looped blade roots and blades cannot be directly assembled after sequencing and are poor in balance after sequencing as the weights between a titanium alloy blade and normal alloy steel blades are different and a weight difference value exists. The balance method comprises the following steps: step 1, searching and weighing; step 2, calculating the reduced weight; step 3, determining the quantity of weight-reduced blade groups and the positions of central weight-reduced blades; step 4, further taking an integer to N2, firstly fixing the locations of the titanium alloy blade and the weight-reduced blades, and then marking the location serial numbers to the blades needing to be reduced by weight from the central weight-reduced blade to the blades on two sides; and step 5, performing gravitational torque test on all the blades. The balancing method can be used for balancing the bacterial type looped blade roots and blades.

Description

technical field [0001] The invention relates to a balancing method for forming circles of leaf roots and blades, in particular to a balancing method for forming circles of fungal-type leaf roots and leaves. Background technique [0002] In the existing ring-shaped fungi-shaped leaves, the end leaves are generally designed as titanium alloy leaves, while the other leaves are made of ordinary alloy steel leaves, which are in the shape of a typical oil mushroom, so they are called fungi-shaped leaves. , because the weight of titanium alloy blades is about 1 / 3 lighter than that of ordinary alloy steel blades, there is a weight difference between titanium alloy blades and ordinary alloy steel blades, which makes the balance of mushroom-shaped leaf root blades poor when they are arranged in circles. Can not meet the requirements of the balance, and finally can not be directly assembled after sorting. Contents of the invention [0003] The present invention aims to solve the pro...
