Abstract
Provided is a rotation power head of a coaxial spiral movable drive drilling rig. A hollow output shaft is installed on a bearing A and a bearing C of a machine frame, an input shaft is supported on a bearing B and a bearing D, a support is fixed on the machine frame, a motor is fixed on the support and connected with the input shaft, the machine frame is provided with a steel ball loop hole, and a group of steel balls are installed on the machine frame. The machine frame and the input shaft are provided with spiral grooves, axial guide grooves are evenly distributed on an output 1, and accordingly a spiral steel ball speed reducer is formed. An air chamber is provided with an air inlet and fixed on the machine frame through a flange, a seal A and a seal B are matched with the air chamber and the output shaft, a radial hole arranged on the output shaft is communicated with the air chamber, and the output shaft is provided with internal threaded holes. The rotation power head of the coaxial spiral movable drive drilling rig has advantages that in a coaxial spiral movable drive device, moving pieces such as an input shaft of a speed reducer are self-balancing, the transmission ratio is large, random selection can be performed, and the drilling rig rotation power head applying the device is a rock drilling machine which is convenient to disassemble, large in contact ratio, high in bearing capacity, large in transmission torque, small in radial dimension and suitable for heavy load.
Description
Technical field
The utility model relates to a kind of rock drilling machinery equipment, is a kind of coaxial spiral activity transmission rig rotary motive power head specifically.
Background technology
Various rigs are widely used in the engineering explosion hole drill cutter operations such as metallurgy, railway, mine, building materials, highway.Rig rotary motive power head is one of critical component of rig, and its speed change gear requires in light weight, and barycenter is low; High-speed cutting is bored the rotary motive power head and is required the dynamic equilibrium characteristic good, and gear range is big, but existing universal speed reducer radial dimension is big; Do not satisfy instructions for use; Movable teeth reducer is a tooth difference eccentric wheel structure, and the dynamic equilibrium characteristic is poor, and the rotary motive power head needs specialized designs.
The utility model content
In order to overcome the deficiency that above-mentioned technology exists, the utility model technical problem to be solved provides a kind of easy accessibility, and radial dimension is little, transfer torque is big, the coaxial spiral activity transmission rig rotary motive power head of suitable heavy load.
The technical scheme of the utility model is: a kind of coaxial spiral activity transmission rig rotary motive power head, comprise output shaft, air chamber, flange, bearing A, bearing B, steel ball, frame, power shaft, bearing C, bearings D, support, motor, sealing A, sealing B, and it is characterized in that: on the bearing A of frame, the bearing C hollow output shaft is housed; Power shaft is bearing on bearing B, the bearings D, and support is fixed on the frame, and motor is fixed on the support; And connect with power shaft, frame has hole, steel ball loop, and one group of steel ball is housed; Frame and power shaft all have helicla flute, and output 1 is uniformly distributed with axial channel, thereby constitute spiral steel ball deceleration device; Air inlet is arranged on the air chamber, and air chamber is fixed on the frame through flange, and sealing A and sealing B cooperate with air chamber, output shaft; Radial hole communicates with air chamber on the output shaft, and internal thread hole is arranged on the output shaft.
Said air chamber can also be made an integral body with flange and directly be fixed on the frame.
The utility model has the advantages that: the movable transmission device of coaxial spiral, movement parts such as the power shaft of speed changer are self-balancing, and gearratio is big; Can choose arbitrarily; Use the rig rotary motive power head of this device, easy accessibility, registration is big; Supporting capacity is high, and transfer torque is big, radial dimension is little, the rock drilling machinery of suitable heavy load.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Combine accompanying drawing at present, the technology contents of the utility model is described further.
As shown in Figure 1, on the bearing A4 of frame 7, the bearing C9 hollow output shaft 1 is housed, power shaft 8 is bearing on bearing B5, the bearings D 10, and support 11 is fixed on the frame 7; Motor 12 is fixed on the support 11, and connects with power shaft 8, and frame 7 has hole, steel ball loop; One group of steel ball 6 is housed, and frame 7 all has helicla flute with power shaft 8, and output shaft 1 is uniformly distributed with axial channel; Thereby constitute spiral steel ball deceleration device, on the air chamber 2 air inlet is arranged, air chamber 2 is fixed on the frame 7 through flange 3; Sealing A13 and sealing B14 cooperate with air chamber 2, output shaft 1, and radial hole communicates with air chamber 2 on the output shaft 1, on the output shaft 1 internal thread hole is arranged.
Wherein, air chamber 2 can also be made an integral body with flange 3 and directly is fixed on the frame 7.
