Problems solved by technology

[0003] For 1.5 MW-class wind power bearings, two raceways with a diameter of 2 meters are processed, and the error of the center distance of the raceways must be controlled within 0.01 mm. The traditional single-raceway forming method is used to process one raceway before processing the

Example Embodiment

[0015] A preferred embodiment is given below to illustrate the present invention more clearly and completely in conjunction with the accompanying drawings.

[0016] The one-time forming and grinding method for double raceways of the present invention includes the following steps:

[0017] Step 1: Such as figure 1 As shown, the diamond roller 1 is mounted on a support 2, and the support 2 is fixed on the machine tool platform. The diamond roller is made of diamond grit and has the ability to polish the wheel. The center line of the diamond roller should be parallel to the center line of the main shaft of the grinding wheel. The bracket should have certain rigidity and be able to keep parallel with the grinding wheel spindle to avoid errors during correction. The diamond roller 1 and the bracket 2 constitute a grinding wheel corrector, and the grinding wheel corrector should have a rotating function, which can be rotated forwards and backwards as needed to meet the needs of grinding...

Abstract

The invention discloses a one-step form grinding method for double races, which includes the following steps: step 1: an emery wheel is mounted on a bracket, the emery wheel and the bracket are formed into a grinding wheel dresser, the bracket is fixed on a machine tool platform, and the central line of the emery wheel needs to be in parallel with the central line of the spindle of a grinding wheel; step 2: the emery wheel is rotated at high speed to dress the grinding wheel, so that the grinding wheel is formed into a shape required by grinding; and step 3: the dressed grinding wheel is used for grinding the inner and the outer races of a wind power bearing until the shapes of the inner and the outer races fully accord with the shape of the emery wheel and the requirement of a drawing. The one-step form grinding method for the double races increases the race-making precision.

Description

technical field [0001] The invention relates to a grinding method, in particular to a double raceway forming grinding method. Background technique [0002] Clean energy wind power has developed rapidly in recent years. With the expansion of the power generation level of wind turbines, the load-bearing requirements and machining accuracy requirements for the pitch and yaw bearings of the motor are getting higher and higher. In order to meet the load-bearing requirements, the bearing design is often At the same time, the design of double raceways is adopted and high requirements are put forward for the cooperation of the raceways. [0003] For 1.5 MW-class wind power bearings, two raceways with a diameter of 2 meters are processed, and the error of the center distance of the raceways must be controlled within 0.01 mm. The traditional single-raceway forming method is used to process one raceway before processing the other raceway. It is difficult to meet the requirements in te...
