Abstract
The utility model relates to a support shaft for transmission shafts of a loading machine. A bearing is fixed in a support seat with an oil cup and a temperature sensor, the support seat is connected with an end cover with an oil seal, a spline shaft fork with a sleeve penetrates through the support seat and is connected with a spline sleeve fork, a pressing plate compresses the spline sleeve fork and is fixed on the spline shaft fork, a cooling cavity with a cooling liquid inlet and a cooling liquid outlet is arranged on the support seat, the cooling liquid inlet of the cooling cavity is connected with an electromagnetic valve through a pipeline, and a one-way valve is further arranged at the bottom of the cooling cavity. The support shaft provided by the utility model has the advantages that when the front transmission shaft or the support shaft is damaged or fractured, the integral replacement is not required, and only the damaged part needs to be placed, so that the maintenance cost is low; the support strength is large, so that the support shaft can be used for a large loading machine; the support stress is uniform and the failure rate is low; the support way of the support shaft increases a pair of universal joints for connection, thus when in arrangement, the angle adjustment is convenient and the mounting is convenient; the support shaft has the cooling cavity, so that the support seat can be cooled according to temperature control when the support seat works for heating.
Description
Technical field
The utility model relates to a kind of bracing or strutting arrangement of loader transmission shaft, in particular for supporting the tween drive spindle of loader and the device of front propeller shaft.
Background technology
At present, loader mostly is articulated steering mode both at home and abroad, its front propeller shaft must support on front frame for loader, supporting way is an integrated bracing or strutting arrangement on front propeller shaft, then tween drive spindle is connected on front propeller shaft, there is following shortcoming in this structure: 1, front propeller shaft damage or need during fracture simultaneously by front propeller shaft and on bracing or strutting arrangement change simultaneously, cause maintenance cost higher; 2, integrated bracing or strutting arrangement intensity is lower, is generally applicable to underloading or middle-size and small-size loader, is used on large-duty loader undercapacity; 3, integrated bracing or strutting arrangement discontinuity when loader front driving axle input flange is eccentric, bracing or strutting arrangement easily damages or causes occurring drive shafts fracture fault; 4, loader integrated bracing or strutting arrangement when turning to needs to bear certain axial force, and the axial force that integrated bracing or strutting arrangement can bear is less, and reliability is low; 5, front propeller shaft length is longer, adjusts angle inconvenience when arranging, install inconvenient, 6, integrated bracing or strutting arrangement easily generates heat when transmission shaft High Rotation Speed, causes bearing to burn out.
Summary of the invention
The purpose of this utility model is to provide that a kind of support strength is large, stressed evenly, failure rate is low, easy for installation, maintenance cost is low and with the loader transmission shaft pivot shaft of refrigerating function.
The purpose of this utility model is achieved in that and comprises pressing plate, spline housing fork, end cap, bearing, lubricating cup, sleeve pipe, supporting seat, slip shaft yoke, temperature sensor, check valve, electromagnetic valve, cooling cavity, bearing is fixed in the supporting seat with lubricating cup and temperature sensor, the end cap of supporting seat connecting band oil sealing, slip shaft yoke with well connects spline housing fork through supporting seat, pressing plate compresses spline housing and pitches and be fixed on slip shaft yoke, cooling cavity with cooling liquid inlet and cooling liquid outlet is housed on supporting seat, the cooling liquid inlet of cooling cavity is by pipeline connected electromagnetic valve, check valve is also equipped with in the bottom of cooling cavity.
The utility model has the advantages that: when front propeller shaft or pivot shaft damage, rupture, without integral replacing, only need to change the parts that damage, maintenance cost is low; Support strength is large, can be used for large-duty loader; Support stressed evenly, failure rate is low; Can bear larger axial thrust, reliability is high; This pivot shaft supporting way has increased a pair of universal-joint and has connected, and adjusts angle convenient during layout, easy for installation; There is a cooling cavity, at work adstante febre, can control and carry out cooling to supporting seat according to temperature.
Accompanying drawing explanation
Fig. 1 is constructional drawing of the present utility model.
