Abstract
The utility model relates to a lifting mechanism with an integrated support, which comprises the integrated support and a motor, a speed reductor and a winding drum which are fixed on the integrated support. The motor is connected with an input spline shaft; the input spline shaft is connected with a primary sun gear; the primary sun gear is meshed with a primary planet gear; the primary planet gear is meshed with a primary annular gear and is connected with a secondary sun gear by a primary planet carrier; the secondary sun gear is meshed with a secondary planet gear; the secondary planet gear is meshed with a secondary annular gear and is connected with a secondary planet carrier; the secondary planet carrier is connected with an output shaft; and the output shaft is connected with the winding drum. A caliper disc brake is arranged on the winding drum and takes an effect of rapidly braking. According to the utility model, due to the adoption of the integrated support, the coaxiality of the output shaft and the bracket is improved, so that not only are the transmission stability and the service life of the complete machine improved and the driving torque is larger, but also the lifting mechanism is convenient to install and overhaul and the sealing performance is improved.
Description
Technical field
The utility model relates to a kind of parts that hoist, and particularly is suitable for a kind of lifting mechanism of crawler crane.
Background technology
Lifting mechanism generally comprises motor, reductor, reel, power-transfer clutch, drg, steel rope.Requiring of at present domestic rated load to crawler crane, wheel crane is increasingly high, thereby requires the output torque of lifting mechanism reductor increasing, and the complete machine size of corresponding lifting mechanism is increasing, causes the installation difficulty of lifting mechanism increasingly high.And, cause reduce greatly the service life of reductor because the output main shaft concentricity of mounting bracket on the main frame and reductor is not high.So, on the basis that guarantees the lifting mechanism work efficiency, reduce installation, the maintenance difficulty of complete machine, be urgent problem the service life of improving complete machine.
The utility model content
To prior art problems, the utility model provides a kind of lifting mechanism of integral type bearing, and this lifting mechanism has improved the transmission stability and the service life of complete machine, the convenient installation and maintenance.
The technical scheme of the utility model is: a kind of lifting mechanism of integral type bearing comprises the integral type bearing and is fixed on motor, reductor and the reel on the integral type bearing that said motor is connected with the input castellated shaft; The input castellated shaft is connected with first order sun wheel, first order sun wheel and the engagement of first order satellite gear, first order satellite gear and the engagement of first order internally toothed annulus; And be connected with second stage sun wheel through first order pinion carrier; Second stage sun wheel and the engagement of second stage satellite gear, second stage satellite gear and second stage internally toothed annulus mesh, and are connected with second stage pinion carrier; Second stage pinion carrier is connected with output shaft, and output shaft is connected with reel.
Preferably, said reel is provided with caliper disk brake, plays quick braking action.
The beneficial effect of the utility model is:
(1) the utility model adopts the integral type bearing, has increased the right alignment of output shaft and support, the transmission stability and the service life of both having improved complete machine makes driving torque bigger, and convenient again the installation and maintenance increased leak tightness.
(2) the utility model is installed caliper disk brake on bearing, plays the auxiliary effect of brake fast, increases conservative factor, improves the service life and the work efficiency of complete machine.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
A kind of lifting mechanism of integral type bearing comprises integral type bearing 2 and is fixed on motor 1, reductor and the reel 3 on the integral type bearing 2 that said motor 1 is connected with input castellated shaft 4; Input castellated shaft 4 is connected with first order sun wheel 5, first order sun wheel 5 and 6 engagements of first order satellite gear, first order satellite gear 6 and 7 engagements of first order internally toothed annulus; And be connected with second stage sun wheel 9 through first order pinion carrier 8; Second stage sun wheel 9 meshes with second stage internally toothed annulus 11 with second stage satellite gear 10 engagements, second stage satellite gear 10, and is connected with second stage pinion carrier 12; Second stage pinion carrier 12 is connected with output shaft 13, and output shaft 13 is connected with reel 3.Reel 3 is provided with caliper disk brake 14, plays quick braking action.
