Abstract
The utility model relates to a double brake planet speed adjusting device, relating to the technical field of mechanical tools, provided with a pressure bearing disc and a pressure bearing barrel. The pressure bearing barrel is connected with outer friction plates; inner friction plates are arranged among the outer friction plates; the inner friction plates are respectively connected with an outer gear ring and a planet carrier. In the states of high speed and low speed, the inner and the outer friction plates respectively brake the outer gear ring and the planet carrier. Therefore, rotating parts are reduced; structure is simplified, so that operating force and support stiffness are reduced.
Description
The utility model relates to the facility technical field, belongs to mining Transport Machinery and building whim tool.
At present, mining different capacity JD series car hauler has only mono-haulage speed and tractive force, building whim has JJMW, JW is series and JIK at a slow speed, JK is series fast, above-mentioned winch all belongs to single function, the patent No. is 85203977.8 planet differential speed change mine winch, at first realized specific function with the speed change variable load, but its operational brake of implementing speed changing function is in extra-organismal belt brake system, number of patent application is 88210575.1 friction plate clutch planet differential speed-changeable winch, adopt the friction plate clutch brake mode, the function that makes mining JD series winch and building whim that the variable load speed change all be arranged, the difunctional series of products of exploitation unit, but the berth-changing strength of this kind friction plate clutch planet differential speed-changeable winch is big, the requirement of complete machine rigidity out of reach, so that can't carry out commercial production and practical application.
The purpose of this utility model is at above-mentioned situation, it is number of patent application the friction plate clutch brake mode of 88210575.1 friction plate clutch planet differential speed-changeable winch, change two brake types into, thereby minimizing rotatable parts, simplified structure, improve transmission and power path, operating effort, support stiffness are reduced greatly, reach the industrialness working condition.
The utility model includes the bearing disc and the pressure-bearing tube that are fixed on the motor cabinet, be plain bearing between pressure-bearing tube and the cylinder, screw collar and threaded body are arranged in the pressure-bearing tube, to realize speed control, screw collar and threaded body are threaded, be connected with gear-shift lever on the screw collar, be connected with outside friction disc on the pressure-bearing tube, be the internal friction sheet between the outside friction disc, the internal friction sheet is connected on external toothing and the pinion carrier, is placed with bearing cap shim between motor cabinet and pressure-bearing tube, so that can adjust the gap of friction lining easily, outside friction disc is formed by 7, and the internal friction sheet is formed by 5, is connected with brake gear in the cylinder outside.
Pressure-bearing tube of the present utility model separates extraneous power and berth-changing strength, and the gear shift axial force is born by the pressure-bearing tube, alleviates support stiffness, and berth-changing strength is reduced greatly.Screw thread amplification by threaded body, screw collar, make the power that manually acts on the gear-change operation handle convert the positive pressure of internal friction sheet and outside friction disc to, brake pinion carrier and internally toothed annulus respectively, to realize low, the high-grade speed of winch, thereby rotatable parts have been reduced, simplify the structure, support stiffness is reduced greatly, reached industrialness production and practical condition.
Accompanying drawing shows the embodiment of this pair of brake type planetary speed regulating device, wherein:
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the assembly drowing of embodiment.
In the present embodiment, this pair of brake type planetary speed regulating device, comprise the bearing disc (3) and the pressure-bearing tube (7) that are fixed on the motor cabinet (1), be plain bearing (6) between pressure-bearing tube (7) and the cylinder (5), screw collar (8) and threaded body (9) are arranged in the pressure-bearing tube (7), screw collar (8) and threaded body (9) are threaded, be connected with gear-shift lever (4) on the screw collar (8), be connected with outside friction disc (10) on the pressure-bearing tube (7), between the outside friction disc (10) internal friction sheet (11), internal friction sheet (11) is connected on external toothing (12) and the pinion carrier (13), is placed with bearing cap shim (2) between motor cabinet (1) and pressure-bearing tube (7).Be connected with brake gear (14) in the cylinder outside.
In the embodiment of this pair of brake type planetary speed regulating device, when needs cylinder (5) microrunning, handle gear-shift lever (4), make screw collar (8) execute commentaries on classics, threaded body (9) moves to left, the internal friction sheet (11) that be connected on the pinion carrier (13) this moment combines with outside friction disc (10), thereby braking pinion carrier (13) realizes cylinder (5) microrunning; When needs cylinder (5) fast turn-around, reversible control gear-shift lever (4), make screw collar (8) retrograde rotation, threaded body (9) moves to right, and the internal friction sheet (11) that be connected on the internally toothed annulus (12) this moment combines with outside friction disc (10), thereby braking internally toothed annulus (12), realize cylinder (5) fast turn-around, this pair of brake type planetary speed regulating device is when at a slow speed with fast slewing, do not need to stop, under former operative condition, realize throw-over.
Claims (2)
1, a kind of pair of brake type planetary speed regulating device, it is characterized in that having the bearing disc (3) and the pressure-bearing tube (7) that are fixed on the motor cabinet (1), be plain bearing (6) between the outside of pressure-bearing tube (7) and the cylinder (5), screw collar (8) and threaded body (9) are arranged in the pressure-bearing tube (7), screw collar (8) and threaded body (9) are threaded, be connected with gear-shift lever (4) on the screw collar (8), be connected with outside friction disc (10) on the pressure-bearing tube (7), between the outside friction disc (10) internal friction sheet (11), internal friction sheet (11) is connected on external toothing (12) and the pinion carrier (13), is placed with bearing cap shim (2) between motor cabinet (1) and pressure-bearing tube (7).
