The invention relates to a cycloid type reducer. The cycloid type reducer comprises a main body, an input shaft sleeve and two deceleration output units. Each deceleration output unit is separately provided with a cycloid wheel, an output element, a cross oldham and a plurality of rolling elements, and the cycloid wheels sleeve the input shaft sleeve. The cycloid wheels are provided with a plurality of cycloid wheel grooves, and a side groove wall of each the cycloid wheel groove is an oblique surface. A plurality of output element grooves are formed in one end surface of the output elements,the cross oldhams are provided with central ring parts and four binding parts bulging in a cross shape, and one side wall of each output element is an oblique surface. The two binding parts of the cross oldhams are placed in the cycloid wheel grooves of the cycloid wheels, the other two binding parts are placed in the output element grooves of the output elements, the rolling elements are separately placed between the oblique surfaces of the cycloid wheels and the oblique surfaces of the cross oldhams, and between the groove walls of the output element grooves and the side walls of the bindingparts of the cross oldhams. The effects that the assembly efficiency is good, transmission back gaps are reduced, an idle running phenomenon is avoided, the positioning accuracy is good, and collision noise is reduced are realized.

The powder bonding obstruction difficultly appears in the pulverizer disclosed in the invention in the use process.

The invention discloses a rotor-free through-flow measurement method for a steam turbine, and relates to a through-flow measurement method, in particular to a rotor-free through-flow measurement method for a steam turbine. The invention solves the problems in the prior art, such as complicated operation, low safety and high labor intensity. Specifically, the method comprises the following steps: doing preparation before measurement and making record cards, performing primary measurement of the axial dimension of a static part sleeve, performing primary measurement of the radial dimension of the static part sleeve, calculating the axial clearance of the static part sleeve and the radial clearance of the static part sleeve, dismounting each part sleeve and machining an eccentric pin and a support key, re-mounting a cylinder after completing the machining, and measuring the axial dimension and radial dimension of the static part sleeve again. The rotor-free through-flow measurement method is used for measuring the through-flow clearance of the static part sleeve of the steam turbine.
