The utility model discloses an integral type hydraulic motor for a hydraulic air conditioner, and belongs to the technical field of air conditioners of engineering trucks. The integral type hydraulic motor consists of a shaft coupling and an integral motor, wherein the integral motor is an integrally combined piece formed by a main body part, and a front end cover part, a back end cover part and a fastening piece which are assembled with the main body part; the front end part is an integral piece formed by a front end cover structural piece, and a fixed support structure and a lug boss support structure which are assembled with the front end cover structural piece; and a spindle mounting hole on the front end cover structural piece is coaxial with a compressor spindle mounting hole formed on a front end vertical plate of the fixed support structure. The integral type hydraulic motor has the advantages that the coaxiality of the coaxial holes and the assembly precision are convenient to control in the processing and assembly process, and the problems that the structure of a connection and transmission part of the hydraulic motor and an air conditioner compressor is complex, a large number of independent parts are arranged, the assembly cumulative error is large, the assembly precision is inconvenient to control, the uniformity of operation sound is poor, the assembly efficiency is low, the transmission precision and the reliability are inconvenient to control, the maintenance is inconvenient, are solved.
