Abstract
The utility model discloses a brake of a revolution speed reducer, which comprises a brake seat arranged around an input shaft, a bearing arranged between the input shaft and the brake seat, a fixed friction plate group connected with the brake seat, a kinetic friction plate group connected with the input shaft, a piston, a spring and a flange. The brake seat is equipped with a hydraulic oil port communicating with a piston cavity. The brake is characterized in that at least four circumferentially arranged screws of the flange are fixedly connected with the brake seat. A gap is arranged between the inner ring of the flange and the input shaft. The lubricating oil cavity of the brake communicates with the oil chamber of the speed reducer via the gap. By utilizing the brake, the disengaging of retaining rings under an impact force or other cases will be avoided. The reliability and the sealing performance of the brake are also improved.
Description
Technical field
The utility model relates to a kind of parts of wind generating unit, is specifically related to a kind of export structure that is used for the variable pitch speed reducer of wind generating unit.
Background technique
Speed reducer is a kind of power-transmitting unit, utilizes the rate conversion of gear, and the winding number of motor is decelerated to desired winding number, and obtains big torque.Speed reducer generally is used for the transmission device of low rotation speed large torque, cooperates with speed reducer, and break need be set.
The engineering rotary reducer generally adopts the third-level planetary cascaded structure at present, band Separate Brake structure, shown in accompanying drawing 1, described brake structural comprises the bearing between the Brake Block that is provided with around input shaft, input shaft and the Brake Block, movable friction plate group, piston, spring and the flange deciding the friction plate group, be connected with input shaft that is connected with Brake Block, Brake Block is provided with the hydraulic oil port that is communicated with piston cavity, described flange capping break cavity is located by back-up ring, is provided with seal ring between flange and input shaft.When hydraulic oil is injected in the hydraulic oil port pressurization, promote piston motion, disengaging friction sheet group, the speed reducer input shaft can normally turn round; When the hydraulic oil port off-load, spring promotes piston and compresses the movable friction plate group, realizes braking.Because Separate Brake structure oil filling inconvenience, and the porous plug easy to leak oil that is provided with; Back-up ring has the danger of disengaging under impact force or other situation, influenced the Security and the reliability of break.
Summary of the invention
The utility model purpose provides a kind of structural safety reliable, and oil filling is the rotary reducer break easily.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rotary reducer break, comprise the Brake Block that is provided with around input shaft, bearing between input shaft and the Brake Block, what be connected with Brake Block decides the friction plate group, the movable friction plate group that is connected with input shaft, piston, spring and flange, Brake Block is provided with the hydraulic oil port that is communicated with piston cavity, described flange is fixedlyed connected with Brake Block through 4 screws that are provided with that circumferentially distribute at least, be provided with the space between described flange inner ring and input shaft, the break lubricant reservoir is communicated with the speed reducer oil pocket through described space.
Optimized technical scheme is provided with 8 described screws, to guarantee the fixing of flange and Brake Block.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model brake spring limit structure is the screw structure by gauge hole with the back-up ring architecture advances, the danger of having avoided back-up ring to break away under impact force or other situation improves the break reliability.
2, the utility model has removed the seal ring of flange side, and break is communicated with the speed reducer oil pocket, directly partly refuels from speed reducer during oiling, and avoid break to refuel slowly to reach and refuel not exclusively, and the setting that can save porous plug, improve sealing.
Description of drawings
Fig. 1 is the structural representation of speed reducer braking device in the prior art.
Fig. 2 is the utility model embodiment one a structural representation.
Wherein: 1, input shaft; 2, Brake Block; 3, friction plate group; 4, spring; 5, piston; 6, flange; 7, screw; 8, bearing.
Embodiment
Below in conjunction with figure and embodiment the utility model is further described:
Embodiment one: shown in accompanying drawing 2, a kind of rotary reducer break, comprise the Brake Block 2 that is provided with around input shaft 1, bearing 8 between input shaft 1 and the Brake Block 2, the friction plate group of deciding that is connected with Brake Block constitutes friction plate group 3 with the movable friction plate group that is connected with input shaft, piston 5, spring 4 and flange 6, Brake Block 2 is provided with the hydraulic oil port that is communicated with piston cavity, described flange 6 is fixedlyed connected with Brake Block 2 through 8 screws 7 that are provided with that circumferentially distribute, be provided with the space between described flange inner ring and input shaft, the break lubricant reservoir is communicated with the speed reducer oil pocket through described space.
Present embodiment can be used for GS9T99 pump truck rotary reducer and carries the Separate Brake structure, and as shown in Figure 1, improving the front spring axial positioning structure is the back-up ring location, as shown in Figure 2, improves the back and locatees by screw for flange.It is reliable to improve the back structural orientation, and the danger of avoiding back-up ring to break away under impact force or other situation improves break Security, reliability.Simultaneously, remove the right-hand member seal ring, be communicated with the speed reducer oil pocket, break refuels and directly undertaken by speed reducer, has reduced the part brake refueling time, and is easy to operate.
Claims (2)
1. rotary reducer break, comprise the bearing between the Brake Block that is provided with around input shaft, input shaft and the Brake Block, movable friction plate group, piston, spring and the flange deciding the friction plate group, be connected that is connected with Brake Block with input shaft, Brake Block is provided with the hydraulic oil port that is communicated with piston cavity, it is characterized in that: described flange is fixedlyed connected with Brake Block through 4 screws that are provided with that circumferentially distribute at least, be provided with the space between described flange inner ring and input shaft, the break lubricant reservoir is communicated with the speed reducer oil pocket through described space.
