Problems solved by technology

However, the use of this known baffle-type hydrostatic piston engine has the disadvantage that its housing is only suitable for one corresponding rating of the specific design, so that the housing has to be produced separately for each rating of the product series

Embodiment Construction

[0027] On the front flange surface 1a of the pot case 1b, a bearing flange 1c is centrally arranged and screwed to the pot case 1b. The centering can be achieved by pins or centering flanges. The flange surface 1 a between the bearing flange 1 c and the pot-shaped housing 1 b is sealed to the outside by an O-ring 3 or a flat seal. For mounting the axial piston unit 4 , the bearing flange 1 c contains, in its front region, a fastening flange 1 d and a centering flange 2 a. In the bearing flange 1c, two bearing seats 5a are provided, each having a carrier section 5b with rolling elements held in each case. The pivot frame 5c is pivotably arranged on the rolling elements of the bearing section 5b and is held radially on the pivot frame 5c and the bearing housing 5a by a corresponding bearing flange 5d. The pivot frame 5c may also be arranged on a flat bearing seat which is pivotally arranged in the bearing flange 1c.

[0028] The bearing seat and / or the flat bearing seat 5a is...

Abstract

Disclosed is a swash plate-type hydrostatic piston engine, in which a drive unit (10) and a swash plate (17) are accommodated in a pot-shaped housing (1b). The inventive pot-shaped housing (1b) is embodied so as to be able to accommodate drive units (10a, 10b) having at least two rated quantities of a specific series of the hydrostatic piston engine.

Description

technical field [0001] According to the preamble of variant 1, the invention relates to a hydrostatic piston engine of the baffle type, provided with a pot-shaped housing which is identical for at least two ratings of the product family . According to the preamble of item 4, the invention further relates to a hydrostatic piston engine of the baffle type, the casing of which is also of pot-shaped construction and includes a cap-shaped bearing flange at its front end, the drive shaft with external drive elements can be connected to the front end. Background technique [0002] Hydrostatic piston engines of the baffle type are known in various designs, for example from DE 196 13 609 A1. However, the disadvantage of using this known baffle-type hydrostatic piston engine is that its housing is only suitable for one corresponding rating of the specific design, so that the housing has to be produced separately for each rating of the product series.
