Problems solved by technology
[0002] As we all know, in the field of gear transmission, at present, two sets of tooling are mostly used for the assembly and clearance measurement of bearings, especially in the assembly of cylindrical roller bearings of planetary gear components in wind power gearboxes. One set of tooling is used for assembly, and the other is used after assembly A set of tooling is used to measure the bearing clearance, which not only increases the cost of manufacturing the tooling, but also significantly lowers the production efficiency

Embodiment Construction
[0015] The bearing assembly measuring tool of the present invention includes a tool body 3 . One end of the tooling body 3 is the assembly end, the other end is the measuring end, the center is provided with an annular positioning cylinder 13, and the inner peripheral surface of the annular positioning cylinder 13 is provided with an annular support flange 12 with a flange width of 4 mm. An annular assembly step 10 is provided on the outer peripheral surface of the annular positioning cylinder 13 at the assembly end, and an annular assembly support surface 5 is provided on the annular assembly step 10 , and an annular groove 9 is formed between the annular assembly step 10 and the annular positioning cylinder 13 .
[0016] The outer cylindrical surface of the annular positioning cylinder 13 at the measuring end is provided with an annular measuring step 11, and the annular measuring step 11 is provided with an annular measuring support surface 6, which is 8 millimeters lower th...

The present invention relates to a bearing assembly and measurement tool which is mainly characterized in that one end of the tool body is an assembly end, and the other end is a measurement end; the centre of the tool is provided with an annular positioning cylinder; the inner circumference surface of the annular positioning cylinder is provided with an annular support flange; the outer circumference surface of the annular positioning cylinder at the assembly end is provided with an annular assembly step with a support surface; an annular groove is formed between the annular assembly step and the annular positioning cylinder; and the outer cylinder surface of the annular positioning cylinder at the measurement end is provided with an annular measurement step with a support surface. The bearing assembly and measurement tool is simple in structure, small in size, light in weight and convenient to operate and use; the assembly end surface of the tool is upward, a bearing base is arranged on the assembly support surface, and thus assembly can be finished; the measurement end surface of the tool is upward, and thus measurement of axial play of a bearing can be finished; the assembly and measurement are good in reliability; assembly and play measurement of the bearing can be finished with one set of tool, thereby reducing production cost, reducing tool switching time and improving production efficiency; and economic efficiency is good.
Description
technical field [0001] The invention relates to an assembly measurement tool, in particular to a bearing assembly measurement tool used for a cylindrical roller bearing of a planetary wheel assembly in a wind power gearbox. Background technique [0002] As we all know, in the field of gear transmission, at present, two sets of tooling are mostly used for the assembly and clearance measurement of bearings, especially in the assembly of cylindrical roller bearings of planetary gear components in wind power gearboxes. One set of tooling is used for assembly, and the other is used after assembly A set of tooling is used to measure the bearing clearance, which not only increases the cost of manufacturing the tooling, but also significantly lowers the production efficiency. In order to solve the above problems, reduce the manufacturing cost of the tooling, and save the time for changing the tooling, a tooling that can be used for both assembly and measurement is needed.
