The technical scheme adopted by the utility model is as follows: a hydraulic motor fixing bolt is of a combined sectional bolt structure, and consists of a screw, a connecting rod and a screw rod, so that the tensile strength of the part is increased; the diameter of connecting rod is 40~60mm, length are 150~250mm, and the both ends of connecting rod are equipped with two internal thread holes respectively, and one end and screw connection, one end are connected with the screw rod, and the twin-roll main shaft is connected to the other end of screw rod, and the device is located hydraulic motor's inside center, has increased intensity. After the screw, the connecting rod and the screw are assembled in a combined way, the screw is in threaded connection with the double-roller base hole, and the screw presses the end cover part of the hydraulic motor on the double-roller main shaft to fix.
Further, the connecting rod is round steel. (the materials can be selected from tool steel with carbon content of 0.60 to 1.70 percent, 35 GrMoA)
Further, the pitch of the internal thread of the connecting rod is 2.0-3.0.
The steel types of the components of the utility model can comprise 50 steel, equal-high-strength carbon steel and stainless steel according to the use environment.
The diameter of the connecting rod of the combined bolt is 40-60 mm, the length of the connecting rod is 150-250 mm, the screw pitch of the connecting rod is 2.0-3.0, and the connecting rod can be adjusted according to equipment requirements.
The utility model has the beneficial effects that:
(1) The hydraulic motor is aligned to the shaft end through adjusting the screwing quantity of the screw, so that the fastening strength of the hydraulic motor at the shaft end is increased, the screw is not easy to loosen and break;
(2) Equipment accidents caused by loosening of the hydraulic motor are reduced or avoided;
(3) The maintenance frequency of the part is reduced.
The utility model is further described below with reference to the drawings and examples.
