Abstract
The invention discloses a multi-seal power head, and relates to the field of machinery, in particular to the technical field of manufacturing of a power head of a rotary drilling rig. The multi-seal power head comprises an input shaft, a driving gear, a rotating support, a hub, a key and an installing box body. The installing box body is arranged outside the hub in a coaxial mode. The key is fixedly connected inside the hub. The rotating support is fixedly arranged on the hub in a coaxial mode. Driven gear teeth are arranged on the rotating support. The driving gear is fixedly connected onto the input shaft. The driving gear is meshed with the driven gear teeth. The upper and lower parts of the installing box body are respectively provided with upper and lower oil seal boxes. Two framework oil seals are respectively arranged in the upper and lower oil seal boxes. By the arrangement, slurry can be better prevented from damaging the upper seal and intruding into the box body, and parts such as the input shaft, an output shaft, the gear, a bearing and the like can be prevented from being worn in an accelerated mode, so that the service life of the power head is prolonged.
Description
Technical field
The present invention relates to mechanical field, particularly the manufacturing technology field of rotary digging drill power head.
Background technology
Existing rotary drilling rig comprises power shaft, driven gear (containing revolution supports), wheel hub, key and the casing etc. of above-mentioned each part is installed; Thereby the splined shaft of power shaft through top is connected with reductor, hydraulic motor and gains impetus; Through being arranged on the driven wheel and said driven gear (containing revolution supports) engagement in the middle of the power shaft, driving the said wheel hub that is connected on the driven gear and working through the said key driving drilling rod that is installed on the wheel hub; In this simultaneously; The box house of installing parts is full of cooling, lubrication oil, and the wheel hub of casing rotation is when stretching out casing relatively, and the upper and lower of casing respectively is provided with an oil sealing box; The twice outside framework oil seal is installed in the following oil sealing box, one outside framework oil seal is installed in the last oil sealing box.The effect of this top single track sealing is bad, and when rotary drilling rig was worked, mud was prone to last sealing is damaged even get into casing, and gear, bearing are caused wearing and tearing, thereby shortened the application life of unit head.
Summary of the invention
The present invention provides a kind of many sealed motive forces head, and purpose is to overcome the unfavorable defective of an available dynamic sealing effectiveness.
The present invention includes power shaft, driven wheel, revolution support, wheel hub, key, installation casing; The coaxial outside that is arranged on said wheel hub of said installation casing; Said key is fixedly connected on the inboard of said wheel hub, and coaxial being fixed on the said wheel hub supported in said revolution, on said revolution is supported, the driven gear teeth is set; Said driven wheel is fixedly connected on the said power shaft; Said driven wheel and driven gear teeth meshing are provided with upper and lower oil sealing box respectively in the upper and lower part of said installation casing, in said upper and lower oil sealing box, the twice outside framework oil seal are set respectively.
The present invention is provided with sealing than original unit head more, and it can prevent better that mud from damage to go up invading in the casing, and can prevent component accelerated wear tests such as input, output shaft, gear, bearing, thereby prolongs unit head application life.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Among the figure, 1, power shaft, 2, the driven gear teeth, 3, wheel hub, 4, casing is installed, 5, outside framework oil seal, 6, go up the oil sealing box, 7, oil sealing box down, 9, driven wheel, 10, revolution supports, 11, key.
The specific embodiment
As shown in Figure 1, this many sealed motive forces head comprises power shaft 1, driven wheel 9, revolution support 10, wheel hub 3, key 11, casing 4 is installed; The casing 4 coaxial outsides that are arranged on wheel hub 3 are installed; Key 11 is fixedly connected on the inboard of wheel hub 3, and 10 coaxial being fixed on the wheel hub 3 are supported in revolution, supports on 10 that in revolution the driven gear teeth 2 being set; Driven wheel 9 is fixedly connected on the power shaft 1; Driven wheel 9 and the driven gear teeth 2 engagements are provided with upper and lower oil sealing box 6,7 respectively in the upper and lower part that casing 4 is installed, and in said upper and lower oil sealing box 6,7, twice outside framework oil seal 5 are set respectively.
Claims (1)
1. many sealed motive forces head; Comprise power shaft, driven wheel, revolution support, wheel hub, key, installation casing, the coaxial outside that is arranged on said wheel hub of said installation casing, said key is fixedly connected on the inboard of said wheel hub; Coaxial being fixed on the said wheel hub supported in said revolution; On said revolution is supported, the driven gear teeth are set, said driven wheel is fixedly connected on the said power shaft, said driven wheel and driven gear teeth meshing; In the upper and lower part of said installation casing upper and lower oil sealing box is set respectively, it is characterized in that in said upper and lower oil sealing box, the twice outside framework oil seal being set respectively.
