Description

Built-in forced lubrication multi-way transfer device

Technical field

The utility model relates to a multi-way transfer device, which is applied to the transmission of engineering machinery.

Background technique

The power on the transmission of construction machinery is divided into several parts, and the pressure pump supplied to the hydraulic system is used as the power source, so there is an independent transfer mechanism on the torque converter. The ordinary transfer mechanism is generally composed of transfer gears, bearings, power take-off gears, retaining rings and other components. When the torque converter rotates, the transfer gear rotates together to drive the two power take-off gears, and the splines on the power take-off gear transmit the power to the pressure pump to realize the transfer function. The disadvantage is that the lubrication of the bearing at the junction of the power take-off gear and the pressure pump is completely dependent on splash lubrication, the lubrication effect is poor, and there is a hidden danger of bearing failure.

Contents of the invention

A built-in forced lubrication multi-way transfer device, the whole device is installed in the torque converter housing, which effectively ensures the cleanliness and can solve the disadvantage of poor lubrication effect of the bearings.

The utility model is mainly composed of transfer gear 1, working pump shaft gear 2, variable speed pump shaft gear 3, steering pump shaft gear 4, steering pump connecting plate 5, bearing 6, working pump connecting plate 10, variable speed pump connecting plate 11, bearing 9 and lubrication Oil passage 11, oil passage 12 etc. are formed. The technical solution to solve the problem is: when the transfer gear 1 on the torque converter rotates with the engine, it drives the working pump shaft gear 2 installed in parallel, the variable speed pump shaft gear 3, the steering pump shaft gear 4, and the three power take-off shafts The internal splines on the gears respectively drive the pumps externally connected to the receiving plate to work. Bearings 6 and 9 are installed at the two ends of the power take-off shaft gear, and the outer rings of the bearings are respectively assembled with the working pump connecting disc 10, the variable speed pump connecting disc 11, and the steering pump connecting disc 5, and each connecting disc plays the role of fixing and supporting the pressure pump.

The casing lubricating oil passage 8 is connected with the entire transmission lubrication system, and the forced lubrication to the bearing 9 is realized through the built-in oil passage hole on the casing. In addition, the oil passage 7 communicates with the oil passages 12 on the three kinds of connecting plates to lubricate the bearing 6, ensuring that the 6 bearings at both ends are in a good lubrication state.

The utility model adopts transfer gears connected in parallel, and has the function of forced lubrication, which can automatically lubricate the bearing, can effectively improve the internal lubrication effect, has the advantage of simple assembly structure, can solve the disadvantage of poor lubrication effect of the bearing, and protect the structure.
