Abstract
The utility model relates to a novel rotary transmission device, which belongs to the field of feeding and injection devices of a rubber or silica gel injection moulding machine. The novel rotary transmission device comprises an oil motor, a transmission shaft, a screw, a bearing seat and a deep groove ball bearing. The oil motor is assembled with the transmission shaft through an oil motor extension shaft. The transmission shaft is assembled with the screw and in the bearing seat. The novel rotary transmission device further comprises a thrust ball bearing and an angular contact ball bearing. The bearing seat is assembled with the transmission shaft in movable fit through the angular contact ball bearing, the thrust ball bearing and the deep groove ball bearing. The angular contact ball bearing, the thrust ball bearing and the deep groove ball bearing are arranged from the front to the back in sequence between the bearing seat and the transmission shaft. The novel rotary transmission device can ensure that the service life of the oil motor is not affected by other factors. The angular contact ball bearing has the function of automatic self-centralizing. The novel rotary transmission device has a long guidance length, and disturbance at the front end of the screw is reduced.

Background technology
The rubber of prior art or silicon gel injection forming machine pan feeding, material injection device, in its rotary actuator, only adopted a deep groove ball bearing, the rotary actuator of this structure has following shortcoming: 1, can not bear axial force, when spiro rod plasticizing and injection sizing material, suffered deboost acts directly on the oil motor projecting shaft, and oil motor is damaged easily; 2, can not automatic aligning, the center registration of screw rod and oil motor projecting shaft guarantees by part processing precision fully, make require high; 3, guiding length is short, and the screw front end disturbance is big.In order to prolong the service life of oil motor, make rubber or silicon gel injection forming machine pan feeding, material injection device energy automatic aligning, and make screw front end smooth working, people wish that urgently a kind of novel rotary actuator comes out.
Summary of the invention
Technical problem to be solved in the utility model is, overcome its oil motor of a kind of rotary actuator on the injection (mo(u)lding) machine of above-mentioned prior art damage easily, can not automatic aligning, guiding length is short, the screw front end disturbance is big defective, a kind of novel rotary actuator is provided, this novel rotary actuator can guarantee that the life-span of oil motor is not subjected to the influence of other factors, angular contact ball bearing has the automatic aligning function, and have than long guiding length, reduced the disturbance of screw front end, made the smooth working of screw front end energy.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel rotary actuator, comprise oil motor, power transmission shaft, screw rod, bearing block and deep groove ball bearing, oil motor is assembled together by oil motor projecting shaft and power transmission shaft, power transmission shaft and screw rod are assembled together, drive shaft cartridge fits in the bearing block, this rotary actuator also comprises a thrust ball bearing and an angular contact ball bearing, bearing block passes through angular contact ball bearing, thrust ball bearing and deep groove ball bearing and power transmission shaft are movingly that mode is assembled together, angular contact ball bearing, thrust ball bearing and deep groove ball bearing are arranged between bearing block and the power transmission shaft from front to back in regular turn.
In technique scheme, between angular contact ball bearing and thrust ball bearing, be provided with spacing, between thrust ball bearing and deep groove ball bearing, be provided with spacing.
This rotary actuator also comprises a protecgulum, and described protecgulum is solidly connected together by the front end position of screw and bearing block.
This rotary actuator also comprises a collar, and described collar is solidly connected together by the front end position of screw and power transmission shaft.
This rotary actuator also comprises a circlip for shaft, and described circlip for shaft is assemblied on the position, rear end of deep groove ball bearing.
This rotary actuator also comprises a rotary oil seal, and described rotary oil seal is assemblied on the front end position of angular contact ball bearing.
The beneficial effects of the utility model are: 1, owing to designed thrust ball bearing in the utility model, thrust ball bearing does not act on the oil motor reaction force of sizing material, and the life-span that has guaranteed oil motor is not subjected to the influence of other factors; 2, owing to designed angular contact ball bearing in the utility model, angular contact ball bearing has the automatic aligning function, can adjust automatically by bearing clearance for small processing, rigging error; 3, but the bearing of former and later two bearing radial forces (being angular contact ball bearing and thrust ball bearing) makes screw rod have long guiding length, has reduced the disturbance of screw front end, and screw front end can be worked reposefully.4, oil motor drives the power transmission shaft rotation, make screw rod have rotation plasticizing function, bearing (being angular contact ball bearing, thrust ball bearing and deep groove ball bearing) with a plurality of difference in functionalitys makes the screw rod smooth rotation, and has the bearing function of axial injection force and plasticizing opposite force.
