Example Embodiment

[0014] Attached below figure 1 The specific embodiments of the present invention are described in detail: figure 1 In the cross-sectional view of the bearing housing for cooling fan shown, the bearing housing for cooling fan consists of hydraulic motor 1, bearing housing body 2, oil cup 3, sealing cover 4, transmission shaft 5, cooling fan mounting seat 6, rolling bearing 7, and positioning ring 8. It is composed of 9 stop washer, no welded structure, and totally dependent on structural connection.

[0015] The input end face of the bearing housing body 2 is directly fixed on the hydraulic motor 1 driving the cooling fan, and the contact surface is sealed to prevent the lubricating oil in the oil cavity from leaking.

[0016] The input end of the transmission shaft 5 is keyed to the drive shaft of the hydraulic motor 1 that drives the cooling fan, and the output end of the transmission shaft 5 is connected to the cooling fan through the cooling fan mounting seat 6. The input end ...

Abstract

The invention provides a bearing pedestal for a cooling fan. A transmission shaft (5) is inserted into a bearing pedestal body (2), and a rolling bearing (7) capable of resisting axial thrust is arranged between the transmission shaft (5) and the bearing pedestal body (2); a stop washer (9) is arranged at the input end of the transmission shaft (5); the end surface of the input end of the bearing pedestal body (2) is directly fixed on a power unit (1) by which the bearing pedestal body (2) is driven; the input end of the transmission shaft (5) is connected with the driving shaft of the power unit (1), by which the transmission shaft (5) is driven; and the output end of the transmission shaft (5) is connected with a cooling fan via a mounting seat (6) for the cooling fan. The invention has the following advantages: the cooling fan can rotate stably and smoothly, while the interaction of the axial force between the cooling fan and the power unit driving the cooling fan can be avoided in the operation, thus improving the operating reliability and service life of the cooling fan and the power unit.

Description

Technical field [0001] The invention relates to a cooling fan bearing seat for connecting a cooling fan and a driving component, in particular to a cooling fan bearing seat which can better reduce the axial force of the cooling fan. Background technique [0002] The cooling fan and the power components that drive it, such as the cooling fan and the hydraulic motor or electric motor, are usually directly connected. When this connection method is working, the axial force generated by the cooling fan itself will affect the power components that drive it, so that its working reliability and service life will be reduced; when the power components that drive the cooling fan are also working, it is generated by itself. The axial force also affects the working reliability and service life of the cooling fan. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a bearing seat for a cooling fan as a connecting device between the coolin...
