Abstract
The utility model relates to a braking mechanism of an acceleration box. A clutch seat is firmly connected with the box body, a clutch shell with a power gear is supported by two bearings and mounted on the clutch seat, inner and outer friction plate groups, a piston pressing the friction plate groups and an oil cylinder are arranged between the clutch seat and the clutch shell, which is supported by the two ball bearings, mounted on the clutch seat and axially restricted by a blocking ring, a blocking plate, a blocking ring and a spacing ring. A working oil circuit and a lubricating oil circuit which are controlled by control valves are respectively arranged on the clutch seat and communicated with the oil cylinder. The utility model can be adapted to the working conditions of high speed, high load, high-frequency clutching, etc., and is characterized by compact structure, small volume, light weight, geat capacity of power transmission, high using reliability, etc.
Description
Technical field
The utility model relates to a kind of arrestment mechanism that is exclusively used in speedup box, especially the arrestment mechanism of water pump gear speedup box.
Background technique
Because the special operation condition of water pump gear case need keep output static sometimes under the situation of main frame long-term operation, therefore,, need the band row moment of torsion of strict control gear case in order to reach this requirement, in case of necessity braking device need be set.General braking device has external manual brake dish and built-in braking device etc.Though relatively simple for structure for external braking device itself, because it need be installed on the output shaft, this will make the structure of output shaft and output flange complicated, and needs manual operation when braking, might cause the danger of misoperation.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of that hydraulic pressure multi-disc powder metallurgy friction plate is braked, as to adapt to the speedup box of high-speed, high load, high frequency time clutch operating mode arrestment mechanism that adopts is provided.
The purpose of this utility model is finished by following technical solution, it is to be fixed with clutch base on casing, have the clutch outer member that connects power gear and be installed on the clutch base by two bearings, the outside friction disc group gets final product the piston and the oil cylinder of pressing friction sheet group in being provided with between clutch base and clutch outer member.
Described clutch outer member supports by two ball bearings and is installed on the clutch base, axially respectively by back-up ring (2), and baffle plate (6), back-up ring (10) and spacer ring (9) restriction.
Clutch base described in the utility model is provided with working oil and the lubricant oil oil circuit that two-way is imported by control valve respectively, and is connected with piston and oil cylinder.
The utility model has adopted the arrestment mechanism of Wet-type multi-disc powder metallurgy friction disk clutch form, and its reliability has obtained sufficient assurance; Compared with prior art, mainly contain following several advantage: 1, brake coupling open and close with operative clutch simultaneously by hydraulic control valve control, between do not have the danger of misoperation; 2, can regulate the speed that clutch runs in by the oil-feed speed of regulating hydraulic control valve, thereby can realize regulating the braking speed of braking device, effectively slow down the impact that when braking, brings, protection axle and bearing are played a good role to output block; 3, this braking device can adapt to the situation of clockwise and anticlockwise, thereby makes the adaptability of this brake structure more extensive; Have operating modes such as to adapt to high-speed, high load, high frequency time clutch, characteristics such as compact structure, volume is little, in light weight, the transmission of power ability is big, operational safety height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: the utility model mainly is made up of five parts: clutch base 1, clutch outer member 8, oil cylinder 3, piston 4 and interior outside friction disc group 5.Whole parts link to each other with casing by six bolts on the clutch base 1, install simple and reliable; Clutch outer member 8 is installed on the clutch base 1 by the support of two ball bearings 7, axially respectively by back-up ring 2, and baffle plate 6, back-up ring 10 and spacer ring 9 restrictions.
Clutch base 1 described in the utility model is provided with working oil and the lubricant oil oil circuit that two-way is imported by control valve respectively, and is connected with piston 4 and oil cylinder 3.
During work, working oil and lubricant oil divide two-way to enter between oil cylinder 3 and the friction plate 5 through clutch base 1 respectively by the control valve input, under the pressure of working oil, make piston 4 pressing friction sheet groups 5, realize braking, simultaneously, lubricant oil cools off friction plate, has guaranteed the proper functioning of clutch.
When needs are braked, power passes to from output block on the outside friction disc of braking device by the gear on the clutch outer member, and when clutch closed row, power reached interior friction plate by outside friction disc, reach casing through clutch base again, the final purpose that realizes braking.
